ZTT Completes Gode Wind 3 Submarine Cable Work Offshore Germany

Grid Connection

May 7, 2024, by Adnan Memija

ZTT Submarine Cable & System has finished the installation and termination of the 155 kV submarine cable connecting the Gode Wind 3 offshore wind farm to the DolWin kappa offshore converter platform in Germany.

In 2020, TenneT contracted ZTT Submarine Cable & System to link the 253 MW offshore wind farm to the DolWin kappa converter platform in the North Sea.

The cable system was produced at ZTT’s manufacturing base in Nantong, China, and then transported to Europe. The cable-laying operations were carried out by the subcontractor Asso.subsea from Greece.

The 16-kilometre-long submarine cable is protected by Tekmar’s cable protection system (CPS).

In addition to the installation of the submarine cable, ZTT also signed the Project Acceptance Certificate (PAC) with TenneT for the Gode Wind 3 EPCI project.

DolWin kappa offshore platform, which is the centerpiece of the 900 MW DolWin6, was installed at its offshore construction site in September 2022. A year later, DolWin6, TenneT’s 13th offshore grid connection, was commissioned.

When it comes to Gode Wind 3, the offshore wind farm is currently under construction alongside the Borkum Riffgrund 3 offshore wind project.

All of the 24 monopiles were installed at the wind farm site in February this year. The wind turbine installation is also about to commence with Seaway7’s newbuild Seaway Ventus carrying out the work.
