BorWin3 project refers to a 900MW DC grid connection system in the North Sea cluster 8 developed by TenneT. The system’s direct current is transmitted from BorWin gamma offshore converter platform to a TenneT substation located in Emden/Ost, through a 160km connection. The aforementioned length corresponds to both the onshore (30km) and the offshore (130km) cables. The submarine cables (2x HVDC and 1x FO) are bundled. The project’s site and cable route are presented in the following figure.

Prysmian Group has awarded Assodivers Group the final pull-in operations on BorWin Gamma offshore platform of each cable separately, i.e. two (2) pull-in operations for the HVDC cables and one (1) pull-in operation for the FOC.
