Offshore description
Inch Cape’s offshore site is located in the North Sea, 15 kilometres off the Angus coast and covering a total of 150 square kilometres, roughly the size of the island of Hoy in Orkney. It will comprise up to 72 wind turbine generators, each standing up to 274 metres tall. The turbines will be installed on a combination of monopile and jacket foundations in water depths ranging from 34 metres to 64 metres. The monopiles will be amongst the world’s largest with lengths of up to 110 metres, a maximum diameter of 11.5 metres and with the heaviest weighing 2700 tonnes.
There will be one 66 kilovolt (kV)/220kV substation on a jacket foundation at the heart of the wind farm. Electricity from the offshore substation will be transmitted 85 kilometres via two 220kV subsea export cables to landfall in Cockenzie, East Lothian.
The project is set to be operated and maintained out of a purpose-built facility at the Port of Montrose, in Angus.
Construction progress
Work is underway on the construction of the topside and jacket foundation that will comprise the Inch Cape offshore substation. The key fabrication activity is taking place at the Smulders yard in Wallsend, near Newcastle in the UK.
