DeepOcean has completed subsea construction and tie-in work at the Teal West development on the UK Continental Shelf for Anasuria Operating Company
Teal West is an offshore oil and gas development project in the Central North Sea, on the UK Continental Shelf. The field has been developed as a subsea tieback to the existing Anasuria floating production, storage and offloading (FPSO) facility.
DeepOcean’s work included installing a flexible production riser and flowline, together with an umbilical connecting the Anasuria FPSO to the Teal West subsea Christmas tree. The company also had to protect the flowline and umbilical and commission the newly installed infrastructure.
Richard Beattie, CEO of Anasuria, said, “Teal West is an excellent example of what can be achieved when operators, contractors and service companies work together towards a common goal. At a time when our industry faces significant uncertainty, projects like this showcase the expertise, innovation and collaboration that continue to underpin the UK North Sea. DeepOcean has been a trusted partner throughout the development, helping to deliver a successful subsea tie-back that maximises the value of existing infrastructure. Projects like Teal West highlight the important role that existing infrastructure can play in supporting secure domestic energy production, sustaining skilled jobs and delivering long-term value from the UK North Sea.”
The operation was executed using a remotely operated vehicle (ROV) combined with specialised tooling, replacing the need for diver intervention. DeepOcean’s tie-in tool performs diverless connections for high-pressure flanges, enabling the connection of pipes and valves using subsea robotics.
Robin Mawhinney, EVP EMEA at DeepOcean, said, “We’re proud to have supported Anasuria in the successful delivery of the subsea scope of Teal West development and would like to congratulate the team on bringing the field onstream. The project demonstrates the strength of our integrated engineering and offshore execution capabilities and the important role subsea tie-backs play in maximising the value of existing offshore infrastructure.”
The field development contains two production wells and a water injection well. Initially, one production well will be connected to the Anasuria FPSO via 3km of subsea flowlines. The Anasuria FPSO is situated 180km east of Aberdeen at 90m of water depth.
DeepOcean’s Aberdeen office led the engineering and project management for the subsea construction and tie-in scope of work.
Offshore operations were executed in a phased approach, with subsea construction and tie-in activities completed first, followed by commissioning performed by a second offshore construction vessel from DeepOcean’s chartered fleet.
