CT Offshore has completed the installation of 54 of the 108 cables on the 389MW West of Duddon Sands offshore wind farm, which will feature 108 Siemens 3.6MW wind turbine generators in the East Irish Sea, located around 14km from the nearest coast on Walney Island, Cumbria.
CT Offshore’s CLV SIA vessel installed the 54 cables, while two A2SEA-owned installation vessels, Swire Blue Ocean’s Pacific Orca and the Sea Installer completed the construction of 54 monopile foundations for the project in August 2013.
The project, a 50/50 joint venture between ScottishPower Renewables and Dong Energy, calls for the construction of foundations, wind turbines, export and array cables, offshore and onshore substations, grid connection in Heysham, Lancashire and O&M facilities in Barrow-in-Furness.
Having already started work on onshore construction, the developers began offshore work in 2013 and expect to complete the total project by late 2014.
As part of the offshore construction, the developers have already installed an offshore substation, which is placed within the 67km² site and will be connected to the 108 turbines through a series of inter-array cables.
VSMC was awarded the installation of the two export cables, while Bladt is providing the 108 steel monopiles and transition pieces that are being manufactured in Denmark.
RES Offshore will provide EPC services to design and install a power performance met mast for the project that will record weather data to support the construction and operational activities.
In June 2011, Siemens was selected to supply 108 3.6MW, 80m high wind turbines with a separate maintenance contract for a five-year warranty of the turbines from the start of their operations.
DONG Energy installation manager Lars Bruun said that the teams of developers and CT Offshore have worked together to achieve the halfway mark with the installation of 54 cables.
"Our WoDS project team is very content with CT Offshore´s cable installation performance to date. They have been proactive, shown initiative and professionalism in their performance, which is reflected in the quality of the cable installation work up to now," said Bruun.
