Award for Subsea Tie-back Project
DeepOcean, a Norwegian ocean services provider, has secured a contract to deliver subsea construction and tie-in services for a field development on the UK Continental Shelf, with the project being developed as a subsea tieback to an existing host facility.
The awarded scope includes installing a flexible production riser, a flowline, and an umbilical that will connect the host facility to a subsea tree.
The contract also covers the protection of the flowline and umbilical, in addition to commissioning the newly installed infrastructure.
Engineering and project management for this subsea construction and tie-in work will be spearheaded by the company’s Aberdeen office.
According to the company, the offshore operations will be carried out in two phases.
The initial phase will involve subsea construction and tie-in activities, followed by commissioning using a second offshore construction vessel from DeepOcean’s chartered fleet.
DeepOcean UK managing director Robin Mawhinney said:
“We are delighted to announce the award of this subsea tie-back project.
“This award acknowledges our significant track record in subsea construction and, at a time where there is a huge focus on homegrown energy solutions, we are proud to support our client with our specialist engineering, operational excellence and delivery certainty to realise this key project for the life extension of the existing infrastructure.”
In a recent development, DeepOcean won a contract from Equinor for subsea construction and installation works on the Snorre export and import gas project (SNEIG), with offshore operations planned for 2026.
The SNEIG project is part of the broader Snorre expansion, which is designed to extend the operational life of the Snorre oil and gas field beyond 2040.
The field area was discovered in 1979 and has been in production since 1992.
Last month, DeepOcean partnered with TotalEnergies, Equinor, Aker BP, Tenaris and LS Cable & System to introduce a new subsea flowline heating technology called FlowHeat.
FlowHeat is designed to reduce manufacturing and installation expenses by up to 35% and lower carbon emissions by 30% by separating the pipeline and heating installation processes.
