(WO) — DeepOcean has completed subsea construction and tie-in work for Anasuria Operating Company’s Teal West development in the UK North Sea, connecting the field to the existing Anasuria FPSO.
DeepOcean’s scope included installation of a flexible production riser and flowline, along with an umbilical connecting the FPSO to the Teal West subsea Christmas tree. The company also completed protection and commissioning of the newly installed infrastructure.
The tie-in was executed using a remotely operated vehicle (ROV) and specialized tooling, eliminating the need for diver intervention. DeepOcean used its proprietary tie-in tool to perform high-pressure flange connections using subsea robotics.
Teal West is located in the Central North Sea and has been developed as a subsea tieback to the Anasuria FPSO, approximately 180 km east of Aberdeen in about 90 meters of water.
The development comprises two production wells and one water injection well. Initially, one production well is being connected to the FPSO through approximately 3 km of subsea flowlines.
“Projects like this showcase the expertise, innovation and collaboration that continue to underpin the UK North Sea,” said Richard Beattie, CEO of Anasuria. “DeepOcean has been a trusted partner throughout the development, helping to deliver a successful subsea tie-back that maximizes the value of existing infrastructure.”
The project demonstrates the strength of our integrated engineering and offshore execution capabilities and the important role subsea tiebacks play in maximizing the value of existing offshore infrastructure,” added Robin Mawhinney, EVP EMEA at DeepOcean.
DeepOcean’s Aberdeen office led engineering and project management for the subsea construction and tie-in scope. Offshore work was carried out in phases, with construction and tie-in activities followed by commissioning from a second offshore construction vessel in DeepOcean’s chartered fleet.
DeepOcean said the project has now been brought onstream, with the tieback extending the use of existing Anasuria infrastructure to support additional North Sea production.
