What Doris does

DORIS Group is a privately held French energy engineering, advisory, and project management firm founded in 1965 and headquartered in Paris, with share capital of €3,559,424. The company serves international and national oil companies, renewable energy developers, governments, and new-energy operators across more than 17 countries, delivering integrated engineering from concept and feasibility studies through FEED, EPCm, and asset management. Its core service lines are engineering, consulting, project management, technical assistance (under the STAT brand with 160+ consultants), asset management (via 100%-owned ODE Asset Management focused on the UK Continental Shelf), and digital solutions, supplemented by a portfolio of proprietary products: the NereWind™ semi-submersible floating wind platform, the AWC articulated wind column for 70-250m water depths, NereHyd™ (offshore green hydrogen via partnership with Lhyfe), the GHG MasTER SaaS platform for greenhouse gas emissions monitoring, and BlueBase™ for digital asset management. DORIS also expanded its technical depth through the 2024 acquisition of WINDGLAZ for offshore wind load and aerodynamic modelling.

The firm's go-to-market is enterprise, project-based, and won primarily through competitive tendering, direct business development, and multi-year framework agreements with major operators — notably a 5-year global framework with bp covering offshore wind concept through detailed design. DORIS augments its service revenue with productized IP (floating wind and hydrogen platforms, digital SaaS) and earns the bulk of its income as professional services fees, with a smaller recurring component from digital subscriptions. Strategically, DORIS is repositioning from a conventional oil & gas EPCm base toward energy transition verticals, evidenced by the CCS Hub Alliance (Axens, AWT, SeaQuester, Surbana Jurong), the Pipeline Transition Alliance with ROSEN and SPIECAPAG for hydrogen pipeline repurposing, an Assystem collaboration on hydrogen and offshore grids, the DORIS MMC joint venture in Malaysia, and a multi-gigawatt offshore wind portfolio spanning the UK, Ireland, and South Korea.
