GE Renewable and Sembcorp to supply converter systems to RWE Renewables

A consortium of GE Renewable Energy’s Grid Solutions and Sembcorp Marine will supply the high voltage direct current transmission (HVDC) system for RWE Renewables’ offshore windfarm Sofia on Dogger Bank, 195 kilometres off the British coast in the North Sea.

Singapore yard Sembcorp Marine has a contract to build an offshore converter platform and other installations. The system will utilise GE Grid's second-generation voltage source convertor valve and feature the first application of its state-of-the-art eLumina™ HVDC Control System. The contract work scope comprises the design, manufacture, installation, commissioning and maintenance of the offshore converter platform (OCP) and the onshore converter station (OCS), including all ancillary equipment.

Sembcorp Marine’s scope of work includes the design, construction, installation and commissioning of the OCP. The OCP comprises a 17,000-tonne topside platform and a jacket foundation structure piled into the seabed 220 kilometres from the nearest shore. Heerema Marine Contractors, based in Leiden, The Netherlands, was commissioned by Sembcorp Marine to transport and install the offshore converter platform.

The platform's fabrication will be executed at Sembcorp Marine’s yard, and offshore installation is scheduled for 2024.
