BMT Argoss, a subsidiary of consultancy company BMT Group, announced on Monday that it has completed a comprehensive evaluation of meteorological and oceanographic environmental conditions for the Total-operated Martin Linge field in the Norwegian sector of the northern North Sea.

BMT’s assessment included the installation routes of associated subsea assets; a submarine power cable to Kollsnes, Norway, across the Norwegian Trench via the Troll field; a fibre-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 AS in the region.

To provide power to the Martin Linge field from the Norwegian mainland electrical grid, Total selected a new 170 km long subsea cable - the world’s longest alternating current (AC) power line from shore to an offshore platform.  The submarine power cable running between Martin Linge and Kollsnes crosses the Norwegian Trench that reaches its deepest (approximately 300 m) in the vicinity of the Troll field.

The Martin Linge gas field is situated between Norwegian Licence Blocks 30/4 and 30/7, approximately 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.
