Beatrice Field Location: Offshore Ross-shire Operator: Talisman Energy (UK) Ltd Configuration: 2 X 5-MW 5M Operation: 2007 WTG supplier: REpower EPC: AMEC, REpower Quick facts: In Apr 2005, Talisman Energy and Scottish and Southern awarded AMEC a contract to design and manage delivery of two 5-MW wind turbines for the Beatrice wind farm demonstration project. The scheme demonstrates the feasibility of siting WTGs in deepwater (45m in this instance) at a site 25km offshore and 70km northeast of Inverness in the Beatrice oil field. The first WTG was set in August 2006 and came online in May 2007 with the second following in Aug. Photograph courtesy of

Burbo Bank Location: Lancashire Operator: Dong (UK) Ltd Configuration: 25 X 3.6-MW 3.6/107 Operation: 2007 WTG supplier: Siemens Wind Quick facts: These machines were erected in less than 1.5mos at a site 12km offshore Wallasey in Liverpool Bay, well ahead of schedule. During construction, Siemens leased a 45,000 m² site at Mostyn in North Wales. The 65m steel towers were assembled upright and all systems were tested before they were loaded onto the installation vessel which carried towers, nacelles, hubs and blades for 3 turbines per trip to the site area. Each 500t wind turbine was erected in five heavy lifts with a maximum weight of approximately 185t. The average erection time per turbine was less than half a day. Photograph courtesy of

Gunfleet Sands Location: Norfolk Operator: Dong Energy UK Configuration: 48 X 3.6-MW SWT-3.6-107 Operation: 2010 WTG supplier: Siemens Wind Power EPC: Dong Energy, MT Højgaard Quick facts: Gunfleet Sands is 7km off the Essex coast opposite Clacton-on-Sea and the subsea cable connection makes landfall just northeast of Holland-on-Sea. The project was first identified in 1996 by Windmaster Developments, acquired by Enron in 2000, purchased by GE in 2002, and then purchased by Dong Energy. Final consents were awarded in Mar 2004 for Phase-I and in Mar 2008 for Phase-II. The turbines are spaced a 435m and the turbine rows are about 890m apart. The total surface area of the site is approximately 15km². The maximum height of the blade tip above sea level is 129m. Due to the very varying water depths the installation was carried out by the use of the large floating crane "Svanen" and the jack-up barge "Excalibur". Photograph courtesy of Osprey Shipping Ltd |
