These are destined for WPD's 288MW Butendiek offshore wind farm planned in the Deutsche Bucht, 32 kilometres west of the German North Sea island Sylt. Water depths vary between 17 and 22 metres.
BN Offshore commercial manager Edwin van de Brug said that pile and transition piece design activities commence immediately, with foundation manufacture planned for 2012 and installation in 2013.
The company will employ its huge 100-metre high floating vessel HLV Svanen for foundation installation. The Svanen is currently employed at London Array after the placing of 51 monopile foundations at Walney 2 in the Irish Sea. Van de Brug: 'Our track record with the Svanen is 227 foundations, of 282 foundations in total.'
Siemens will deliver the 3.6MW turbines.
