Latest event on Sandbank

Vattenfall and Stadtwerke München (SWM) officially put the offshore wind farm Sandbank into operation by organizing a public barbecue in the city park (Stadtpark) of Hamburg. The “wind power barbecue” resembles the aim of Vattenfall and SWM to make the diverse usage possibilities of climate friendly electricity of the North Sea more tangible: For example, the conversion of electricity to heat on an electric grill.

Project Details for Sandbank
General Information Name Sandbank correct
Other names Sandbank24 correct
Country name Germany correct
Region Exclusive Economic Zone 2 (SylWin) (BSH Cluster 5 in Draft Network Plan) correct
Comments It is expected the wind farm was downsized to 288MW because of the remaining connection capacity left in the SylWin1 converter station (exactly 288MW).

Previously the site was expected to comprise of 96 turbines: 80 x 3.6MW in the large geographical section to the north and 16 x 4MW in the smaller east-west slither to the south - the area known as Nördlicher Grund (not to be confused with a different project of the same name). It is worth noting that the Nördlicher Grund slither is not now expected to be developed. Before this announcement, Sandbank obtained consent for 96 turbines to a maximum output of 576MW.

Consequently the project is expandable and according to Vattenfall could reach a maximum capacity of approximately 500 megawatts. 64 additional turbine locations are available, of which 24 (including all of the southern slither) have already been approved.

Export Cables
Please note that export cables connect the offshore transformer (substation) to either; shore or an offshore HVAC-HVDC converter station for onward transmission via HVDC cabling. Please see the converters page for planned converter stations and transmission cables.

The export cable length does not generally include the onshore component. The exception is when the onshore substation is close to shore.

Comments Each string will link a total of nine turbines, with every two strings connected to one another in order to ensure operation of the turbines even in the case of cable damage. A total of 76 cables connect the 72 Siemens SWT-4.0-130 turbines. To begin with, the cables are placed on the seabed and later injected at a minimum burial depth of 0.6m (although some may be buried at just over 1m depth).To begin with, the cables are placed on the seabed and later injected at a minimum burial depth of 0.6m (although some may be buried at just over 1m depth). correct
