LUXEMBOURG – Total E&P Norge has awarded Subsea 7 (Oslo Børs:SUBC) an $800-million subsea, umbilical, riser, and flowline (SURF) contract for the Martin Linge gas field development. The location is 180 km (112 mi) west of Bergen in the Norwegian North Sea.

Subsea 7 will provide engineering, procurement, construction, and installation of the full subsea spread. These will comprise a 160-km (99-mi) power cable from the Martin Linge platform to Kollsnes; a 70-km (43-mi) export pipeline and associated valve structures, umbilical, and spools for the gas export system; a 55-km (34-mi) fiber-optic cable; and a 3-km (1.8-mi) pipeline and riser system from the Martin Linge platform to the floating storage unit.

The scope extends to transport and installation of the mooring system for the FSU. Subsea 7 will deploy various pipelay, construction, diving, plowing, trenching, and survey vessels. Its newest flagship vessel, Seven Borealis, will install the gas export pipeline.

Engineering and project management are under way at Subsea 7’s Stavanger office. Offshore operations should start in spring 2014. The contract duration is about four years.
