Wind Energy Power Plants in the UK - offshore
Beatrice Field
Location: Offshore Rossshire
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.

Burbo Bank
Location: Offshore Lancashire
Operator: Dong (UK) Ltd
Configuration: 25 X 3.6-MW SWT-3.6-107
Operation: 2007

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 mē 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.

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".
