Ocean Installer has won subsea umbilicals, risers and flowlines contract for Equinor-led Troll phase 3 – stage 2 project.
The deal, worth over NOK1bn ($94.5m), includes a substantial fabrication scope and offshore work over three years, with the first campaign beginning in 2025.
The second stage of the Troll phase 3 project includes eight new wells from two new templates with subsea controls extended from existing templates. A new 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.
Ocean Installer’s work scope covers fabrication and installation of four large pipeline termination structures for the gas flowline, five spools, subsea pig launcher and receiver, 6km of MEG Line and protection covers. The company will also install the subsea production system and umbilicals from OneSubsea as well as trenching and pre-commissioning 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 company said.
Ocean Installer was acquired by offshore energy and marine services business Moreld from private equity group HitecVision earlier this month. The company has also secured a separate contract for replacing a 4km flexible flowline at the Troll B field in 2025
