The HVDC Light link, which will enable power from shore to supply the offshore complex, will allow BP to substitute the use of offshore gas turbines to generate electricity.
ABB has installed a converter station onshore which is connected by an HVDC submarine cable to a second converter on the platform, about 294km offshore.
This project will allow 78MW of power to be supplied from the mainland to run the field facilities, including a new production and living quarter platform.
BP is commissioning the new platform to replace some of the existing platforms at the Valhall oil and gas field during next year.
