French marine renewable energy specialist Innosea is to rebrand as OWC.
The name change, which is due to take place in July, finalises Innosea’s integration into sister company OWC.
Innosea’s co-founder and OWC’s regional director for Europe Hakim Mouslim (pictured) said: “Since 2012 we have built a reputation in the French market as a go-to and dedicated technical consultancy in marine renewable energy technologies.
“In time and since joining ABL Group, we have successfully expanded our work to Asia, Africa, and the Americas.
“This is the natural next step in our journey. By joining forces under the OWC brand, we’re unlocking greater synergies, expanding our reach, and offering even more comprehensive solutions to our clients worldwide.”
Innosea’s expertise in research and development, climate change risk assessment, technical advisory, owner’s engineering, WTG loads and floating solar PV, will be consolidated within OWC.
Owner ABL Group said the move strengthens the group’s offering to support renewable energy and environmental technologies from concept to operations, while further bolstering OWC’s overall capabilities.
The rebranding will also expand OWC’s geographical reach to France, enabling it to support the country’s offshore wind development and wider energy transition.
OWC chief executive Will Cleverly said: “Innosea has already been working closely with OWC, as our French branch since 2021 – we share the same culture and values and combine an extensive track record across offshore wind and energy transition technologies, both in France and abroad.
“Officially as one company, we can pool more resources, a wider breadth of engineering disciplines and experience, and leverage our global footprint to bring the cutting-edge services that we provide, to benefit more markets, both onshore and offshore.”
Meanwhile Innosea’s structural, hydrodynamics, and foundations engineering teams have moved to the group’s design house, Longitude. This transition consolidates the group’s capability in offshore wind design, forming a team that can deliver from concept to detailed design and installation engineering. It also gives Longitude an established platform to support the French market.
“Longitude has long served French renewable energy development, predominantly in marine operations engineering,” said Jan-Erik Berg, global director of Longitude’s offshore wind design. “It is exciting to have a formal base to provide more localised support to the French offshore and other renewable markets.”
