Dogger Bank Wind Farm has unveiled a “revolutionary platform design” that will deliver a 70% reduction in the weight of its topsides.
The High Voltage Direct Current (HVDC) offshore substation, which the developers have hailed as the “world’s first”, will become the largest of its kind at 1.2 gigawatts (GW) when its installed as part of the first phase of the project in 2023.
The development will be the first offshore wind project in the UK to use HVDC to transmit the electricity produced back to shore.
The technology allows the power generated to be transmitted efficiently over long distances while minimising losses.
Working closely with platform manufacturer Aibel, the Dogger Bank team were challenged to design the first unmanned offshore HVDC substation in the world.
By removing the need for workers to stay on the structure, developers were able to axe the living quarters, helideck and sewage systems, resulting in a 70% reduction in weight per megawatt of the topside compared to previous installations.
