BMT completes environmental study for Total Norge in North Sea
LONDON -- BMT ARGOSS, a subsidiary of BMT Group, has recently completed a comprehensive evaluation of meteorological and oceanographic environmental conditions for the Martin Linge field in the Norwegian sector of the northern North Sea.
BMT’s assessment also included the installation routes of associated subsea assets, including a submarine power cable to Kollsnes, Norway, across the Norwegian trench via the Troll field; a fiber optic network to Huldra; and a pipeline to the TP1 tie-in point. This work was an extension of MetOcean studies previously performed by BMT for Total Norge in the region.
The Martin Linge gas field (formerly known as Hild) is situated between Norwegian license blocks 30/4 and 30/7, midway between the Shetland Islands and the Norwegian coast, in approximately 115 m water depth. The Huldra and TP1 sites are in equivalent water depths and a spatial review of the western study area was completed to check the validity of using the Martin Linge Criteria at these three sites.
To provide power to the Martin Linge field from the Norwegian mainland electrical grid, Total selected a 170-km long subsea cable, the world’s longest alternating current power line from shore to an offshore platform. The submarine power cable running between Martin Linge and Kollsnes crosses the Norwegian Trench, which reaches its greatest depth at approximately 300 m.
The study involved a collation of existing BMT and third-party reports, as well as new analyses, to evaluate both extreme design and typical (ambient) operational conditions, in order to provide a single, comprehensive study for the development project.
