Dudgeon Offshore Wind Limited awards cable installation contract

Dudgeon Offshore Wind Limited has announced a further contract associated with the construction of the Dudgeon Offshore Wind Farm, located 20 miles off the coast of North Norfolk.

The Export Cable Installation (EPCI) contract for inter array cables and the installation of the submarine export cables for the wind farm has been awarded to Visser & Smit Marine Contracting B.V. [VSMC]. The contract, the value of which is €110m, covers the engineering, procurement, construction and installation of the inter array cables as well as the installation of the submarine export cables.

VSMC will start in 2015 by performing two 1,100 m horizontal directional drillings at the landfall followed by the installation of two 42 km export cables in 2016. The work also includes the design, supply, installation, terminations and testing of 67 inter-array cables with the total length of approximately 100 km.

The export cable will be loaded on to a cable installation vessel in Karlskrona, and will be laid between pre-drilled ducts in the landfall area and from there, towards the offshore substation. They will be protected by means of a ploughing technique.

The inter array cables, which will be installed between the 67 turbines foundations will be pulled in for hang-off and termination inside the monopole foundations. The contract also includes burial of the cables.

When fully operational, the Dudgeon Offshore Wind Farm will have an installed capacity of 402MW. This equates to enough energy to power up to approximately 410,000 homes and reduces emissions of carbon dioxide by up to 19 million tonnes over its 25 year lifetime, providing 0.5 per cent of the UK’s overall annual electricity needs.
