Dubai shipyard Drydocks World has shipped out the 900MW BorWin Gamma platform which will be installed in the German North Sea.

The 18,000-tonne topside has set sail on heavy lift vessel Xiang He Kou and will be installed some 130km off the German coast in water depths of about 40 metres, transmission system operator TenneT said.

BorWin Gamma will be the grid hub of the BorWin3 HVDC connection scheduled to go online in 2019.

In 2014, TenneT ordered BorWin Gamma from a consortium of Petrofac and Siemens.

Siemens supplied the complete HVDC converter technology and main electrical equipment, while Petrofac's remit covered engineering, construction and offshore installation of the platform.

Petrofac awarded the contract to Drydocks World for fabrication, commissioning and load-out of the topside.
