End date

Client: TenneT

Location: 130 km off the coast of Germany (construction took place in the UAE)

Scope: Engineering, procurement, construction and offshore installation of the BorWin3 platform

 

Petrofac, in consortium with Siemens was awarded a contract by TenneT, the German-Dutch transmission grid operator, for the BorWin3 offshore wind farm grid connection.  Petrofac is responsible for the construction and offshore installation of the BorWin Gamma platform, which will house a Siemens high voltage direct current (HVDC) station that converts the alternating current produced by the wind turbines to direct current before transmitting it onshore to the German national grid. 

It’s one of the largest offshore project platforms constructed in the UAE – and it’s also a giant demonstration of Petrofac’s diversification from oil and gas into renewable energy.

The platform's jacket has been successfully installed in the North Sea, nearly 130 kilometres off the German coast, and the fabrication and construction of the topside has been completed. The platform now awaits the arrival of the topside for connection.

The final stages of the project in Drydocks World saw the mega jacking and load-out of the topside, completing one of the heaviest and biggest jacking lifts in the Middle East.

When operational, the platform will house a Siemens 900 megawatt HVDC station that will convert the alternating current produced by the wind turbines to direct current before transmitting it onshore to the German national grid, from where it will supply more than one million German households with clean electricity from wind power. It will be one of the world’s heaviest and largest HVDC platforms, with the topside six storeys high, weighing in at 20,000 tonnes and about the size of half a football pitch.

BorWin3 construction facts

  • Construction of the BorWin3 platform took place in Drydocks World, Dubai, which extends across an impressive 10 square kms
  • The topside took over 13.5 million man-hours to construct and used 10,500 tonnes of steel – more than the Eiffel Tower
  • Nearly five square kms – half of the Drydocks area – was taken up by the project
  • Such is the scale of the site that many of the staff used bicycles to get around
  • At peak, more than 1,500 workers were engaged in the construction of the platform
