Horns Rev 2's location in relation to the wind farms of the German Bight

Horns Rev 2 is an offshore wind farm located on Horns Rev (Horns Reef) in a shallow area in the eastern North Sea, about 30 km (19 mi) off the westernmost point of Denmark, Blåvands Huk. When inaugurated in 2009, Horns Rev 2 was the largest offshore wind farm in the world until Thanet Wind Farm opened on 23 September 2010.[3][4]

History[edit]

In May 2008, Dong Energy began construction of the second wind farm in the Horns Rev area, Horns Rev 2. Construction was completed in September 2009[5] and was inaugurated on September 17, 2009 by Prince Frederik on the Poseidon accommodation platform.[3] For the year of 2012, HR2 reached a capacity factor of 52.0%.[2]

Technical description[edit]

The Horns Rev 2 consists of 91 Siemens Wind Power SWP 2.3-93 wind turbines with a total generating capacity of 209 MW.[4] The foundations are monopiles like on Horns Rev 1.

Accommodation platform[edit]

It has the first offshore wind farm accommodation platform in the world, named Poseidon. It is connected by walkway to the transformator platform,[6] and is 750 square metres (8,100 sq ft) large with 3 decks and weighs 422 tons. On-site accommodation is more efficient than transporting service personnel by boat 2 hours from Esbjerg harbour 60 kilometres (37 mi) away. Flying people by helicopter to turbines like on Horns Rev 1 is not possible on Horns Rev 2 as the turbines there are not built for it, although the transformator platform has a helipad.[7] Poseidon has 24 rooms of 12 square meters each fitted with TV and internet. There is a gym, kitchen, dining room, laundry room, and a study room.
