DNV GL has been awarded a contract by Cosco Shipping Company Limited for the installation engineering services for the BorWin gamma high voltage direct current (HVDC) converter platform. TenneT is developing the offshore AC/DC converter platform BorWin gamma as part of the grid connection project BorWin3. 

A consortium of Siemens and Petrofac has been contracted by TenneT to design, build and install BorWin gamma.  Cosco Shipping was awarded the transportation and installation contract by Petrofac and has chosen DNV GL's Noble Denton marine services as partner to fulfill the dynamic positioning (DP) float-over job. The installation is expected to commence in the summer of 2018.  Once completed, it will transmit approximately 900 MW of wind power. Scheduled to go online in 2019, the BorWin gamma platform will be installed nearly 130 kilometres off the German coast in the North Sea, at a water depth of approximately 40 metres.  The 900 MW DC transmission will be through 320 kV cable of 160 kilometres length.
