What DeepOcean does
DeepOcean is a Norway-headquartered, privately held ocean services provider founded in 1999 and owned by the European private equity firm Triton. The company delivers the full lifecycle of subsea services - survey, engineering, project management, installation, inspection/maintenance/repair (IMR), and decommissioning/recycling - for offshore oil and gas operators, offshore wind developers, and adjacent ocean industries. Headcount stands at approximately 1,800 employees across 16 countries, with regional offices in Europe, the Americas, West Africa, APAC, and the Middle East following the May 2025 acquisition of Shelf Subsea. Operationally, DeepOcean commands a fleet of 17+ vessels (owned and chartered), two onshore Remote Operating Centres in Norway, and a substantial subsea tool pool that enables execution of multiple simultaneous campaigns.
The technology stack combines conventional work-class ROVs and AUVs with proprietary assets: the Autonomous Inspection Drone (AID, awarded OTC's 2024 Spotlight on New Technology), the USV Challenger uncrewed surface vessel (delivered 2025 through a Solstad/Østensjø/DeepOcean joint venture), the UT-1 jet trencher (2,800 hp), a proprietary digital twin platform, and the patented FlowHeat subsea flowline heating system. The 'remote-first' operating model centers on onshore execution of subsea tasks: a 12-hour shore-managed subsea intervention replaces a traditional 14-day offshore trip, and the methanol-ready Rem Ocean vessel (chartered from 2027) targets 90% CO2 emission reduction.
The business model combines long-term, recurring frame agreements with major operators (e.g., 8-year Equinor 2027-2035, 5-year Vår Energi to 2030, 4-year Vattenfall European offshore wind) and project-based installation, construction, and decommissioning contracts. Recurring IMR work anchors revenue visibility while project work drives episodic scale. Strategic positioning is as a technology-led, remote-capable subsea contractor serving blue-chip energy operators across both legacy oil and gas and renewables, with growth funded by a combination of organic wins, the Shelf Subsea acquisition, and a €480 million senior secured notes issuance completed in September 2025.
