PAPENDRECHT, the Netherlands – Iv-Offshore & Energy b.v. (Iv-ONE) has signed the early works contract with Sembcorp Marine Offshore Platforms Pte Ltd. (SMOP) for the engineering of the Sofia high voltage direct current (HVDC) platform.

The Sofia wind farm will be 195 km (121 mi) off the northeast coast of the UK, on the shallow area of the central North Sea known as Dogger Bank.

The company is SMOP’s engineering subcontractor for the balance of plant installation and will provide detailed design for both the topsides and jacket and procurement of topsides equipment.

The Sofia offshore wind farm will consist of 100 turbines, with a total installed capacity of 1.4 GW. The offshore converter platform will convert the electricity generated by the turbines from 66 kilovolts (kV) alternating current up to 320kV direct current before transmission to shore.

Construction of the wind farm is due to begin onshore at its Teesside converter station site early next year, with offshore construction expected to get under way in 2023.

In 2018 UK Grid Solutions Ltd. and Iv-ONE completed a FEED study for the proposed Sofia HVDC platform.
