Sustainable development of marine and coastal environment

Marine Environment, Coastal Development and Oceanography. CREOCEAN provides multidisciplinary expertise, in France and worldwide, to enable a better understanding of coastal and offshore marine environments. As a former operating subsidiary of IFREMER (French Research Institute for Exploitation of the Sea), CREOCEAN is closely connected with the world of science through links with the French National Centre for Scientific Research (CNRS), universities and engineering schools, and is constantly involved in research and technological innovation.

For each of our projects, we provide environmental expertise focusing on:
  • the protection of natural legacies such as rare species, biodiversity and ecosystems, coastal and underwater ecosystems
  • sustainable coastal and maritime development through the efficient management of coastal and marine resources and by resolving problems of conflicts between different activities
CREOCEAN is part of Keran, an independent group (550 staff, € 54 million turnover).

A proximity to our clients

CREOCEAN has a network of agencies along the French coasts and in the overseas territories. Our head office is located in La Rochelle and we have local agencies in Bayonne, Montpellier, La Seyne-sur-Mer, Nantes and Caen. The overseas agencies are in Martinique, Guadeloupe, Reunion Island, Tahiti, and New Caledonia.

For international markets, CREOCEAN has established a number of international subsidiaries and representation offices. It also benefits from the presence of Keran’s international entities.

Our local presence has enabled us to develop close working relationships with our clients. This allows us to be attentive to their needs and offer the most effective solutions while providing them with the experience and expertise of all our staff and experts.



Coastal areas are subject to increasing development all over the world. It is nowadays acknowledged that urban, industrial, agricultural and even tourism development close to the coast or at sea must be carried out in conjunction with environmental protection.

CREOCEAN’s extensive experience throughout the world and multidisciplinary scientific approach has given the company a hands-on understanding of sustainable coastal development.

Our commitment is to provide assistance and tools to ensure that the development of coastal areas for economic purposes respects inhabitants and the natural environment.

Our solutions always result from the combination of two concerns:
  • The protection of human and natural legacies: Rare species, biodiversity and ecosystems, coastal and underwater landscapes must be managed rationally to achieve sustainability.
  • Balanced and sustainable development of coastal activities: Any urban, industrial, harbour- or tourism-related development can have implications for activities nearby. Our goal is to avoid harmful effects and conflicting uses by fostering a rational use of coastal and marine resources.

Quality and Safety

CREOCEAN employs a Performance Management System which allows us, on the one hand, to identify hazards linked to our operations and reduce health and safety risks at work, and on the other, to take measures to reduce our environmental impact.

The quality of our expertise and client satisfaction are also measured under our Performance Management System.

Thanks to its commitment to occupational health and safety, in 2018 and for 3 years, CREOCEAN'S head office was certified OHSAS 18001 by Bureau Veritas.

In 2021, CREOCEAN adapted and migrated to the new ISO 45001 standard with agility and success!
