Global ocean services provider DeepOcean has been engaged to support the subsea decommissioning and disconnection of a FPSO currently located in the UK sector of the North Sea.
DeepOcean’s scope of work includes hydrocarbon and chemical injection flushing, isolation and disconnection of subsea trees, manifolds and pipeline infrastructure, disconnection of risers and dynamic umbilical, riser and mooring chain severance and recovery, and FPSO sail away and tow to shore.
“This is a significant project encompassing both subsea and topside scopes that strongly aligns with our extensive experience. Our innovative approach has been successfully demonstrated across many complex projects and it’s our teamwork and proven capability that will drive a safe, efficient removal of subsea infrastructure, along with the safe towage of the FPSO,” says Robin Mawhinney, Executive Vice President for DeepOcean’s EMEA region.
The project will be managed and executed by DeepOcean’s operations in Aberdeen, UK. The company’s UK team brings significant decommissioning experience, including work on similar subsea infrastructure and FPSO removal projects on the UK continental shelf.
“Execution will build on the methodologies and proprietary tooling that was pioneered at the disconnection of the Gryphon Alpha FPSO last year, enabling the full scope to be delivered entirely without the use of divers. This a testimony to the team’s successful delivery of decommissioning scopes in the region,” says Gary Scott, Commercial Director for DeepOcean’s EMEA region.
For the Gryphon recycling project, DeepOcean was recently recognized with the ‘Best Safety Improvement Award’, together with TotalEnergies 's Gryphon decommissioning team, for achievements that have positively contributed to the health, safety, sustainability, and environmental performance across all TotalEnergies UK sites in 2025.
