What Deep Ocean Group does
DeepOcean is a privately held (Triton-owned), Jersey-incorporated subsea services provider founded in 1999, with operational headquarters in Oslo and a global workforce of approximately 1,800 employees across 16 countries. The company delivers full-lifecycle offshore services — survey, engineering and project management, inspection/maintenance/repair (IMR), subsea installation and cable laying, trenching, decommissioning, and recycling — to major international oil & gas operators (Equinor, Vår Energi, Aker BP, bp, TotalEnergies, Woodside, Diavaz) and offshore wind developers (RWE, Vattenfall, Equinor-Polenergia). Revenue is generated primarily through multi-year frame agreements (e.g., the 8-year 2027–2035 Equinor IMR contract, 5-year Vår Energi IMR, 4-year Vattenfall cable O&M) and project-based fixed-price or unit-rate installation/decommissioning scopes, delivered via a chartered fleet of approximately 20 vessels, 40 ROVs, and 16 trenching assets with onshore Remote Operating Centres at Haugesund's Killingøy and Aberdeen.
The business model is relationship-driven enterprise field sales, organised by regional Managing Directors across Europe, UK, Americas, and Offshore Renewables, with no channel intermediaries. DeepOcean's competitive positioning rests on proprietary technology — the award-winning Autonomous Inspection Drone (AID), the jointly developed USV Challenger uncrewed surface vessel with 30-day endurance, the UT-1 jet trencher, and a digital twin platform — combined with deep operational integration into clients' subsea infrastructure. Recent strategic moves (2024–2026) include taking 100% ownership of the Equinor PRSI pool contract from the TechnipFMC JV, the May 2025 acquisition of Shelf Subsea extending the group into APAC and MENA, the launch of USV Challenger, the chartering of new high-spec vessels (Orient Adventurer, Rem Ocean newbuild for 2027), a €480 million senior secured notes issuance in September 2025, and market entries in Poland and Saudi Arabia.

Revenue model
- Subsea Services (Inspection, Maintenance, Repair - IMR): DeepOcean generates the majority of its revenue from subsea IMR services delivered through long-term frame agreements with major energy operators (Equinor, Vår Energi, Aker BP). These multi-year contracts provide a recurring revenue base with call-off work orders. Services are delivered using chartered vessels and the company's extensive subsea tool pool, with engineering and project management provided from onshore offices.
- Subsea Installation & Construction Services: Revenue from installation and construction projects including cable laying (offshore wind inter-array cables), SIMOPRO (simultaneous marine operations), subsea tie-back installations, and riser replacement. Projects are typically awarded as fixed-price or unit-rate contracts for specific scopes of work. The Nordseecluster A project demonstrates this stream, involving 48 inter-array cables across a 660 MW wind farm.
- Offshore Decommissioning & Recycling: DeepOcean generates revenue from subsea decommissioning projects including FPSO disconnection, riser/umbilical recovery, subsea infrastructure removal, and recycling. Projects like Foinaven (bp), Gryphon Alpha (TotalEnergies), and FPSO recycling demonstrate this stream. Uses innovative sale-and-purchase commercial models that recover value for clients.
- Offshore Wind Survey & Trenching Services: Revenue from subsea survey campaigns and cable trenching for offshore wind developers. DeepOcean deploys survey ROVs (Superior SROV), the UT-1 jet trencher, and survey vessels (Edda Flora) for pre-installation surveys, UXO mapping, cable burial, and post-installation monitoring. Contracts with RWE, Vattenfall, and Equinor/Polenergia illustrate this stream.
