Dogger Bank reveals world-first in HVDC offshore platforms

Step change in design

'We've committed to build this project with record low CfD strike prices and the associated benefits this provides to UK electricity consumers. We will do this by using the latest technologies to ensure we build and operate the wind farm efficiently, while achieving the highest standards in safety. In order to build this complex infrastructure project competitively, whilst introducing a new technical solution here in the UK, the Dogger Bank project team needed to drive a huge step change in design,' said Steve Wilson, Project Director of Dogger Bank Wind Farm.

Working closely with platform manufacturer Aibel, the Dogger Bank team were challenged to design the first unmanned offshore HVDC substation in the world.

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).
