Detailed electrical design for offshore substationfor the Walney 1 project in UK.
offshore <strong>Wind</strong> farm 29offshore substationsCOWI designs platform topsides and their concrete foundations. The platformitself houses the main transformer with associated cables and panels, internalpower supply, an emergency generator, a fire-fighting unit, a workshop andmonitoring and control system. The whole operation will be controlled andmonitored from the shore.Rødsand 2The wind farm comprises 90 offshore wind turbines with a total output of 207 MW,enough to supply 200,000 households for a whole year. Rødsand 2 also offersthe opportunity to build three trial wind turbines with a capacity of 15 MW intotal. The transformer platform will collect electricity from these wind turbinesand transform it from 33 kV to 132 kV for transferral via a powerful marinesubsea cable to the shore, benefiting domestic consumers and companies alike.Selected references››Detailed electrical design foroffshore substation for 207 MWwind farm Rødsand 2 inDenmark››Offshore substation detailedelectrical design of 34 kV and132 kV equipment as well asprotection relays.

The transformer alone weighs 280 tonnes. The ground planwill be 30 m x 16 m.The platform will be placed at a depth of six metres on aso-called “gravity-based” foundation, which retains its stability on the sea bed inall weather conditions by virtue of its own weight.34 kV switchgear in Walney 1 in UK.
