Dogger Bank Wind Farm has unveiled an unmanned High Voltage Direct Current (HVDC) offshore substation. Removing the need for personnel to stay on the platform meant it was then possible to eliminate elements such as the living quarters, helideck and sewage systems, resulting in a 70% reduction in weight (per megawatt) of the topside compared to previous platforms installed, and cost savings of hundreds of millions of pounds (GBP).A joint venture between SSE Renewables, Equinor and Eni, SSE Renewables is leading on the construction and delivery of Dogger Bank Wind Farm. Equinor will operate Dogger Bank Wind Farm on completion for its lifetime of up to 35 years. Dogger Bank will be the first offshore wind project in the UK to use HVDC technology to transmit the electricity produced back to shore
