GWYNT Y MOR Offshore Wind Farm Ltd. has secured a contract to begin the next stage of the construction of an offshore wind farm off the North Wales coast.
In a deal with Seaway Heavy Lifting Ltd. of Cyprus, a heavy-lift vessel called Stanislav Yudin will operate in Liverpool Bay between April and December of this year to install the major components of the 160-turbine wind farm.
The Stanislav Yudin, which has a lifting capacity of 2,500 metric tons and a fully revolving crane, will install the jacket foundations and topsides for the two offshore substations, along with 60 wind turbine foundations.
The vessel will install the first visible components of the wind farm. Beginning this month, there will be periods of intense offshore activity as the substations, foundations, monopiles and transitions pieces begin to appear more than 13 km off the North Wales Coast.
This agreement builds on an existing contract with Seaway Heavy Lifting announced in February 2011, under which the Stanislav Yudin will transport and install the offshore substation topsides being built at Harland and Wolff in Belfast, Ireland. Now, the Stanislav Yudin will also install 60 monopiles and transitions pieces, with an option of further foundations in the future.
The substation jackets, manufactured by BurntIsland Fabrication in Scotland, will be installed between April and June, followed by the installation of the foundations from July onwards.
At 576 MW, Gwynt y Mor is one of the largest offshore wind farms currently in construction in Europe. It is a shared investment between partners RWE Innogy, Stadtwerke MÃ¼nchen GmbH and Siemens. Once the project is fully operational, it is expected to supply the equivalent of the average annual electricity needs of approximately 400,000 households.
