Seatrium and Aibel Seek Arbitration to Resolve DolWin 5 Disputes

Seatrium, through its wholly owned subsidiary Seatrium New Energy (SNE), and consortium partner Aibel have started arbitration proceedings for the disputes related to the delivery of TenneT’s DolWin 5 offshore converter platform project in Germany’s North Sea.

The arbitration arises from disputes under a consortium agreement signed in May 2019 covering the design, engineering, procurement, construction, installation and commissioning of the 900 MW offshore converter platform for the end-customer TenneT.

The project secured pre-merger and sits outside TenneT’s 2GW program. It is not related to the four HVDC units currently in Seatrium’s order book.

In the DolWin5 project, TenneT is installing an offshore grid connection system in the North Sea with a capacity of 900 MW using extra-high voltage direct current (HVDC) transmission technology. The three-phase alternating current generated by the wind farms at sea is converted into direct current on the offshore platform DolWin epsilon.

The platform is based on Aibel’s design for the DolWin cluster in the German sector of the North Sea.

Despite the start of arbitration, the parties continue to work on the project, which is currently located in the German North Sea and remains targeted for delivery in 2026.

Following discussions, SNE and Aibel agreed to
