Seatrium has announced the sailaway of the DolWin epsilon, a High Voltage Direct Current (HVDC) Offshore Platform for European grid operator, TenneT. The platform, part of the DolWin5 project, is a collaboration between Seatrium and Aibel.
The platform will be used for collecting, converting, and transmitting high-voltage power generated by offshore wind turbines in the German sector of the North Sea. Upon completion, the DolWin epsilon will be transported to Norway's Haugesund for high-voltage electrical equipment installation and commissioning, carried out together with Hitachi Energy as Consortium's subcontractor and supplier for the HVDC technology, before being transported to Germany for offshore installation. Based on a Gravity Based Structure (GBS) design, the DolWin epsilon features living quarters, a helideck and lifting cranes. It is designed with a lifespan of 30 years and can convert approximately 900MW of electricity.
