Athena Decommissioning Works – DOF Subsea Wins Key Contract

DOF Subsea, a leading provider of integrated subsea services, has been awarded a contract by Ithaca Energy for phase 1 of the decommissioning of the Ithaca Operated Athena Field in the UK North Sea. The scope of work includes removing the subsea water column infrastructure that has been used on the field.



The contract involves the removal of mid-water arch and risers, and secures utilisation of several DOF Subsea vessels, capable of undertaking both moorings and construction work, operating in the Atlantic region during Q4 2016 and will utilise vessels from DOF Subsea’s state of the art fleet. DOF Subsea UK has extensive fleet capability and unrivalled access to the vessels.

DOF Subsea has steadily built its track record in decommissioning projects in both the UK and Norwegian sectors. In recent years the company has seen activity increase with the growing focus in the North Sea.

UK Managing Director, Robert Gillespie, said “This is a very important project for us. Conditions in the industry are challenging, but the North Sea decommissioning sector is active and we are well positioned to deliver in this market. We have completed several decommissioning projects in recent years, and we are looking forward to working with Ithaca Energy on this scope.”

“Project management and engineering are established strengths at DOF Subsea, enabling us to provide a full decommissioning service to a high standard. In everything we undertake, our teams are dedicated to efficient and safe operations, consistently delivering the best results for our clients.”

Athena is located in UK Continental Shelf block 14/18B in the central North Sea (Outer Moray Firth area) at a water depth of 130m. Ithaca ceased production from the Athena field in January 2016, with the FPSO departing the field in February 2016.
