Dec 3, 2014 - Norfolk-based firm Subsea Protection Systems Ltd (SPS) has commenced shipping concrete mattresses to Vattenfall AB for its 49.5-MW extension of the Kentish Flats offshore wind farm in UK waters.
The Swedish utility said in a statement on Tuesday that SPS will supply 255 concrete mattresses that will protect cables used by the existing 90-MW wind park and allow the overlaying of new ones. The Norfolk firm is being subcontracted by Bohlen & Doyen, which acts as Vattenfall’s main offshore electrical contractor for the project. The value of the contract was not given.
The extension, which is worth some GBP 165 million (EUR 258m/EUR 209m), will add 15 turbines of 3.3 MW each to the existing 30 machines of the wind farm off the Kent coast. All turbines are seen to be installed by August 2015 and first power would be generated in early September. The completion of the entire project is scheduled for December 2015.
The Kentish Flats Extension will be able to produce enough electricity in a year to cover the annual power consumption of about 35,000 homes, Vattenfall noted.
