Iv-Offshore to design Sofia offshore wind farm substation

England: Singapore’s Sembcorp Marine Offshore Platforms has awarded the early works contract to Iv-Offshore & Energy for the engineering of the offshore wind farm Sofia HVDC platform.

The wind farm site is located 195 km off the coast of the North East of England and on the shallow central area of the North Sea known as Dogger Bank.

Earlier this month, RWE has selected a GE Renewables / Sembcorp Marine JV as the supplier for HVDC electrical transmission system.

Sembcorp Marine has now selected the Dutch engineering firm Iv-Offshore & Energy as its engineering subcontractor. Iv Offshore will provide detailed design for both the topside and jacket and procurement of topside equipment.

Sofia Offshore Wind Farm will consist of 100 wind turbines, with a total installed capacity of 1,400 MW. The offshore converter platform will convert the electricity generated by the turbines from 66 kV AC up to 320 kV DC before transmission to shore.

“For Iv-Offshore & Energy the contract is a great leap forward in the world of offshore HVDC engineering. We have planted our flag in this sector through our involvement starting with Borwin Alpha (400 MW) followed by Dolwin Alpha (800 MW) and Helwin Béta (690 MW) platforms and various engineering and design studies such as the 2 GW offshore grid connection FEED for TenneT. We are honored to add the Sofia platform to our HVDC experience list,” the company said in a statement.
