OKEA has awarded Subsea Integration Alliance, a partnership between Subsea 7 and OneSubsea, a contract to provide subsea equipment for the Hasselmus project in the Norwegian Sea.

The contract is estimated to cost between $50m and $150m. It will see the engineering, procurement, construction, and installation (EPCI) of the subsea production systems (SPS) and subsea pipelines (SURF) for single subsea well.

OKEA plans to develop this well as a direct tie-back to the Draugen production platform. The Hasselmus project is located 7km north-west of the Draugen platform.

The SURF scope comprises approximately 9km of pipe-in-pipe flowline and associated subsea structures.

Subsea 7 plans to immediately commence project management and engineering work at its offices in Stavanger, Norway.

The pipelines are planned to be fabricated at the firm’s spoolbase at Vigra, Norway, while the offshore operations are scheduled to be executed in 2022 and 2023.

Subsea Integration Alliance CEO Stuart Fitzgerald said: “This award to Subsea Integration Alliance supports our strategy for early engagement, full subsea system delivery, and our track record with OKEA.

“Working in partnership with OKEA has supported optimised solutions, early decision making and shortened delivery time, ultimately improving cost efficiency throughout the entire field lifecycle.”

OKEA operates the Draugen licence and the Hasselmus project with a 44.56% stake. Other partners include Petoro (47.88%) and Neptune Energy Norge (7.56%).

Separately, OKEA awarded a contract to Aker Solutions to provide new equipment required to modify the Draugen platform to enable gas processing from the Hasselmus discovery.

This sizable contract is worth between $23.2m (Nkr200m) and $81.3m (Nkr700m).

The contract involves hook-up of the new riser, an inlet arrangement with an electrical heater, valve arrangement, revamp of gas export compressors, inlet scrubber, and modifications of the condensate train.
