DeepOcean
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.

DeepOcean Finalizes Subsea Construction for Teal West Development Project
DeepOcean has successfully completed the subsea construction and tie-in work for the Teal West development, located on the UK Continental Shelf, for Anasuria Operating Company. This project involved the installation of a flexible production riser, flowline, and umbilical to connect the Teal West subsea Christmas tree to the Anasuria FPSO. The completion of the Teal West project is significant as it showcases the collaboration between operators, contractors, and service companies in the UK North Sea, particularly during uncertain times for the industry. Richard Beattie, CEO of Anasuria, emphasized the importance of such projects in maximizing the value of existing infrastructure and supporting domestic energy production. Looking ahead, the Teal West development includes two production wells and a water injection well, with the first production well connected to the Anasuria FPSO via approximately three kilometers of subsea flowlines. No further timeline was disclosed at the time of publication.
DeepOcean Completes Subsea Infrastructure Removals for Spirit Energy in North Sea
DeepOcean has successfully completed the recovery of the subsea wellhead protection structure at Spirit Energy's Seven Seas field and disconnected subsea infrastructure at the Grove West field in the North Sea. This operation utilized proprietary tooling developed in-house for decommissioning and was executed using the high-specification construction vessel Edda Freya. The project is part of Spirit Energy's broader decommissioning program for the Seven Seas and Grove West fields, aiming to maximize material recovery and minimize waste. DeepOcean's operations, managed from Aberdeen, UK, have ensured that all recovered materials are either reused, recycled, or disposed of responsibly, contributing to environmental sustainability. Looking ahead, DeepOcean's successful execution of these subsea removals positions them well for future projects with Spirit Energy. The company has demonstrated its capability in subsea decommissioning, with a focus on efficiency and environmental responsibility, as highlighted by the recycling of over 95% of materials from decommissioned assets.
