Subsea Integration Alliance wins EPCI contract for Hasselmus project

Subsea Integration Alliance, a partnership between Subsea 7 and OneSubsea, has secured an engineering, procurement, construction, and installation (EPCI) contract by OKEA for the Hasselmus project in the southern Norwegian Sea.

The contract covers the EPCI of the subsea production systems (SPS) and subsea pipelines (SURF) for a single subsea well with direct tie-back to the Draugen production platform.

The SURF scope comprises approximately nine kilometers of pipe-in-pipe flowline and associated structures in water depths of approximately 250 meters.

Project management and engineering will commence immediately at Subsea 7’s offices in Stavanger, Norway.

Fabrication of the pipelines will take place at the company’s spool base at Vigra, Norway, and offshore operations will be executed in 2022 and 2023. 

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

“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. We look forward to continuing to support this objective for the Hasselmus project.”

The Hasselmus gas discovery is located on the western edge of the Trøndelag platform, seven kilometers northwest of the Draugen platform, in production license 093.

OKEA has 44.56% working interest in the Draugen license and the Hasselmus project, while Petoro holds 47.88% and Neptune Energy Norge the remaining 7.56%.

The companies reported at the beginning of June that they had made the decision to develop the Hasselmus gas discovery as a subsea tie-back to the Draugen platform.
