Okea dishes out Hasselmus contracts off Norway
Norwegian independent Okea has awarded contracts for developing the Hasselmus gas discovery in the Norwegian Sea, after taking a final investment decision on the project last month, the contractors reported on July 2.
Subsea Integration Alliance, a partnership between Subsea 7 and OneSubsea, has obtained an engineering, procurement, construction and installation contract for the subsea production systems and pipelines for Hasselmus' single planned well, which will be tied back to the Okea-operated Draugen platform. The scope includes 9 km of pipe-in-pipe flowline and associated structures in waters 250 m deep.

Project management and engineering will begin right away at Subsea 7's offices in Stavanger, and fabrication of pipelines will take place at the company's spool base at Vigra. Offshore operations will be carried out in 2022 and 2023.
Meanwhile Aker Solutions has secured an engineering, procurement, construction, installation and commissioning contract for modifications at the Draugen platform so that it can process gas from Hasselmus. The scope covers hook-up of a new riser, a new inlet arrangement with an electrical heater, a new inlet scrubber, a valve arrangement, revamp of gas export compressors, and modifications of the condensate train.
Aker Solutons will also begin the work right away, undertaking prefabrication in Egersund, engineering, procurement and project management in Trondheim and Kristiansund and other services offshore. It expects to complete the work by the end of 2023.
Okea expects to recover 1.65bn m3 of gas from Hasselmus at a cost of 2.4bn kroner ($290mn). Production is slated to start in the fourth quarter of 2023 and reach a plateau of over 4,440 barrels of oil equivalent/day.
The company, backed by private equity group Seacrest Capital, operates the licence containing Draugen and Hasselmus with a 44.6% interest, while Petoro has 47.9% and Neptune Energy 7.6%.
