Doris Group opens a new branch in Nantes dedicated to Marine Renewable Energy
With over 1,000 employees worldwide, Doris Group is a leading player in engineering, project development, and energy-related services. Originally focused on conventional energy, the company—founded in 1965—has built significant expertise in renewable energy, particularly offshore wind power.
“We supported the development of fixed-bottom offshore wind in the UK, a pioneering country in this field, and contributed to many floating wind projects in various countries,” says Olivier Langeard, head of the new Nantes branch.
Innovative solutions in emerging energies
Doris Group operates across the entire project lifecycle—from design to operations—offering engineering, project management, technical support, and more. The company works on innovative concepts in renewable and emerging energies, such as:
- Deep-sea water-based air conditioning for Kingston Airport in Jamaica,
- An offshore hydrogen production unit at the base of a wind turbine in the UK,
- And the Nerehyd floating platform, developed in partnership with Lhyfe to produce green hydrogen offshore near Saint-Nazaire.
“We combined our expertise in hydrogen production with our offshore development experience,” explains Olivier Langeard.
Nantes, a strategic hub for Marine Renewable Energy
Former R&D Manager at Doris France in Paris, Olivier Langeard moved to Nantes a few months ago as part of the Lhyfe partnership.
“The idea of setting up a team here focused on marine renewable energy became obvious due to the region’s strong potential. In the short term, we aim to build a team of four to five people, depending on market opportunities, to work on marine operations, naval architecture, mooring systems, seabed studies… and perhaps even wind propulsion.”
Olivier Langeard praises the key role played by Nantes Saint-Nazaire Développement in “opening doors and helping us integrate into the local ecosystem.”
From Nantes, Doris Group is already working on several major programs such as:
- HOPE, a prototype for offshore hydrogen production with Lhyfe,
- And the future FloWatt tidal farm in Normandy.
