Who we are

Who we are

INNOSEA is an independent specialist Marine Renewable Energies (MRE) multidisciplinary engineering, strategy advisory and R&D consultancy. We support clients throughout the full development cycle of an MRE project or technology, to help unlock its commercial potential, scalability, and enhanced performance.

100% dedicated to MRE, this commitment keeps us at the cutting-edge of green technology. Our wide range of specialised services covers concept studies, basic engineering, detailed engineering, testing, and pre-certification amongst others. We conduct detailed studies to support clients in delivering technology with enhanced profitability, performance and future viability across its lifecycle. Our focus is on seven key markets in the MRE industry.

Our history

INNOSEA was created in 2012 as a spin-off company from the renowned French engineering school, Ecole Centrale de Nantes. Our mission is to deliver flexible, comprehensive and dedicated engineering services to find solutions to the biggest technical challenges facing MRE sectors. Our role is to facilitate the path for clients to bring their innovations to life, enabling transformative action in the renewable energy sector to unlock the road to net-zero.

The value we bring

It is still rare to find a ‘pure-player’ engineering consultancy in offshore renewable energy. We combine that decade-long commitment, from the early days of renewable energy, with a wide variety of engineering expertise, to apply the best practice to overcome the most challenging technical hurdles facing our industry. Our experience gives us an in-depth understanding of the specific challenges impacting marine renewable energies and their potential to accelerate the global race to net-zero.

We work closely with clients and in project consortiums, often even within client teams embedded in their offices, to find engineering solutions, which will increase the profitability of our Client’s projects while preserving the integrity of the systems through their life cycle. We understand that the commercial viability of an offshore renewable asset or farm relies on the cost-competitiveness of the asset in construction and operation.

Our services can be split into the following fields:
