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.
