Danish companies ISC Consulting Engineers and Semco Maritime have completed the detailed design of two topsides that will feature at Orsted’s 1400MW Hornsea 2 offshore wind farm off the east coast of England.
The project will deploy a single 7500-tonne HVAC topside and a 1200-tonne reactive compensation unit to help bring power to shore, ISC said.

The larger unit will be supported by a six-legged jacket foundation, while the smaller platform will be mounted on a four-legged structure.
Both topsides will be fabricated by Sembcorp Marine at facilities in Singapore and are due to be delivered to Orsted in early 2021.
Hornsea 2 will feature 165 Siemens Gamesa 8MW turbines with rotor diameters of 167 metres.
The project is due online in 2022.
