DNV GL has been contracted to provide technical advisory support on feasibility studies for a high-voltage direct current (HVDC) offshore wind substation in China. China is exploring locations that are further offshore. To this end, Huadong Engineering Corporation is planning a 1.1GW offshore windfarm some 90 km off the coast of Jiangsu Province in eastern China.
To support the realisation of this pioneering project, Huadong has contracted DNV GL to supply technical trainings, advices and support on their feasibility study on aspects of conceptual design and risk assessment for an offshore HVDC transmission system to export offshore power from the windfarm to the mainland. The system will include an offshore HVDC converter station, submarine cables and onshore HVDC converter station. This will be the first offshore Voltage-Source Converter HVDC system in China.
