RWE npower renewables has awarded a multi-million pound contract to UK firm Global Marine Systems to install offshore export cables at Gwynt y Mor offshore wind farm, North Wales.
At 576 MW, Gwynt y Mor will be one of the largest offshore wind farms currently in construction, and is being built by RWE npower renewables. The project is a shared investment between partners RWE Innogy, Stadtwerke Munchen and Siemens.
Once fully operational, energy generation from Gwynt y Mor is expected to be equivalent to the average annual needs of around 400 000 homes.
The offshore wind farm is being constructed 13 kilometres off the North Wales coast, in water depths of 12-28 metres, and was granted approval by DECC (Department of Energy and Climate Change) back in December 2008.
Global Marine Systems Energy, the energy unit of Global Marine Systems Ltd, was selected to carry out the subsea cable installation, on the basis of its historical track record of successful cable installation and the significant amount of work within the offshore windfarm market over the past ten years.
Construction of the EUR2bn ($2.6bn) Gwynt y Mor project began in November 2009 when work to prepare land at St Asaph for the construction of a new 132/400kV substation was carried out by North Wales civil engineering company Jones Bros.
Turbine foundation installation is expected to start in the fourth quarter of 2011, and is expected to last for approximately two years. Offshore export cable installation is due to commence in 2012, with Global Marine already involved in the planning and preparation of activities for the project.
