Ocean Installer have been chosen by Equinor and its partners in the Troll A license as the SURF Contractor for their new 12 billion NOK investment in the Troll Phase 3 – Stage 2 Project. This SURF EPCI contract, worth over 1 billion NOK, includes a substantial fabrication scope and offshore work over three years, with the first campaign beginning in 2025.

Ocean Installer has also secured a separate contract for replacing a 4km 10” flexible flowline at the Troll B field in 2025.

Stage 2 of the Troll Phase 3 project includes eight new wells from two new templates with subsea controls extended from existing templates. A new 36” gas flowline will be laid as a tie-back to the Troll A platform, and the project will also perform modification work on Troll A.

The EPCI contract for Ocean Installer covers fabrication & installation of four large pipeline termination structures for the 36” gas flowline, five 20” spools, subsea pig launcher and receiver (PLR), 6km of 4.5” MEG Line and protection covers. The work also covers installation of the Subsea Production System and Umbilicals from OneSubsea. Trenching and pre-commissioning is also part of the scope of work.

Engineering work has already started from Ocean Installer’s offices in Stavanger and Oslo. The majority of the fabrication will be awarded to Norwegian subcontractors.

– The Troll Phase 3 – Stage 2 project is a perfect match with our capabilities, and we are excited to deliver this project in close collaboration with Equinor and our locally based fabrication partners. This award shows that our clients continue to rely on us for large, complex and production critical projects. Moreover, the Troll B Flowline Replacement award demonstrates the range of projects we can help our clients with – from big EPCIs to smaller T&I projects, says Ocean Installer CEO Kevin Murphy.
