Normandie 1 contract

Cable laying offer

Fugro is expanding its range of services with the addition of a cable-lay spread onboard the Fugro Saltire. The spread comprises a reel drive system to store the cables, a tensioner to lay them, twin winches and a quadrant deployment system on rails. In operation the cables are initially pulled into the base of the wind turbine generators and then laid along the seabed using a dynamic positioning system to line themupaccurately with the destination WTG. They are pulled in using the quadrant system to manage the cable during over-boarding and pull-in. The initial concept for the new cable-lay capability was developed during trenching operations at the Humber Gateway offshore wind farm, when E.ON asked Fugro to investigate laying cables from the Saltire . Fugro’s engineers fitted the cable-lay equipment in six weeks, and cable-laying was completed by February 2015. “As well as trenching 77 array cables, we installed eight array cables along with second end pull-ins of cables already laid by other contractors,” said Mike Daniel, trenching business line manager, Fugro Subsea Services.

Prysmian Group has been awarded a contract by Jersey Electricity plc for the Channel Islands’ Normandie 1 project. The project involves the turnkey supply and installation of a high voltage alternate current cable connection from France (Surville) to Jersey. The single-length 90kV 3-core cable will stretch for 28km. Prysmian will provide design, supply and commissioning of the submarine and land cable connections as part of a larger contract awarded to the consortium between Prysmian and VBMS. VBMS will perform the marine cable laying operations, including protection and landfall activities. The submarine cable will replace an existing, but obsolete, Normandie 1 interconnector, and its 100MW capacity will be shared by Jersey and Guernsey islands under the CIEG (Channel Islands electricity grid) partnership agreement. The submarine cables for the Normandie 1 linkwill beproduced in theArcoFeliceplant (Italy), the group's center of technological and manufacturing excellence. Project completion is scheduled for October 2016.
