We are thrilled to announce yet another collaboration with Equinor, this time for a subsea tie-back of Eirin Gas Field. A EPCI contract for the Eirin subsea tie-back development, with an option for a new gas solution from Troll B via the exisiting Kvitebjørn export pipeline.

The scope covers installation of structures, flexibles, umbilical, seabed rectification, tie-ins, and commissioning. It also includes design, fabrication, and installation of GRP covers and spool bringing important gas volumes to the European market.

Equinor has awarded Ocean Installer an EPCI (Engineering, Procurement, Construction & Installation) contract for the Eirin subsea tie-back development. In addition, the award also constitutes an option for a new Gas Export solution from Troll B via the existing Kvitebjørn export pipeline. Engineering will commence immediately and both projects are planned completed by 2025, bringing important gas volumes to the European market.

Eirin is a gas field in the North Sea that was originally discovered in 1978 and that now will be developed with a 2-slot Template with an integrated manifold where the well stream will be connected to the existing Gina Krog platform through a 9.5 km flexible flowline and Integrated Service Umbilical.

The optional scope on Troll B includes a new 2.5km flexible flowline from an existing PLEM (Pipeline End Manifold) on Troll B to a new PLEM close to the Kvitebjørn Hot-Tap. A rigid spool will also be fabricated and installed between the new PLEM and the Kvitebjørn Hot Tap.

– It is great to see that Equinor and its partners continue to develop and invest in the Norwegian Continental Shelf and that they once again put their trust in Ocean Installer to help them realize fast track projects like Eirin and potentially Troll B Gas Export.
