Iv-Offshore & Energy b.v. 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 (10,000 T). Iv-Offshore & Energy is SMOP’s engineering subcontractor for the balance of plant installation in this endeavor and shall provide detailed design for both the topside and the jacket, and the procurement of topside equipment.

The offshore converter platform will convert the electricity generated by the turbines from 66 kV alternating current (AC) up to 320 kV direct current (DC) before transmission to shore. In 2018 UK Grid Solutions Ltd (GE) and Iv-Offshore & Energy completed a FEED study for the proposed
Sofia HVDC platform.

The 1.4 GW
Sofia offshore wind farm is located 195 kilometres from the UK coast on Dogger Bank, in the shallow area of the central North Sea. Construction of the wind farm is due to begin onshore at its Teesside converter station site in early 2021, with offshore construction expected to get underway in 2023.

The project will see the installation of 100 of Siemens Gamesa's SG 14-222 DD 14 MW platform featuring 108-metre carbon and fibreglass blades and a 222-metre diameter rotor, sweeping an area of 39,000 m2.
Sofia is set to be the first European project to include the model, which will be market-ready by 2024.

The 100 turbines together could generate enough green electricity to supply almost 1.2 million average UK homes with their annual electricity needs. At around 5.4 Twh per annum that’s almost half of all the electricity used in the UK’s North East each year.
