Ocean Installer has signed an amendment with Statoil for riser replacement operations at the Troll C field in the North Sea, offshore Norway.
The deal includes options for work at the Vigdis field. The work will be executed under the SLMP Marine Installation Contract, the company said.
“We are extremely pleased to have secured more work at the Troll field as the Norwegian Continental Shelf continues to be an area of great importance to us. Following up from our success on the highly complex SIMOPRO operations for Statoil in 2015, this new award allows us to further reinforce our great cooperation with Statoil,” says Ocean Installer CEO Steinar Riise.
The work scope at Troll C includes recovery and installation of the oil export riser and two production risers. This work requires subsea and topside disconnection and removal of existing risers, and subsea tie-in and topside pull-in of new risers. Optional work includes flexible jumper replacement operations at the Vigdis field as well as other subsea operations.
Ocean Installer will use its construction support vessel (CSV), Normand Vision. The Troll C field is located in Blocks 31/2, 31/3, 31/5 and 31/6 of the North Sea approx. 80km west of Bergen at a water depth at of approximately 338m. The Troll C facility is also utilised for production from the Fram field. The Troll C work scope will take place in Spring/Summer 2016.
