Oslo-based subsea specialist, majority-owned by Triton since 2016, runs ROV, IMR and decommissioning operations for offshore energy clients.
DeepOcean is a Norwegian ocean-services company headquartered at Ruseløkkveien 26 in Oslo, with additional operational hubs in the United Kingdom, United States and Mexico. Its operating entity, DeepOcean AS, was established in 1999; DeepOcean Group Holding AS was formed in May 2011, and in 2012 the group took its current shape through the merger of DeepOcean AS, Trico Offshore Ltd and CTC Marine Projects Ltd. In late 2016, Nordic private-equity firm Triton became the company's largest shareholder. DeepOcean describes itself as a technology-driven, independent provider of subsea services, delivering full-lifecycle work that spans survey, project management, engineering, installation, inspection-maintenance-and-repair (IMR), seabed trenching, inter-array cable installation, subsea removals and decommissioning, and recycling. It serves clients across offshore renewables, oil and gas, and ocean minerals, operating remotely operated vehicles (ROVs), subsea construction vessels and tooling, and running a remote first model built around onshore Remote Operating Centres that allow project teams to control offshore operations with reduced personnel and emissions. In July 2026, DeepOcean completed subsea infrastructure decommissioning removal work for Spirit Energy in the North Sea, part of its ongoing decommissioning and IMR business for North Sea oil and gas operators; the company has also carried out contract work for operators including Equinor. DeepOcean has expanded through a series of acquisitions: Searov in 2017, Delta Subsea in 2018, a majority stake in seabed-minerals company Adepth Minerals in 2021, Norwegian engineering firm Installit AS in April 2022, and Shelf Subsea in May 2025, the last of which extended DeepOcean's operations into the Asia-Pacific and Middle East regions. According to Wikipedia, the company employs approximately 1,537 people. DeepOcean positions itself around sustainability and the energy transition, citing its integrated health-safety-environment-quality (HSEQ) approach, proven subsea track record, and technology-driven remote operations as differentiators versus traditional ship-and-crew-heavy subsea contractors. Its service lines directly support both legacy oil-and-gas infrastructure maintenance and decommissioning and the buildout of offshore wind and other renewable energy infrastructure, making it one of the larger independent subsea-robotics and marine-construction service providers operating in Northern European and increasingly global offshore markets.
