Producer Equinor said Sept. 10 it and supplier Saipem SpA completed the installation of a 36-inch oil pipeline extending 283 kilometers from the Mongstad oil terminal outside Bergen to the riser platform at the Johan Sverdrup field in the North Sea.
The vessel Saipem Castorone began pipe-laying operations at Mongstad in late April. With the oil pipeline installed, Saipem Castorone is preparing to lay the 156-kilometer gas pipeline that will extend from the Johan Sverdrup field to the Statpipe pipeline. Gas from the field will be shipped to Kårstø. The pipeline installation operations are expected to be completed during the autumn.
The pipeline marks the end of the current year's installation campaign when three jackets, two topsides, one bridge, over 400 kilometers of pipelines and 200 kilometers of power cables were installed. In 2019 the last two topsides and remaining bridges will be put in place before startup of the first phase of the Johan Sverdrup development, expected in November 2019.
