Cable Connection Needed for German Offshore Platform – Offshore WIND

Transmission system operator TenneT has issued a notice for a turnkey contract covering the cable system needed to connect the BorWin6 offshore platform to the German grid.

With the 930 MW BorWin6 project, TenneT is planning a direct current connection in the North Sea Cluster 7.

Scheduled to be commissioned by 2027, the BorWin6 offshore grid connection will collect the three-phase current generated at an offshore wind farm to be selected in the 2022 auction round.

The three-phase current will then be converted into the direct current on the BorWin kappa offshore converter platform and transported to the mainland in Bsum via an export cable approximately 189 kilometres in length.

From there, the electricity is to be transported to the BUTL grid connection point near Bttel via an approximately 46-kilometre underground cable.

The content of this tender is the turnkey and ready-to-use construction of the entire DC cable system required for this, TenneT said.

The cable system consists of two DC single conductor submarine cables, two DC single conductor land cables, optical fibers, sleeves, and cable terminations.

In addition, the scope of delivery and performance of the cable system includes its design, manufacture, delivery, construction, installation and commissioning as well as all systems, ancillary systems and components that are required for safe and highly available operation of the cable system.

The tender remains open until 14 July. The contract will have a duration of 64 months.
