Nexans, worldwide expert in the cable industry, has been awarded a contract by Subsea 7*, for the design, engineering and manufacture of a total length of 143km of static subsea electro-hydraulic control umbilicals for the Laggan-Tormore gas field development, 125km West of the Shetland Islands in the UK.
The umbilical product will integrate steel tubes for fluids, 3 kV power cables and fibre optic cables. The project will be carried out at Nexans’ specialised umbilical facility in Halden, Norway, with delivery scheduled for early 2012.
The subsea production system offshore will consist of two production template-manifolds. The system will be controlled by two Nexans static subsea electro-hydraulic umbilicals that will link the Laggan and Tormore fields over a distance of 17km and then a further 126km to the Shetland shore. The 126km umbilical will be one of the longest in the world.
“Subsea 7 is a very important customer for Nexans and we are very pleased to be working with them on this strategic project that will open up the West of Shetland for future development,” says Ragnvald Graff, Sales and Marketing Director, Energy Business. “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.”
Subsea 7 was awarded a contract for the Laggan Tormore field development in October 2010 by Total E&P UK Limited. Subsea 7’s principal scope of work comprises the engineering, fabrication and installation of 141km of 8-inch and 2-inch piggy-backed service pipelines and the engineering, supply and installation of 1 x 126km and 1 x 17km control umbilicals and associated subsea structures and tie-ins.
