Enduruns project

Enduruns project

Enduruns projet

The ENDURUNS project brings together 15 different European partners and an associated member from South Korea. The goal of this project is to develop and demonstrate a long endurance hybrid AUV (Autonomous Unmanned Vehicle) with gliding capabilities.

This hybrid AUV will be powered by hydrogen fuel cells and cooperate with an USV (Unmanned Surface Vehicle) to accomplish different missions: seabed mapping, geophysical studies, fish stock assessment, inspection of Underwater structures. The project is funded by the EU’s Horizon 2020 research and innovation program.

COMEX is developing a mechanical docking mechanism allowing the AUV to dock to an USV and a virtual based system to assist in the docking process

Our planet is covered two-third by oceans and yet only an equivalent of 15% of the oceans’ total area has been explored to some extent. This represents a vast part of unexplored and uncharted natural resources available. During the 6th June 2017 United Nations Conference, the “Seabed 2030” initiative was launched by the General Bathymetric Charts of Oceans (GEBCO) operating under the guidance of the International Hydrographic Organization (IHO) and the Intergovernmental Oceanographic Commission (ICO) of UNESCO. The goal of the “Seabed 2030” initiative is to promote international collaboration for facilitating the complete mapping of the ocean floor in 2030.

Mapping of the oceans and evaluating their resources is of great importance to global economy and societal security. It provides direct information on available quantities of resources for long-term sustainable exploitation, reliable climate change models, sustainable maritime food production chain stability, new offshore energy and mining resources, quality and status of sea habitats, potential new advanced biomedicine sources, etc.

The strong capability of identifying existing and future critical offshore infrastructure and the accurate mapping of the ocean seabed is of strategic importance to European Member States, maritime activities, policymaking, upholding the blue growth agenda and accurately assessing the state of European sets and International Waters as defined in the EC Marine Strategy Framework Directive (2008/56/EC). EMODnet is a central EU portal for the marine data and contains the existing seabed and bathymetric data acquired predominantly by carrying out bathymetry sonar measurements and multi-beam echo sounder with the help of surface vessels.

So, to achieve the objectives of the “Seabed 2030” initiative, several advancements are needed in areas like Autonomous Underwater Vehicle (AUV) design, powering, and control technology, launch and recovery methods, as well as associated communication and geotagging techniques, seabed mapping and infrastructure inspection sensing, etc.

The ENDURUNS project aims to develop a hybrid AUV glider powered by hydrogen fuel cell technology. The application of high energy density H2 as fuel in combination with the gliding capabilities of the vehicle and the support of a USV for battery recharging and data exchange will permit extended operation at sea up to several months, enabling multiple missions to be carried out even with a single launch sequence. ENDURUNS will be able to perform high-resolution seabed mapping within the 100m target specified by the “Seabed 2030” initiative as well as detailed inspection of offshore infrastructure which may require even higher levels of resolution. The sensor payload will be adaptable to the specific requirements of each mission thanks to the modularity and compatibility offered by the ENDURUNS AUV architectural design. Surveying capabilities will permit the use of the ENDURUNS system for geophysical studies, fish stock assessment, surveillance, mineral resources, offshore infrastructure structural evaluation and so on. An USV will be used in conjunction with the AUV. The USV will be capable of connecting with the AUV when required and return to port as a single unit.

The ENDURUNS consortium brings together every stakeholder associated with the relevant value chain, including specification of end-user requirements (CNR-ISMAR, COMEX, KPA), lto the implementation, testing, validation and commercialization of the AUV and USV modules (GRAALTECH, COMEX, TUCO, ALTUS, CNR-ISMAR, UOB), power train research, development and commercialization (HYSYTECH, Z-GROUP, GRAALTECH, COMEX, UOB, NCSRD, UCLM), sensing capability (ON-AIR, SWISSAPP, UOB), communication technologies (SPACEAPPS, UOB), control and navigation (GRAALTECH, COMEX, ALTUS, UOB), advanced structural fiber-reinforced composite materials technology and finite element analysis (ESI, TUCO, UOB), advanced data handling and processing (ON-AIR, ESI, UCLM, UOB),  and widespread dissemination(METIS, CNR-ISMAR, COMEX, UCLM, UOB).

The performance of the ENDURUNS system will be evaluated in an actual relevant operational scenario. Integral parts of ENDURUNS are the LCA of the developed system and its subcomponents as well as the detailed market analysis and business opportunities on which the consortium will be supported by the stakeholders participating in the Advisory Group.

COMEX SA is pleased to have won the new public contract from the French Ministry of the Armed Forces for the MCO* recompression chambers.
(* Maintenance in operational condition of the recompression chambers of the French Navy and Army).

 

COMEX SA is pleased to have won the new public contract from the French Ministry of the Armed Forces for the Maintenance in operational condition of the recompression chambers of the French Navy and Army.

Our team is in charge of maintenance for :

  • 31 hyperbaric chambers embarked on ship / container / ashore
  • 1 diving simulator chamber 500 m
  • 1 recompression chamber for the Army

For the maintenance of the French Navy’s hyperbaric chambers, the long-standing and fruitful partnership that links us began in 2009. Our team was already in charge for maintaining in operational conditions the 30 hyperbaric installations on its naval bases ashore or on board its buildings and ships.

The new contract, notified by the fleet support department, started in March 2020 and ends in March 2025. It gives COMEX the opportunity to work on all the hypobaric chambers arming the French Navy’s ships, including at the Brest, Cherbourg, Toulon, Saint Mandrier and Roscanvel naval bases, in order to carry out the regulatory inspections governed by the latest decree in force (Order of November 20, 2017).

The whole team is very pleased for this confidence renewal and for the work carried out for more than 10 years.

Our maintenance actions must guarantee the operational availability of all the hyberbaric chambers, including the maintenance of the 500-meter diving simulator in Toulon, usually called “CHM500”. Our technicians also remain mobilized to take action in case of damage so that the slightest breakdown can be repaired in less than 5 days, regardless of the location of the chamber concerned.

In addition, one of our missions will be to carry out the 10-year regulatory requalification of the 500m diving simulator; a guarantee of confidence since COMEX was already responsible for it 10 years ago.
The CHM500 center also wishes to modernize its equipment and trusts COMEX to provide innovative solutions that are adapted to their needs as well as to the particular conditions in which they operate.

A great proof of confidence for the COMEX teams specialized in hyperbaric technologies!

CX3D – On orbit 3D modeling of satellites

Figure 1 (left): Mock-up of an “uncooperating” satellite in the COMEX’ Pools. (right) Underwater acquisition of the 3D model in neutral buoyancy conditions (COMEX Pool). The 3D vision system is carried by a diver -instead of a satellite- for instance.)

Space debris are of growing concern to the global space community. One way to reduce the increase in the number of space debris added each year is by prolonging the on-orbit lifetime of the satellites either by performing on-orbit refueling or with the help of a service satellite. Most of the current solutions depend on information regarding the status of the target satellite or the debris. The target satellite could have been changed due to the effects of space weather, mechanical abrasion, malfunction and damage (especially in case of debris removal). Getting precise data on the actual state of the debris is therefore a primordial element in any mitigation strategy.
Especially in geostationary orbit, given the communication delay, a geostationary docking requires a sophisticated control system to dock with the target satellite autonomously without real-time ground assistance.

A solution for such application might come from the depths of the oceans: COMEX develops sophisticated underwater vision and photogrammetry systems that could be used in the space sector. ORUS3D by COMEX SA is the only underwater 3D photogrammetry solution certified for subsea metrology by Bureau Veritas that can create 3D models of underwater infrastructure with submillimetric resolution. The system can be used in various applications, ranging from precise cartography of archeological sites on the seabed, caves or autonomous classification of objects by underwater robots (ROV or AUV).

The system is proposed to produce high resolution and precision models of a satellite in orbit with the help of computer vision and photogrammetry . From a set of images that are seeing the same scene with various angles, CX3d will compute a model that is made of the scene interest points 3D coordinates and the position of the image.

The system has been tested for the space sector in different set-ups at the COMEX facilities in Marseille, France: COMEX performed underwater trials with a mock-up satellite to verify if neutral-buoyancy simulations of such a system could be feasible (e.g. simulating manipulations of a target satellite by a service satellite underwater in simulated weightlessness).
Also tests in dry conditions were performed with the system to verify if it could be implemented on existing space simulators.

COMEX ORUS3D photogrammetry to survey polymetallic nodules on the seabed

COMEX ORUS3D photogrammetry to survey polymetallic nodules on the seabed

COMEX ORUS3D photogrammetry to survey polymetallic nodules on the seabed

The Marseille-based company COMEX performed last week pool trials with their 3D photogrammetry system “ORUS3D” to survey and cartography polymetallic nodules in the deep sea. Such metallic concretions, mainly composed of manganese, copper, nickel and cobalt, could be harvested through subsea mining technologies as a response to metal shortages in Europe and other regions.

Novel technologies to survey the abundance of these resources are needed to quantify deposits and to chart maps of subsea habitats that need to be protected from mining activity.

COMEX ORUS3D photogrammetry system was used to create a 3D model of an area with polymetallic nodules. Such model can help in the future to predict the amount of metal that could be harvested by subsea mining systems in a specific area. Future enhancements of ORUS3D will include an automatic classification of items on the seabed that could be used to draw an inventory of resources available in a certain region, as well as zones to be avoided (e.g. due to habitats to be protected or other underwater artefacts).

ORUS3D is a contactless and non-intrusive vision system. Mounted onto any type of ROV it can operate down to 6000msw. The COMEX’ system is used for inspection and vision measurements in the offshore oil&gas sector and to reconstruct underwater sites (such as archeological artefacts).

COMEX has participated in the development of subsea mining solutions in the past, such as the “FONASURF” mineral extraction system. FONASURF was developed under the leadership of TECHNIP and was funded by the French Concours Mondial d’Innovation.

EPNER

Formerly flight test center / CEV created in 1946, now part of DGA Flight Test Dpt, EPNER trains crews involved in test flights ; theoretical courses come along practical hands-on exercises that allow in-flight tests of the aircraft characteristics, carried out under the optimum safety conditions. Trainees are : test pilots, engineers, mechanical and test engineers as well as air traffic controllers for specific test flights.

Located in Istres (60 km from Marseilles) since 1962, EPNER carries out its activities within the DGA (General Delegation for Weapons, a branch of French MOD). This gives the school a unique position between the Armed forces and the Industry on one hand, and between military and civilian testing sectors on the other hand. EPNER has been training crews in these different areas for more than 70 years.

The high quality of this training, based on teamwork between pilots, engineers and air traffic controllers, is recognized at the highest levels of the international aviation community.

 

Comex Altitude Simulator for human subject test aeronautical oxygen equipment 

 

In order to carry out hypobaric tests in the field of aeronautics and space, Comex Test Center of has been equipped since 2017 with an hypoxic chamber, also called hypobaric chamber or altitude simulator.

The possibility of reproducing in this 20m2 hypoxic room flight conditions up to 40 000 meters of altitude (131 000 feet), allows our partners, the main european and worldwide international organizations and industries in the aeronautics and aerospace sectors, to perform, with the help of our dedicated staff, tests on human behaviour, as in this case a simulation of hypoxia – and also qualification tests for equipment and materials.

Total control of extreme conditions of pressure and temperature allows our company to be involved in a very wide range of projects.

 

Hypoxia situation in COMEX altitude chamber

 

With the unit set up in the flight simulator mode, this test was designed to allow EPNER trainees to face hypoxia situations in the most realistic possible conditions.

This allowed the crew to be exposed to hypoxia in an attempt for each trainee to identify possible precursory physiological signs.

It further allowed detection of equipment failures (O2 breathing masks) or structural damage on the aircraft (due to sudden pressure loss etc.).
It also emphasized the dangers of flying at high altitude.

Under these various situations, trainees had to apply recently learned techniques to bring the crew safely back to the ground or to a possible ejection zone.

Medical supervision

Medical assistance was provided all through the test sessions by the Institute of Physiology and Medicine in the Maritime Environment and Extreme Environment “PHYMAREX” which brings together a group of doctors and nurses mainly from the Public Assistance of Marseille Hospitals (APHM) and more precisely the Hyperbaric Center of Sainte Marguerite University Hospital. Operational members are trained in hyperbaric medicine and / or emergency medicine and / or aeronautical and aerospace medicine.

Under the supervision of Dr. Mathieu COULANGE, emergency physician specializing in hyperbaric medicine, maritime medicine and aeronautical medicine. Head of the hyperbaric, underwater and maritime medicine department of Sainte Marguerite University Hospital.

ORUS 3D expands its range with the MOD300

COMEX strikes again with a miniature ORUS 3D. After the 1000, 3000 and 6000m models, here comes the MOD300 !


With the 3000m ORUS 3D subsea photogrammetry system operating around the world since 2017, COMEX managed to touch a large part of the subsea world. Involved in visual inspections, dimensional controls, metrologies and assets monitoring in the Oil & Gas industry, the 3000m ORUS 3D is also used in marine science to monitor its wildlife and flora, as well as in archaeology for reconstructing subsea wrecks. Operating the 3000m system naturally brought up constructive feedbacks from COMEX clients and partners, especially on the system size. Indeed, if mounting the 3000m system on a Work-Class ROV was always easy, its integration on a few Observation-Class ROV raised the need for a smaller version that could be deployed by lighter units (Seaeye Falcon, Super Achille 2000) or even by divers.

Following numerous and constructive discussions, at the beginning of 2019 the COMEX Innovation team took up to the challenge with a simple yet ambitious objective : design, develop and fabricate a smaller and lighter system delivering the same high quality and accuracy in 3D rendering that could be operated down to 300m by both divers and small Observation-Class ROVs. As if this was not enough, the team members wanted this 300m version of the ORUS 3D to be ready in just over six months for the OCEAN 2019 exhibition in Marseille, France.

 

We were keen to show that our team has all the knowledge, passion, creativity and reactivity to match our clients’ need in minimal time.

After six intense and fruitful months it was ready. While the 3000m system spreads its hardware between an Embedded Processing Unit (EPU) casing and a 3-casing Acquisition Unit (ACU) all made of titanium, the ORUS 3D MOD300 gathers in a compact and lighter aluminium casing (only 25kg in air and neutral in water) all the technology that allows the same sharp and accurate reconstruction of underwater subjects.

 

Keeping a high level of performance in subsea 3D reconstruction was a key factor. While we used new processors to downsize the system, we managed to keep the original optical sensors and lenses so that the same level of accuracy can be reached when surveying any subject.

Nearly a year after the idea was thrown on the table and six months from the first tests in Marseille during OCEAN 2019 onboard the COMEX MV JANUS2 through the Super Achille 2000 ROV, the ORUS 3D MOD300 has shown its exceptional versatility. When mounted on an Observation-Class ROV, inspection duration is greatly reduced by the ease of deployment, even with free-swimming spreads. And when the access is too harsh for a motorised unit, a diver can easily bring the MOD300 where no other subsea photogrammetry system went before.

Still looking too big? COMEX chose to make the third sensor removable for when size matters or a dual sensor system is simply enough. This configuration proved to be very diver friendly, especially in subsea cave surveys.

For those who wonder if such a small system can deliver good quality data, COMEX Innovation team included their improved live quality control tool. This inhouse-developed application checks all along the survey the images’ quality and all the factors that will ensure you get the properly scaled model of what you did or didn’t see due to the water turbidity. This smart feature delivers a live reconstruction of the survey as it goes so you can make sure nothing was missed and everything is recorded in the box.

With its long-range experience in subsea photogrammetry, COMEX remains a key stakeholder in subsea vision based measurement market by bringing game-changing tools to the field providing a global service 24/365, remote support and appropriate training to their clients worldwide.

Frédéric Swierczynski, diver of the extreme, came to prepare for
a high altitude dive in the lakes of the world’s highest active volcano, el Nevado Ojos del Salado in the Andes. This preparation took place in an altitude simulator, the hypobaric chamber at Comex trial and test Centre in Marseille, France.

 

Extreme altitude diving at 6,400m

 

Accompanied by Sébastien Devrient, a mountain guide and Film director, Frédéric Swierczynski prepared for this expedition to the Andes at the border between Argentina and Chile. Their final goal is to carry out a manned dive into the waters of the highest lake in the world at 6,390 m on the mountain side of the volcano Nevado Ojos del Salado.

The adventure started last year when Frédéric performed a first dive in a lake at 5,870 m on the same volcano side. However, early comers snow and ice made it impossible to carry out the dive at 6,390 m.
They return this year in order to fully achieve their goal.

These two expeditions will be the subject of a film «a drop of water on a volcano» scheduled to be released in Switzerland in 2020.

The story of this feature documentary, directed by Sébastien Devrient for Vertiges prod, will not only focus on a sporting feat but, above all, it will emphasize the human adventure. It will also propose a reflection on man’s ability to adapt to his dreams and
ambitions as well as addressing the problem of acclimatizing the human body confronted to a wild and unpredictable nature.

 

Preparation in hypoxic chamber

 

It is at Comex altitude simulator, an hypobaric chamber complex, that Frédéric Swierczynski and Sébastien Devrient came to prepare their expedition, joining equipment tests, physical training and dive procedure rehearsal. The first step was to simulate an altitude of 6,400 m and then a 20-minute immersion in chilled water at 2°C. At this altitude, one has to face the cold temperature conditions and the lack of oxygen, less than twice as rare as at sea level due to the ambient low atmospheric pressure.

They have thus been able to reproduce the different conditions they will face during this adventure, supervised by our technical teams and under the medical supervision of the PHYMAREX Institute.

 

Medical supervision

 

Throughout the experiment, a medical team from the PHYMAREX Institute, Doctor Mathieu Coulange (MD) and Doctor Jean-Charles Reynier (MD), continuously monitored Frédéric’s vital parameters – body temperature, heart rate, respiratory rate, carbon dioxyde and oxygen saturation…

Because of its immersion at an altitude of 6,400 m, this represents a huge difference in atmospheric pressure compared to a normal dive performed at sea level (1010mb compared to 440mb approx.).

 


This is a very uncommon and exceptional mission, we are taking advantage of this experience to collect as much data as possible. They will be used in publications for the scientific community,’ explains hyperbaric physician Jean-Charles Reynier

Altitude simulator

 

The ability to reproduce altitudes up to 40,000 m (131,000 feet) in this 20m² hypoxic chamber complex meets the needs of major european and global manufacturers and service companies in the aeronautics and aerospace sector, such as the validation and certification of equipment, masks, suits, helmets, communications, etc.

as well as manned tests in order to prepare and make fully aware pilots and aircrew to hypoxic risks they may have to face during an actual flight.

The close control and monitoring of extreme pressure and temperature conditions allows our company to be involved in a very wide range of projects.

PROJECT TRAILER: TANDEM OF TWO ROVERS
FOR EXTENDING LUNAR EXPLORATION

PRESS RELEASE

TRAILER system exploring lunar tubes (image: LIQUIFER)

31 October 2019 The European Space Agency (ESA) signed a contract on the development of the “TRAILER” robotic system with COMEX and its partners The German Research Center for Artificial Intelligence Robotics Innovation Center (DFKI RIC) and LIQUIFER Systems Group. TRAILER is a two-year project to test a novel architecture of robotic cooperation based on a tandem of two rovers for lunar surface exploration missions.

ESA is working with its international partners on the development of the lunar GATEWAY, the first permanent human outpost beyond Earth’s orbit. GATEWAY must be considered as a Base Camp that will serve to set-up missions on the surface of the Moon as part of the HERACLES and ARTEMIS Program. Astronauts and robots will work together to prepare the coming era of space exploration with missions to the lunar South Pole and other locations: robotic explorers will search for ISRU elements that could support a human presence on the surface. These scouts will be operated either from Earth or from GATEWAY in lunar orbit; and they will need to perform certain tasks in autonomy. The main objective of the TRAILER activity is to develop a rover system consisting of 


    • An agile and powerful rover (TRACTOR) equipped with high performance locomotion and navigation, local wireless transceiver, short-term energy storage, sample acquisition system, and
    • An active trailer (WAIN) equipped with limited locomotion and navigation, high power generation or storage and local wireless network that could assure lunar-earth communication and host a scientific laboratory for sample collection and analysis.

System components of the TRAILER project (image: COMEX)

The TRAILER activity is led by the Marseille-based company COMEX that develops the “WAIN”, a heavy lunar robotic vehicle that carries the communication, batteries and sample containers. DFKI RIC in Germany is responsible for simulations and development of the second robot, the “TRACTOR”, an agile scout robot that brings the samples back to WAIN. LIQUIFER Systems Group in Austria defines the mission scenarios of the robotic tandem and planning. The TRAILER system will be tested in test facilities at the partner organizations in France, Germany and Austria.

EUROPEAN SPACE AGENCY ASSIGNS COMEX TO SUPPORT THE UNDERWATER TRAINING OF ASTRONAUTS IN COLOGNE

EUROPEAN SPACE AGENCY ASSIGNS COMEX TO SUPPORT THE UNDERWATER TRAINING OF ASTRONAUTS IN COLOGNE

PRESS RELEASE

EUROPEAN SPACE AGENCY ASSIGNS COMEX TO SUPPORT THE UNDERWATER TRAINING OF ASTRONAUTS IN COLOGNE

COMEX and the European Space Agency (ESA) have signed a contract on astronaut underwater training at the European Astronaut Centre (EAC) in Cologne.

On May 18th, 2019, the Marseille-based enterprise COMEX (Compagnie Maritime d’Expertises) and the European Space Agency (ESA) have signed a contract on supporting the underwater training of astronauts and operations of ESA’s Neutral Buoyancy Facility (NBF) at the European Astronaut Centre in Cologne. The NBF is a unique training and testing facility housing a 10 m deep water tank, in which full scale mock-ups of International Space Station (ISS) modules are immerged. This is the only place in Europe, where astronauts receive training for Extra-Vehicular Activities (EVA) also known as spacewalks. ESA has developed and implemented in the NBF a world-wide unique EVA Prefamiliarisation Training Programme to train the European astronauts on the rules of engagement for spacewalks on the International Space Station (ISS). This programme has proven its efficiency with the multiple spacewalk assignments of ESA astronauts in the past 10 years and is also used as EVA proficiency training in Europe. “This innovative ESA training has been in place for already 15 years and is regularly enhanced through a very fruitful cooperation with NASA. Its objective is to boost ESA astronaut initial EVA capabilities in safely and efficiently performing EVA tasks, before they get exposed to the spacesuit constraints through their further EVA skill training by NASA in Houston. Having now COMEX on board is an additional and appreciated asset for the diving activities in the NBF” says Hervé Stevenin, ESA Head of the EVA training at EAC.

The NBF also offers the capability to simulate the Moon gravity through immersions in slightly negative buoyancy. ESA has already prototyped Lunar EVA equipment & tools, which have been tested in simulated lunar gravity inside the NBF tank for the preparation of the ESA upcoming contribution to the return of humans to the Moon surface.

The present contract also includes the continuation of these activities to test European lunar surface operations and hardware to prepare the return of astronauts on the Moon. “Within this contract we will provide ESA with a team of divers to support the training of astronauts underwater for missions to the International Space Station (ISS). But the project goes beyond ISS and will also serve to support ESA contribution to future human lunar exploration missions” says Peter Weiss, Head of the Space Department at COMEX. The company is working for ESA on several projects related to the future Moon exploration and is actively investigating spin-off technologies and synergies between the maritime and space sectors.

Kathrin Nowak, NBF Diver and COMEX Team Lead at the European Astronaut Centre says: “Most of the divers working for COMEX in Cologne have a long experience of supporting astronaut training and tests at the Neutral Buoyancy Facility. We are happy that we can combine the expertise of COMEX and the proficiency of the diving team to support ESA in NBF activities”.

Comex maritime expertise for neutrino research

What is a neutrino ?


Neutrinos are neutral elementary particles of virtually zero mass. They are produced during nuclear reactions generated by extremely violent cosmic cataclysms such as black holes, supernovae and the Big Bang.

Once produced, they move at a speed close to light speed. Because of their zero electric charge they move in a straight line without stopping, crossing the stars and planets as if they did not exist, all the way out to the borders of the Universe. The earth is crossed by trillions of neutrinos every nanosecond.

By their nature neutrinos are therefore extremely difficult to detect. Fortunately, on rare occasions, a high-energy neutrino collides with an atom. The collision disintegrates the atom nucleus and the neutrino transforms into another particle called muon.

The created muon continues its movement on a trajectory almost identical to that of the neutrino and can be identified thanks to the cone of blue light it generates, known as the Cerenkov radiation. In order to detect this tiny bit of light, it is necessary to use extremely sensitive detectors while operating under total darkness conditions.

Why and how to monitor neutrinos ?

 

Neutrinos contain information about the cataclysmic events that produced them. Scientists consider them as messengers.

The observation of high-energy neutrinos offers a new angle to look at the Universe.

A special kind of telescopes is used to detect and observe neutrinos. Since neutrinos almost hardly interact with matter and in order to be protected from cosmic radiation, such telescopes are usually buried underground in large liquid-filled caves.

ANTARES and KM3NeT

 

ANTARES (Astronomy with a Neutrino Telescope and Abyss Environmental Research) : At the time of its design and erection, was the largest neutrino telescope in the northern hemisphere and the first built in a marine environment. In operation since 2006, it is installed deep down 2500 msw in the Mediterranean Sea, 40 kilometers offshore Toulon (France).

The main purpose of ANTARES is the search for cosmic neutrinos generated by violent phenomena of the Universe. It consists of 900 photomultipliers spread over 12 450 meter high lines, covering a surface of 0.1 km2.

The detected neutrinos are actually the few particles that collide with the matter in the vicinity of the detector, generating a muon that is detected by Cerenkov effect (blue light radiation). Unlike

optical telescopes, ANTARES looks downwards, across the Earth. The flow of particles crosses the Earth through the southern hemisphere and rises from the ocean floor up to the surface in the northern hemisphere.

KM3NeT (cubic Kilometer Neutrino Telescope) : Designed thanks to the feedback of the ANTARES detector, this second-generation telescope is being installed in the abyss of the Mediterranean sea.

A first detector, called ARCA (Astroparticle Research with Cosmics in the Abyss), installed offshore Sicily, is dedicated to the search for high-energy neutrinos coming from cataclysms in the Universe such as supernovae or the formation and evolution of black holes. A second detector, called ORCA (Oscillation Research with Cosmics in the Abyss), is under construction offshore Toulon. It will allow a determination of the mass hierarchy of neutrinos, precisely studying the flow of atmospheric neutrinos crossing the Earth.

These underwater infrastructures are also a subsea platform for multidisciplinary experimentation, hosting numerous studies in the fields of marine, terrestrial and environmental sciences as part of the EMSO seabed observatories..

This project is financed with the assistance of the PACA Region (Contract Plan State-Region), the French State (Regional Delegation to Research and Technology) and the European Union (European Regional Development Fund).

JANUS 2 surface support

 

General presentation

JANUS 2 is a 30-meter catamaran with dynamic positioning allowing our multidisciplinary team to use a large number of oceanographic and hydrographic equipment.

Mixed campaigns may be carried out, such as : 

  • Comprehensive geophysical measurements and data gathering : Side scan Sonar, magnetometer, multibeam sonar, sediment echosounder.
  • Geotechnical measures : CPT.
  • Environmental Studies : Biology, Sediments.
  • ROV Inspections: Visual GVI/CVI, debris survey, ORUS 3D metrology, 3D submillimetre modelling.
  • Underwater work Support down to 2500 msw.
  • Shallow manned diving support vessel

The ROVs, which are constantly mobilized onboard the vessel, allow a very good combined operation of measurement tools at all times. This facilitates underwater inspection campaigns, without involving third parties and avoiding potential additional intermediate mobilizations.
JANUS 2 can operate two ROVs simultaneously, namely the 1000 msw SUPER ACHILLE ROV and the 2500 msw APACHE ROV.
Using two azimutal thrusters and two bow thrusters, JANUS 2 Dynamic Positioning system (DP) allows to carry out two different types of operations.

 MOBILE VESSEL

JANUS 2 can track one or several mobile devices equipped with transponders : Manned submarine, ROVs, AUVs etc. either in constant heading or in automatic alignment of the vessel with the target.
sur la cible.

 FIXED VESSEL

The DP system maintains the vessel in a fixed position relative to the bottom using either the DGPS system or an acoustic beacon positioned at a fixed location on the sea bottom (transponder).

APACHE ROV main features

JANUS 2 is equipped with an APACHE Subatlantic hardwired underwater observation and light work vehicle remotely operated from the surface down to 2500msw deep. The APACHE is connected to its garage called “TMS” (Tether Management System) by a 120m+ umbilical lead.

The TMS also plays the role of relay and distribution : it carries the necessary power conversion system and data multiplexing unit between the robot and the surface.The TMS is mechanically attached to a 3000m power and optical fibre cable operated by means of a dedicated drum with multicore slipring at surface level.

The APACHE/TMS pair offers a robust and safe inspection solution throughout the water column, operated either in close vicinity of complex structures as well as in continuous systematic survey inspection up to 0.8 kts navigation speed, using the DP Navigation autofollow link.

Our APACHE ROV is compact, lightweight and very agile in manoeuvring. Specific equipment and tools can be installed on request (extra electrical and hydraulic power supply available.) he APACHE can be considered as a multi-instrumented platform able to meet the specific needs of missions such as: Underwater works assistance and support, photogrammetry/submillimetre 3D metrology, debris survey, CVI/GVI, TSS, SSS/SBP etc.

At the ANTARES site

In 2012, Comex Marine Department joined the project and carried out the connection of a line of photosensitive sensors using the ROV APACHE at -2500 msw depth.

This was the first connection operation at -2500 msw carried out by means of an observation class ROV.
To meet the ANTARES work specifications, modifications had to be made to the ROV (addition of two hydraulic arms, three video channels, one optical connector cleaning system).

COMEX and the CNRS – CPPM have worked together to produce an adapted tool which was developed at the CPPM as part of the MEUST NUMerEnv KM3NeT project. 

MEUST NUMerEnv Line base Design – 2500 m

 

Following the ANTARES programme, the Centre de Physique des Particules de Marseille (CPPM, AMU-CNRS/IN2P3) launched the MEUST NUMerEnv/ KM3NeT programme.

In 2014, as part of this project, COMEX was commissioned to design the supporting platform for the photomultiplier line. This bracket was deployed at a depth of -2500 msw in order to keep the line in position, ensure its stability and allow the underwater connection through a connecting cable to the junction box.
This platform supports the “Wet matable” connection system developed at the CPPM

In collaboration with the Foselev Marine CASTOR 2 support vessel, COMEX participated in the deployment and connection of the first KM3NeT/ORCA line as well as in the implementation of an instrumented module for environmental purposes.

The conditioned line was lowered from CASTOR 2 over a 2500 msw deep seabed. Operated from JANUS 2, the COMEX APACHE ROV witnessed the positioning of the line at 25 meter distance of the Node at the depth of 2500 msw. It then unrolled the connecting cable and connected the ODI electro-optical connectors to the main onshore-connected node. The compacted line was finally released by the ROV.

System Architecture

 

The architecture of the system as designed by COMEX is the result of the feedback and know-how acquired in recent years as part of its work carried out on behalf of the CPPM (Centre de Physique des Particules de Marseille) at ANTARES and NUMerEnv/ KM3NeTt offshore installations.

The infrastructure consists of 5 “nodes” distributed around the detector. Each node has a junction box connected to 2 lines (6 groups of 4 lines). The lines are spaced 20 m apart in the dense configuration (ORCA), thus requiring high precision in laying and connection operations. Lines are interconnected and connected to the junction box via an ODI type wet matable connector.

Consequently, once the Line base is laid on the bottom, the ROV recovers the connector with the connection cable wrapped onto the structure, unfolds the cable, takes the connector to the junction box and connects it using the specific tooling developed by the CPPM.

In agreement with the CPPM, COMEX wishes to keep this architecture based on a comprehensive field feedback, in order to meet the requirements of this contract and to ensure optimal maintainability of the subsea site while limiting operational costs.

These two installations were erected at a depth of 2500 msw. After nearly 20 years of operation, ANTARES is still operational and the renewed technical choices on the NUMerEnv/ KM3NeT project have benefited from the whole of this operational feedback.

Accordingly, and referring to these multiple references and experiences, COMEX demonstrates its ability to manage maintenance projects under operational conditions for facilities such as TREMAIL(hydrophone network).

COMEX as shown a marine engineering capability for the mechanical design of structures supporting hydrophones (DGA – TMF) or lines of photosensitive sensors (MEUST NUMerEnv). Its Design Department generated the necessary tools for each operation and drafted their detailed implementation procedures.

Based on its experience and feedback gained in projects similar to the one covered by this type of operations, COMEX acquired the ability to design a system architecture that meets the needs of DGA by specifying the different sub-assemblies, managing the supply, integration, implementation of interfaces and installation at subsea site.

Through its participation in sensitive Defense activities such as the design, construction, supply and installation of a high-speed visualization system for integration on the nuclear submarines launching devices of the French Marine Nationale in 2015, COMEX has demonstrated its capacity to cope with high quality standards and to address the requirements specific to such projects.

Similarly, COMEX organization showed its ability to meet the demanding requirements of secrecy and confidentiality.

New intelligent materials for future space suits

New intelligent materials for future space suits

New intelligent materials for future space suits

All space agencies are preparing for a return of man to the moon in the relatively near future!
It is in this context that the European Space Agency (ESA) is launching the “PEXTEX” project.
The aim of the project is to identify future space combinations of new materials and intelligent textiles.
Signed on January 17, 2019, the two-year study was entrusted to the Space Department of Comex.sa, as coordinator, and to its European partners the German DITF and the Austrian OeWF.

The project aims to find, in addition to existing materials on space suits, new components to incorporate additional features. To guard against dangers, but also to analyze the environment, to monitor the health of astronauts, etc. The possibilities are numerous. For example, there are rains of micrometeorites on the lunar surface; the search for textiles capable of maintaining their structural integrity is a first-rate challenge, knowing the disastrous consequences that a combination tear could cause!
For this purpose, and in order to be better adapted to this environment, the study will allow the identification of intelligent materials such as innovative polymers such as shape-memory textiles, but also e-textiles in which electronic components would be inserted. and computer, the interest is to have materials capable of capturing, analyzing and reacting autonomously and safely.
The materials that will be identified as part of the PEXTEX project will be tested in test facilities with partner organizations in France, Germany and Austria.

Fifty years after the Apollo missions, human space exploration is at the dawn of a new era, ESA and its international partners are working to return man to the moon. Establishing a permanent presence on the lunar surface is the role of future missions. The identification and testing of such materials could be used for the development of future European space suits for extravehicular activities (EVA) on the lunar floor and these space suits should be designed to withstand longer and more frequent surface operations than during the Apollo period.

This project is part of ESA’s exploration strategy to return to the moon in the coming decades. Just like the development of GATEWAY, the future space station in lunar orbit. This station will serve as a “base camp” to perform robotic and human missions on the lunar surface. Project in which Comex.sa is also associated, in partnership with Airbus, for the development of one of the “ESPRIT” modules..

Under the direction of Dr. Peter Weiss and his close collaborators Thibaud Gobert and Makthoum Peer, the Space Department is increasingly involved in this great adventure of space conquest and especially lunar exploration, congratulations to them.

Parc National des Calanques : Monitoring of red coral populations

Monitoring of red coral (Corallium rubrum) populations in Parc National des Calanques (Marseille), five years after the initial inspection.
Observations beyond 50 m depth south of the island of Riou and in the Cassidaigne Canyon, from the ROV APACHE and the very high definition underwater photogrammetry system ORUS 3D

Within the scope of the monitoring of red coral (Corallium rubrum) populations in the Parc National des Calanques (off Marseille), the Marine and Innovation Departments of COMEX SA carried out underwater surveys beyond 50 meter depth, using an ROV (Remotely Operated Vehicle) equipped with video and still cameras together with a photogrammetric system, ORUS 3D, developed and operated by COMEX Innovation. Operations at sea were carried out on February 5 and 6, 2019 using JANUS II, COMEX catamaran DP support vessel.

The purpose of the mission was to come back five years after the initial inspection at locations where populations of red coral are growing, close to RIOU Island and in the CASSIDAIGNE submarine canyon featuring uneasy access to divers, in order to conduct quantitative and qualitative evaluations using an ROV. Operation of ORUS 3D results in millimetric accuracy measurements of coral colonies. Such datas are nearly impossible to collect using ordinary stills camera or /and laser pointers. This innovative technology provides scientists with new biometric data of deep red coral populations.

Rov Apache et sytème ORUS 3D de la Comex

ORUS 3D photogrammetry system mounted on the Comex ROV Apache

ORUS 3D is an optical system that may be interfaced with all types of submarine vehicles. Based on the photogrammetry technology, the system features three very high trifocal resolution sensors synchronized with and operated from a surface control unit located onboard the support vessel. Led lighting flashes provide an optimal lighting of the scenery. A contact free and non-intrusive measurement tool, the system provides a 3D high resolution modeling of substructures and seascapes, reaching submillimetric details and millimetric accuracy.

Selected inspection areas feature the south, south-east side of RIOU Island and the north-east and north-west heads of the CASSIDAIGNE Canyon. The southern part off RIOU Island had been surveyed back in 2013 as initial inspection site. These sites feature rock blocks positioned between 50 msw and 70 msw. CASSIDAIGNE north western head is a renown site, already surveyed by COMEX during scientific campaigns : HERMES (2009) for the german MARUM laboratory ; MEDSEACAN (2009) and “Grottes et Canyons 3D”- Underwater 3D Caves and Canyons – (2014)for the French Agence des Aires Marines Protégées (AAMP) – now Agence Française pour la Biodiversité. The inspected sites range from 200 msw down to 250 msw. Ultimately, the CASSIDAIGNE north-eastern zone was a brand new site, never explored yet. It turned out to be very rich in red coral colonies.

Using COMEX sophisticated logistics in terms of positionning, sites that had been previously inspected were easily relocated. Moreover, with the help of bathymetric datas and the use of the Apache ROV Sonar, a new red coral spot has been discovered at 240 msw in the CASSIDAIGNE north-eastern zone. Last but not least, 3D modeling datas are now being processed. They will soon prove to be a superb tool that will optimize our knowledge of the deep red coral populations.

COMEX joins AIRBUS in the development of ESPRIT the European Module of the lunar orbital space station GATEWAY

October 24th 2018, COMEX and AIRBUS signed a cooperation agreement to develop ESPRIT, one of the European modules of the GATEWAY, the future lunar space station.

The GATEWAY is the first step of human space exploration after the era of the International Space Station. It will be a basis for missions to the lunar surface by robotic vehicles and astronauts. Its assembly in lunar orbit is scheduled to start in 2023.

The GATEWAY is a planned lunar-orbit space station that will have a power and propulsion system, utilization and crew habitation modules with docking capability, scientific and extra-vehicular activity airlocks, and logistics modules. The development is led by the current International Space Station partnership: NASA, ESA, ROSCOSMOS, JAXA and CSA, for launch to the Moon in the 2020s.

AIRBUS is leading as prime one of the two parallel Phase A/B1 studies for the development of the ESPRIT module (European System Providing Refueling, Infrastructure and Telecommunications), in cooperation with COMEX S.A., Marseille and other European Partners. ESPRIT is a system, planned to be launched with the first Utilization Module (an US supplied pressurized module). It includes propellant (Xenon and Hydrazine) storage and refueling systems for the Power Propulsion Element (the first US element of the Gateway), communication systems with the Lunar base, interface points for external payloads and a scientific airlock.

COMEX joins AIRBUS in the development of this space module, by bringing in its engineering expertise and testing capabilities. The Marseille based company was a pioneer in the development of subsea systems and professional diving. Since 2012, COMEX has been actively involved in human space flight activity and stratospheric platforms.

Our hyperbaric oxygen therapy facilities are present in a large number of public and private medical units around the world.

Hyperbaric medicine today

 

Hyperbaric medicine, also known as hyperbaric oxygen therapy (HBOT), involves administering oxygen to a patient at a pressure above atmospheric pressure.

 

Treatments of different pathologies

 

This medicine allows the treatment of many urgent or chronic pathologies.
The treated patients are installed in a hyperbaric oxygen therapy chamber and are brought to an air pressure equivalent to 1.5 bar (2.5 ATA).
Each patient will be administered pure oxygen following a protocol predefined by the Hyperbaric doctor.
All the following pathologies can be treated: (Non-exhaustive list)

. Decompression sickness (diving accident)
. Carbon monoxide poisoning
. Sudden deafness
. Gas embolism
. Necrotizing soft tissue infection
. Chronic refractory osteomyelitis
. Extended burns
. Radiation-induced lesions
. Ulcers or ischemic gangrenes
. Etc…

 

Therapeutic effects of hyperbaric medicine

HBO restores sufficient oxygen pressures in ischemic tissue, limits edema, protects against reperfusion aggression and facilitates healing
It increases the bactericidal power of polynuclear, potentiates certain antibiotics and acts directly on bacteria. The increase in pressure also makes it possible to fragment the intravascular gas sleeves in case of arterial gas embolism. This therapy increases the oxygen supply to damaged tissue and speeds up the healing process.

 

New leads for hyperbaric medicine

L’hyperbaric oxygen therapy promises, through scientific studies, a great potential to improve the condition of people suffering from stroke (Cerebral vascular accident) by waking up the brain with oxygen. It is also studied for Alzheimer’s disease and in the test phase in fibromyalgia.

The Hyperbaric Center at Sainte Marguerite Hospital in Marseille

Privileged partner for many years the hyperbaric medicine service of AP-HM and Comex have long been used to working together. This collaboration, reinforced by geographical proximity, makes it possible to form a high-quality medical-technical platform for biomedical research and development in the field of extreme environments.

In 2004, the AP-HM set up a hyperbaric center at the Sainte Marguerite de Marseille hospital. Designed and installed by our company, we also provide maintenance.

The hyperbaric center is currently headed by Dr. Mathieu COULANGE, Head of the Department of Hyperbaric, Underwater and Marine Medicine.

 

The Hyperbaric Center has three rooms multiplaces :

1) A “Chronic” room for chronic outpatient treatment. (8 seats).

2) A room “REA” which is an emergency room of resuscitation (2 elongated places). It also makes it possible to carry out, among other things, vascular explorations in pressure such as transcutaneous pressure and Doppler laser flow..

3) A “HYPO / HYPER” chamber that allows hyperbaric and hypobaric functioning.

– Chronic hyperbaric treatments (2 elongated places or 3 seated places).

– Pathophysiological studies in hypobaria.

The structure also includes consultation rooms that allow medical visits of no contraindication to recreational diving and medical aptitude for interventions in hyperbaric environments for professionals.

To know: The center of hyperbaric medicine of the APHM is currently the only one in France to have a hypobaric chamber which allows, among other things, to carry out studies at flight crews of aeronautics.

More generally, the APHM wants to be a center of excellence in research and teaching in the field of medicine applied to extreme environments. This is true for the maritime domain but also for the aeronautical field.

A constant modernization of the hyperbaric center

 

After the replacement of the computer system by the last generation, the COMEX teams have again intervened to modernize the hyperbaric center in 2017.

Indeed, the teams of our Services Department have installed on the 3 chambers of hyperbaric oxygen therapy, a new adapted lighting system much more efficient and economical (LED technology) which has significantly improved the comfort of patients and staff caregiver.

« Since our partnership with Comex, we have taken the option of modernizing our Hyperbaric and Hypobaric chamber. In 2017 we replaced our less efficient halogen lighting with LEDs, which is much more pleasant with the possibility to switch from a white light to a blue light that has the property to soothe patients and allow them to rest which is very pleasant for them during daily oxygen therapy sessions. It is also a comfort for the nursing staff during the care »

Comex becomes a biomedical research center

Comex becomes a biomedical research center

Our company specializing in hyperbaric and hypobaric engineering has just been awarded by the Regional Health Agency, accreditation authorizing it to practice clinical research involving the human person within our premises.

 

What is biomedical research?

 

 

Field of study that aims to improve knowledge about health. To do this, it is based in particular on the collection, with volunteer subjects, of biological and / or medical information.

Biomedical research relies on a step-by-step process, from conception to analysis of results. In order to ensure maximum security for subjects, researches are strictly regulated by law in France:

  • They are studied and conducted by multidisciplinary teams of qualified people (doctors, technicians, statisticians, nurses …).
  • These teams work according to an established protocol.
  • Authorities control researches (National Agency for the Safety of Medicines and Health Products or ANSM, Committee for the Protection of Persons or CPP).
  • Throughout a research, committees generally monitor its progress.

 

This biomedical research accreditation concerns two locations at Comex premices.

 

1)  Hyperbaric and Hypobaric Test Center

• Dedicated test facilities (altitude simulator and dive simulator)
• A medical consultation room
• Real-time video and audio monitoring system: to ensure the inside and outside interface of the hypobaric chamber
• A medical oxygenation device available without delay inside / outside the chamber
• A DAD defibrillator + emergency cart
• Resuscitation equipment within the immediate vicinity of the chamber
• Medical monitoring and control devices of the subjects

2) The test pools

The studies will apply to healthy subjects aged 18 to 65 and will focus on physiological topics only.
The medical assistance will be provided by the Institute of Physiology and Medicine in the Maritime Environment and Extreme Environments “PHYMAREX” which brings together a team of doctors and nurses coming mainly from the Public Assistance of Marseille Hospitals (APHM) and more precisely from the Hyperbaric Center of Sainte Marguerite University Hospital. They are trained in hyperbaric medicine and / or emergency medicine and / or aeronautical and aerospace medicine.

They will work under the supervision of Dr. Mathieu COULANGE, Md an emergency doctor specialized in hyperbaric medicine, maritime medicine and aeronautical medicine. Dr COULANGE is Head of Sainte Marguerite University Hospital department for hyperbaric, underwater and maritime medicine. 

“We are pleased with this approval because it mainly concerns hospitals. It is seldom attributed to private companies. However, this approval is not new to COMEX who worked with it for the development of manned deep dives under hydrogen and helium mixes during the 80’s and 90’s.

Design a lunar base using 3D printing technologies

Waste is a resource! even on the moon

January 8, 2018. The European Space Agency (ESA) entrusted the URBAN Consortium, which includes COMEX in Marseille, LIQUIFER Systems Group and SONACA Space GmbH, under the direction of OHB System AG, the study “Designing a lunar base using 3D printing technologies”. The team will evaluate the feasibility and implementation of additive layer manufacturing in the construction, operation and maintenance of a lunar base.

Logistics and bringing needed items into space or onto a planetary surface remains as one of the major constraints in long-term human space missions. Experts across the space sector have shown great interest in the utilization of lunar resources as the next logical step in implementing a global strategy for human exploration of the solar system.

Therefore, the key to any sustainable presence in space is the ability to manufacture the necessary structures, items and spare parts, on-site and on-demand. This can reduce the cost and volume of cargo missions launched from Earth, if a substantial portion of the elements needed for long-duration missions can be produced locally. Additive manufacturing technologies represent a potential solution to this goal, as they can reduce lead times from design to implementation and reduce manufacturing waste, while increasing recyclability and the ability to produce optimized parts. on demand.

The URBAN study will examine the capacity of these additive manufacturing techniques by carrying out two parallel surveys. The first concerns the mapping of the material required for a permanent human lunar base. The other survey is an analysis of available additive layer manufacturing technologies and their potential capabilities in a lunar environment. The assessment includes the state of the art 3D printing related to many materials such as metals, polymers, ceramics, concrete, food ingredients, living tissue and even … waste.

Design of a special hyperbaric machine for the SuperGrid Institute

Design of a special hyperbaric machine for the SuperGrid Institute

Design of a special hyperbaric machine for the SuperGrid Institute

Special machine for hyperbaric tests up to 40 bar internal pressure to validate the submarine connection concepts for offshore high voltage electrical cable networks. In addition to its imposing size, this hyperbaric chamber has the distinctive ability to perform combined tests on submarine systems of high-voltage cables, including water pressure, dielectric stresses, and temperature cycles. The hyperbaric chamber will allow the integration of one or two input cables and one output cable to allow the creation of an electrical circuit.

In 2017 the SuperGrid Institute entrusted COMEX with the design, realization, and integration of this hyperbaric enclosure.

 

A few technical features of this special tool :

 

  •  Combined tests of cables and connectors up to 40 bar pressure and 60°C temperature
  •  Stainless-steel hyperbaric chamber equipped with a porthole and two lights
  •  Self contained handling system necessary to operate this 5 meter long / 10 tons equipment
  •  Innovative 50 bar pressure and watertight feedthroughs for large dimension cables
  •  Provision for various configurations of input and output cables, different in numbers and diameters

 

International standards such as IEC61886 are considered as the basis on which these tests will be carried out. However, many of the tests to be carried out by the SuperGrid Institute relate to new technologies. Therefore they will not correspond to any existing test standard. This innovative test chamber ensures that the electrical performance and the mechanical integrity of the design conform to the specifications of the product. Any water leak, any dielectric or mechanical degradation would lead to a non-compliant result.
In December 2017, the innovative concept of the cable-gland was successfully validated in the CE 1000 test chamber, one of COMEX Hyperbaric Test Center tools.

The SuperGrid Institute for Energy Transition (ITE) is a platform for collaborative research in the field of low-carbon energy, bringing together the skills of industry and public research in a public-private co-investment logic and close collaboration between all the players in the sector.

The objective of the Institute is to develop technologies for SuperGrid, namely the future networks transporting electrical energy, using direct and alternating current at high voltages (in the order of a million volts). These networks are designed for the large-scale routing of energy produced from renewable sources remote from the centers of consumption, including a significant part located in the ocean (offshore), and which will allow, together with the means of flexible storage, to manage the intermittent nature of renewable energies and to ensure the stability and security of the network.

ESA astronauts tested replicas of the NASA Apollo mission tools, which were manufactured by COMEX, during a training session held at the Lanzarote Geopark on the ESA (European Space Agency) Spaceflight Analog grounds.

The PANGAEA-X training which took place on two geological sites is intended for astronauts’ drills.

PANGAEA-X is designed to carry out technological, operational, and scientific experiments, intended to improve the operational readiness and realism of future PANGAEA training and to assist the ESA in preparing future human and robotic missions.

Hervé Stevenin, the ESA instructor, explains: “It is essential to optimize the tools and equipment for the exploration. Safety and efficiency will be the keys to the success of the upcoming trips on the Moon.”

La Comex installe un simulateur de vols dans son caisson hypobare

In its continued desire to strengthen its partnership with the aeronautics and space industrial sector, COMEX has equipped its Hypobaric Test Center with a flight simulator capable of reproducing aeronautic and spatial flights.

In the altitude simulator, a habitable hypobaric chamber of 20M2 it is possible to reproduce any altitude down to a complete vacuum. This simulator will permit tests on humans at different altitudes, such as, for example, the awareness of hypoxic risks for pilots and students while flying, but also for tests on equipment, mask, combinations, helmet, etc.…

The close collaboration between the services will allow the Space Department to test a simulation of controlling a lunar or Martian rover soon.

• Modernised by the collaboration of the teams of the Engineering Department and the Services Department of the COMEX, the hyperbaric chamber of the University Hospital of Saint-Pierre, on Reunion Island, received this year a new lighting system, in as part of an operation to replace the vision Windows, which have reached the limit of validity. Developed for our new range of hyperbaric oxygen therapy facilities Cx2, this system has the advantage of significantly reducing the electrical consumption associated with the Chamber lighting and the enclosure’s Airlock, significantly reducing the costs of maintenance of the installation by making the 10-year replacement of the lighting Windows useless and greatly improving the luminous comfort inside the box.

The Sud reunion hospital group is equipped with a hyperbaric chamber since 1982. But it was in 1997, that a real hyperbaric care unit comprising dedicated premises, a hyperbar Chamber and staff was created within the Hospital of Saint Peter. This hyperbaric oxygen therapy unit is integrated into the emergency/SMUR/UHCD service. Initially under the responsibility of Dr Jan Dick HARMS, she is now led by Dr Cyril D’Andrea. The activity is supported with approximately 2600 sessions equivalent to one-seater/year. The service deals with various pathologies such as delayed healing, sudden overhearing and diving accidents… An important nursing activity (dressings) has been developed with more than 700 dressings made per year. The service has also developed a counselling activity on wounds and scarring, treatment of wounds by negative pressure and measurements of trans-cutaneous oxygen pressures. The recruitment of this unit is regional, a 24-hour permanence is ensured for emergencies.
