HVDC DolWin2 is a high voltage direct current (HVDC) link to transmit offshore wind power to the power grid of the German mainland. The project differs from most HVDC systems in that one of the two converter stations is built on a platform in the sea. Voltage-Sourced Converters with DC ratings of 900 MW, ±320 kV are used and the total cable length is 135 km. The project is similar to the HVDC DolWin1 project but has a slightly higher power rating and uses a different design of offshore platform. The platform was designed by Norwegian company Aibel[1] and built by Drydocks World in Dubai[2] and transported to Europe in the summer of 2014[3] to be fitted out at the Aibel yard in Haugesund in Norway.[4][5][6] The platform, which is of a floating, self-installing design not previously used in an HVDC project, sailed out from Haugesund on 1 August 2015[7] and was installed in the North Sea ten days later.[8]

The overall project was built by ABB and was handed over to its owner, TenneT, in 2017.
