Triton Knoll Offshore Wind Farm
Developer: RWE
Site Size: Covering an area of 134 m²
Site Location Triton Knoll is within the Greater Wash Strategic Area and is located off the east coast of England, approximately 20 miles off the coast of Lincolnshire and 28 miles from the coast of North Norfolk. Swell is predominantly North Easterly. Several beaches could be affected by the Array like Withernsea (81km), Mablethorpe (42km), Skegness (49km) and Cromer (68km).

Technology The proposed development will have an installed capacity of up to 1200 MW. The development proposal comprises the construction and operation of up to 288 wind turbine generators with a maximum tip height of up to 220 metres, offshore substations, meteorological stations and underwater cabling to connect the turbines and substations. The maximum annual electricity expected to be generated from the wind farm site is equivalent to the approximate domestic needs of up to 850,000 average UK households. Last Updated: 10/12/2013

Foundation concepts are classified under the following types:
• Monopile (steel and steel reinforced concrete) - Monopiles rely on the surrounding geology to provide lateral resistance to horizontal forces, such as wind on the turbine and waves on the support structure max diameter of 10.5m taking up a maximum area of 97m².
• Tripod; Jacket structures typically consist of three or four main legs which are linked by a supporting lattice of cross-braces. Each of the main legs may terminate with a sleeve through which a small diameter pile is driven and subsequently grouted or swaged (Figure 6.6). Jackets can also be ‘pre-piled’ by being located on and grouted or swaged onto pre- installed piles, or alternatively with suction buckets under each jacket leg.
• Multipile or jacket foundations -
• Gravity base- A gravity base structure (GBS) is a large diameter steel, concrete or steel and concrete combination base which sits on the seabed to support the turbine tower. The indicative diameter of the gravity base is 45m maximum with a seabed area take of 1590 m².
• Suction bucket monopod
Development Stage: Triton Knoll is now in the post-decision stage. The secretary of state granted development consent on 11/07/2013.
