Offshore construction at
the Westermost Rough offshore wind farm has completed its next significant
milestone with the successful installation of the project’s offshore substation
on site in the North Sea. The vessel Stanislav Yudin has safely lifted
the offshore substation into position, and work is now underway to pull in and
connect the pre-laid export cable to the substation platform.
Westermost Rough will consist of
35 wind turbines with a total installed capacity of 210MW, and is due to be
fully completed in 2015. Monopile foundation installation was completed in late
May, with turbine installation due to begin in late summer.
The offshore substation was
fabricated in STX France's St Nazaire shipyard, making use of facilities and
techniques well proven for building cruise ships. The substation consists of two
major sections - the jacket foundation which is fixed to the sea-bed, and the
topside which sits on the jacket foundation and houses the electrical equipment
and necessary support systems.
The contract to fabricate the
substation was awarded in late November 2012. Installation contractor Seaway
Heavy Lifting performed the installation operation.
Duncan Clark, Programme Director
for Westermost Rough at DONG Energy said:
“It has been a very busy and
exciting time for the everyone involved in the project with the successful
installation of the export cable, all the monopile foundations and the offshore
substation platform. This continues now with our work alongside National Grid to
energise the onshore electrical systems, and with Technip to install the array
cables. These are very complex operations and major engineering achievements so
the whole project team is delighted that we have safely completed these major
milestones along the road to having the wind farm fully up and running in
substation is positioned within the 35km² site and will be linked to the 35 6MW
turbines via a series of inter-array cables. At the offshore substation, the
voltage from the turbines is increased and the export cable will then take the
electricity ashore where the wind farm is connected to the UK national grid at
Salt End, near Hull.
Westermost Rough Offshore Wind Farm is jointly owned by
DONG Energy, Marubeni Corporation and the UK Green Investment Bank. The project
marks the first time that the Siemens 6MW turbine will be used on a commercial
scale anywhere in the world. Find out more about DONG Energy and the Westermost
