(Compagnie Maritime d’Expertises)


COMEX was born from a passion: the sea and its riches, and an ambitious project: pushing the boundaries of underwater work to extreme depths under perfect safety conditions, while empowering humans to ensure the perfection of their work.

Today, and after over 60 years of existence, it is still the same passion that drives everyone in this remarkable industrial and technological story. COMEX remains more than ever focused on the design, development, and operation of innovative and high-performance systems, whether they are intended for use on land, at sea, or in space. Since the company’s inception, the same values have always inspired the COMEX teams and formed the corporate culture. These values guide us in our missions:

PASSION that unites us and makes the complex possible,
EXCELLENCE that commits us to completing our missions,
INNOVATION which is our DNA, driving development,
INTEGRITY as our compass and foundation of our relationships,
SOCIAL RESPONSIBILITY that guides our involvement in the community and places humans at the center of our interactions and projects,
AGILITY for constant adaptation to the expectations of stakeholders.
