Equinor Energy AS has let a contract to ocean services provider DeepOcean to support the operator’s increased gas export project at Troll B in the northern part of the North Sea.
The project involves replacement of the current 15-in. gas export riser with a new 13-in. gas export riser at the Troll B floating processing and accommodation platform.
The contract scope includes engineering, transportation, and installation of the gas export riser, subsea tie-ins, and pre-commissioning support. DeepOcean has not disclosed the value of the contract.
Previously, DeepOcean has performed similar riser replacement operations at several Equinor-operated fields including Njord, Kristin, Troll C, and Åsgard.
Project management and engineering for the Troll B riser replacement will begin immediately at DeepOcean’s office in Stavanger with further support from the company’s Haugesund office in Norway. Offshore operations are expected to take place in 2024 using the Edda Freya installation vessel.
