Odfjell Oceanwind

What Odfjell Oceanwind does

Odfjell Oceanwind AS is a Norwegian privately-held floating offshore wind technology specialist headquartered in Bergen, with additional offices in Stavanger, Oslo, and Aberdeen. The company designs and develops semi-submersible steel foundations (Deepsea Star™ and predecessor Deepsea Semi™) rated for 15MW+ wind turbines in harsh North Atlantic environments, alongside Mobile Offshore Wind Units (MOWUs) and the WindGrid™ hybrid power system that integrates wind generation, battery storage, and grid controls to displace gas-turbine power on offshore installations.

The company monetises through four channels: MOWU rentals to oil and gas operators for temporary or permanent electrification of offshore platforms; technology licensing of foundation designs; EPCI services for floating wind projects; and equity participation in consortium-developed wind farms (Salamander in Scotland, GoliatVIND and SCALEWIND in Norway, UtsiraVIND). Its primary customer segments are North Sea oil and gas operators facing decarbonisation pressure and floating wind farm developers requiring DNV-certified, mass-production-ready foundations.

Odfjell Oceanwind is backed by the Odfjell Group and the Odfjell family, with strategic shareholders including Mitsui O.S.K. Lines and Kansai Electric Power Company, and a 2 billion NOK Enova grant supporting GoliatVIND. The company was established through an investment in Oceanwind AS (which had 20 years of floating wind heritage), combining with Odfjell's 50+ years of maritime expertise in harsh offshore environments, and is positioning for industrial-scale floating wind through its Windsteel Technologies manufacturing JV with Prodtex.

Scale indicators7 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Ørsted: Global offshore wind leader that divested its Salamander stake to Odfjell Oceanwind in 2025; continues to evaluate floating wind in its portfolio and is both a potential licensor/customer and a competing developer of utility-scale offshore wind capacity.
• Aker Solutions: Norwegian offshore engineering, fabrication and EPCI incumbent with growing floating wind ambitions (Convergence, Hywind Tampen work). Comparable operating geography, oil & gas crossover customers, and harsh-environment execution capabilities.
• Saipem: Italian offshore EPCI major with floating wind ambitions (e.g., Neptun project), operating in similar oil & gas crossover and harsh-environment segments with comparable shipyard engineering capabilities.
• Equinor (Hywind): Operates the Hywind floating wind platform (the world's first full-scale floating wind farm) and is simultaneously an Odfjell Oceanwind partner through GoliatVIND. Equinor's captive floating wind programme competes for the same project pipeline and OEM relationships.

Regional players

• Aker BP: Norwegian oil & gas operator pursuing offshore electrification (e.g., Yggdrasil power-from-shore); a comparable oil & gas customer profile to Vår Energi and Equinor and a potential counterparty for MOWU rentals in the Norwegian Continental Shelf.

Direct peers

• SBM Offshore: Dutch offshore engineering company developing floating wind foundation concepts (e.g., Floating Power Plant / Aker SBM JVs), competing for floating wind EPCI work in Europe and the Americas using shipbuilding-derived expertise similar to Odfjell Oceanwind.
• Principle Power: Developer of the WindFloat semi-submersible floating foundation, the most-deployed floating wind technology globally and the most direct competitor to Deepsea Star/Deepsea Semi in the same product category and target customer base (European and US floating wind developers).
• BW Ideol: French floating wind foundation specialist with barge-based designs competing head-to-head against Odfjell Oceanwind's semi-submersible concepts in European tenders (e.g., ScotWind, French Mediterranean) and offering similar technology licensing and co-development models.
• Subsea7 / Seaway7: Joint venture partner with Odfjell Oceanwind on Salamander and one of the leading global EPCI contractors for both bottom-fixed and floating offshore wind; competes for installation, mooring, and cable scope on the same floating wind tenders.

Emerging players

• Flotation Energy: UK-based floating wind developer focused on the UK and Scottish seabed lease areas (Celtic Sea, Pentland), competing directly with Odfjell Oceanwind for ScotWind-adjacent projects and similar oil & gas electrification pilots.
