The Hornsea Project Two Offshore Windfarm will be built 89 km off the Yorkshire coast and will become the world’s largest wind farm when it is expected to be operational in 2022. Amongst other the substation will also set a record for AC substations with a capacity of 1320 MW and a topside weight of 7,500 ton supported by a 6 leg jacket.

The Hornsea 2 project was undertaken by ISC and executed in 2018 alongside detailed designs of offshore substations also performed for offshore wind farms Moray Firth and Triton Knoll in the UK and for the Northwester wind farm in Belgium. With detailed designs carried out by ISC in 2018, ISC has now executed the detailed design for 32 offshore wind farm substations that are either installed offshore or in fabrication.
