Ocean services provider DeepOcean has been selected to support the subsea decommissioning and disconnection of an FPSO in the UKCS.

The scope of work includes hydrocarbon and chemical injection flushing; isolation and disconnection of subsea trees, manifolds, and pipeline infrastructure; disconnection of risers and dynamic umbilicals; riser and mooring chain severance and recovery; and FPSO sail-away and tow to shore.

The project will be managed and executed by DeepOcean’s operations in Aberdeen.

Robin Mawhinney, Executive Vice President of DeepOcean’s EMEA region, said, “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.”

Gary Scott, Commercial Director of DeepOcean’s EMEA region, commented, “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 is a testimony to the team’s successful delivery of decommissioning scopes in the region.”
