DeepOcean has secured a contract to support the decommissioning and removal of a floating production, storage and offloading vessel in the UK North Sea, adding another major assignment to its growing decommissioning portfolio.
The ocean services specialist will carry out subsea disconnection work and support the vessel’s tow to shore as part of a wider recycling project for an FPSO currently operating on the UK continental shelf.
Managed from the company’s Aberdeen base, the campaign will cover a broad scope of offshore activities, including hydrocarbon and chemical flushing, isolation and disconnection of subsea trees, manifolds and pipeline systems, as well as the removal of risers, umbilicals and mooring infrastructure.
DeepOcean will also oversee preparations for the FPSO’s departure from the field and subsequent tow to a recycling facility.
The contractor plans to execute the work using methodologies and specialist tooling developed during previous FPSO decommissioning campaigns in the region.
According to DeepOcean, the operation will build on techniques deployed during the removal of the Gryphon Alpha FPSO in 2025, allowing the entire offshore scope to be completed without the use of divers.
