16.1 Location Sea laid feeding cable will be laid between the separate turbines and the two transformer stations and between the transformer stations and land. The transformer stations are planned to be located centrally in the wind farm and the distance between them to land will be about 30 km. During the early consultation, a number of different alternative landing points were presented (points were the cable reaches land), see map below. From these landing points, cables will be laid to the CABLE LAYING 165 connection points (the transmission grid). The connection of the wind farm to the grid is planned in two phases. In phase 1 on land, 340 MW is planned to be connected to the grid at Trelleborg North and in phase 2, 300 MW is planned to be connected to the connection point Arrie (Västra Kärrstorp). These two stations are existing transformer stations.
166 CABLE LAYING 16.2 Design The transformer stations will be mounted on a platform standing on four steel legs driven into the seabed. It is likely that monopile or tripod foundations are to be used. For information regarding these foundations, see Chapter 5.4.2. The size of the platforms will be 40 x 40 metres. They are to be placed about 10 metres above sea level and the transformer stations will be about 15 metres high. The total height of the construction above sea level will be about 25 metres. Equipment on the transformer stations will be installed to assure that the safety technique will function in an emergency. The connection between the wind farm and the grid is planned via a three phase AC link. All together, it is likely that four sea cables and four land based cables will be used. The cable is built up in multiple layers separated from each other by bitumen. No liquid substance is used in the cables. The surrounding material is made of a thick, protective covering containing steel wires. The sea cable connecting the wind farm to land will probably have an outer diameter of between 15 and 20 cm and the weight will be about 80 kg/metre. The cable used within the wind farm will be thinner and weigh less than the cable used for the land connection. The cables will be dug, plowed or washed 0.8 – 1.0 metres into the seabed (slightly deeper near the coast). Where the seabed structure does not allow the cable to be washed down due to stones, rocks etc, the cable will instead be securely anchored to the seabed. At the landing points a shaft will be dug for each cable or alternatively a larger shaft for all cables. Also on land the cables will be dug down to a depth of about one metre. The laying of the cables will need a working area of around 8–12 metres. Within this area, shafts will be dug, cables laid in position and joined. The cables will be transported to the working area on cable drums each containing 60-100 metres, depending on diameter. Transformer station, Nysted wind farm
