PARIS -- Subsea 7 has contracted Nexans to provide static subsea electro-hydraulic control umbilicals for Total’s Laggan-Tormore gas/condensate project, 125 km (77.7 mi) west of Shetland.

Nexans will design, engineer, and manufacture 143 km (88.8 mi) of umbilicals, which will integrate steel tubes for fluids, 3 kV power cables, and fibre optic cables. It will perform the work at its facility in Halden, Norway, with delivery due early next year.

The project’s subsea production system will feature two production template-manifolds. The system will be controlled by two Nexans umbilicals linking the Laggan and Tormore fields over a distance of 17 km (10.6 mi), and then a further 126 km (78 mi) to the shore of the main Shetland Island.

This will be one of the world’s longest umbilicals, the company claims. Ragnvald Graff, sales and marketing director, Energy Business, said: “We have the proven capability to deliver sophisticated umbilical systems capable of operating over long distances in similarly demanding conditions, such as in the Snøhvit and Ormen Lange projects on the Norwegian continental shelf.”
