E.ON has put in the electrical offshore transformer station of the 385 MW Arkona offshore windfarm within the German Baltic Sea.
The station has been efficiently put in at a water depth of just about 30 meters, 35 kilometres northeast of the island of Rugen.
Moving the topside from a barge onto the inspiration with the crane ship Oleg Strasnov marked the set up of the world’s heaviest alternating present platform, which had beforehand been lifted in a single block out at sea.
The largest single part of the €1.2bn undertaking, the transformer weighs greater than 5000 tonnes and consists of the jacket basis anchored within the seabed and the topside with switchgear and transformers.
It is the dimensions of an eight-storey constructing and has a helipad at an altitude of 70 metres above sea degree. The building of the transformer station on the French shipyard STX required greater than 500,000 working hours.
The Arkona windfarm is a three way partnership between E.ON and Statoil who will use the platform with the transmission grid operator 50Hertz. It will export energy to the grid by way of the 93km Ostwind 1 cable system and 50Hertz’s onshore substation in Lubmin.
The unmanned station is positioned in the course of the development website of the windfarm and can bundle the electrical energy produced by 60 of Siemens’ 6 MW wind generators, which is then transported to the mainland by sea cable.
The substation is operated from the working station of the windfarm within the port of Mukran Port in Sassnitz on Rugen island, whereas E.ON’s Offshore Marine Coordination Centre in Hamburg displays and controls the operation.
The subsequent step within the building part would be the laying of the inner parking cabling. This will probably be adopted in late summer time by the set up of the wind generators on the foundations. The full commissioning of your complete windfarm is deliberate for 2019.
