ABB has won an order worth around $55 million to supply a submarine alternating-current (AC) power cable system for the 400 MW Dudgeon offshore wind farm, located off the coast of Norfolk, U.K. Dudgeon Offshore Wind Ltd., a company owned by Statoil and Statkraft, placed the order, and the underwater cables will feed the electricity generated by the project into the U.K. national grid.
The project's turbines will be situated in waters 18-25 meters deep and 32 km off the coast of the seaside town of Cromer. ABB says it will design and supply two 132 kV, three-core AC submarine cables, each 42 km in length, running from the wind farm's offshore substation to Weybourne Hope, where they will connect to the onshore cables. The cables will be manufactured at ABB's factory in Karlskrona, Sweden, and delivery will commence in 2016.
"Offshore wind is a growing renewable energy resource, with Europe accounting for around 70 percent of new offshore wind generation capacity," says Claudio Facchin, head of ABB's Power Systems division. "Transporting electricity from offshore wind farms to the shore and then integrating it into the grid for supply to consumers are key elements."
Bjorn Ivar Bergemo, asset manager of the Dudgeon project, adds, "The submarine export cable connection is a long-lead item, and placing this contract represents a major milestone in the development of the Dudgeon project."
