Under the contract, DNV GL’s Noble Denton marine services will undertake the dynamic positioning (DP) float-over work which involves heavy module installation method using a DP vessel.

The HVDC converter platform, BorWin gamma, will provide an essential renewable offshore resource to address the increasing energy demands.

The platform is being developed by Dutch-German transmission system operator TenneT as part of the grid connection project BorWin3.

As part of this effort, TenneT selected a consortium of Siemens and Petrofac to design, build and install BorWin gamma.

COSCO SHIPPING was later awarded a subcontract by Petrofac to provide transportation and installation services and has selected Noble Denton as partner to fulfill the dynamic positioning (DP) float-over job.

DNV GL-Oil & Gas Greater China project director Andy Wang said: "DNV GL has jointly completed 10 installations successfully around the world with COSCO.

"Our experts have a solid track record in DP float-over that won the confidence of Petrofac and Siemens."

The 18,000 metric tons BorWin gamma, which will be one of the heaviest HVDC platforms installed till date, represents the first DP float-over operation in the North Sea and Europe.

Upon completion of installation in the summer of 2018, the platform will enable 900MW of wind power transmission to meet the annual electricity needs of 1 million German households.
