The Danish offshore wind farm, Horns Rev 2, has a capacity of 209 MW. The renewable energy produced by the wind farm corresponds to the annual power consumption of 200.000 households in Denmark.

ISC A/S has performed layout and detailed engineering for the offshore substation topside as well as for the four-legged jacket. For the accommodation platform ISC has assisted DONG Energy (now Ørsted) with layout and tender documents.
General description of the project
The platforms are located on a water depth of approximately 13 meters. The substation consists of a closed building housing the electrical equipment whereas the transformer is located on the outside behind an aluminum windscreen. The four-legged jacket has a traditional layout with X-bracings. The jacket extends 28.6 m above the seabed. The piles are driven 30 meters into the seabed and are located within the four legs.
The substation is designed in 3D via the advanced CATIA CAD-system. Besides designing of the platform construction, CATIA is used to determine all sittings, from the high-voltage cables to the concrete foundation, where the submarine cables are lead from the underground to the platform, and where the space left for diverging of the high-voltage cables are very small.
