Seatrium and GE Vernova Consortium awarded third contract

Seatrium Limited and GE Vernova Inc. announced that they have been awarded a third contract by TenneT TSO B.V. for the construction of a 2GW High Voltage Direct Current (HVDC) electric offshore transmission system in the Netherlands. The project is slated to begin this month, with commissioning expected by 2031.

This contract is part of the five-year Framework Cooperation Agreement with TenneT announced by the Seatrium-GE Vernova consortium in March 2023. The agreement was signed to cover three projects, each valued at approximately €2 billion: IJmuiden Ver Beta, IJmuiden Ver Gamma, and Nederwiek 2. The current contract is for Nederwiek 2, TenneT’s third project with this consortium. The contracts for IJmuiden Ver Beta and IJmuiden Ver Gamma were awarded to the consortium in March 2023.

The system

The HVDC system will support TenneT’s sustainability goal of connecting 40GW of offshore wind energy in the German and Dutch North Sea and will serve the Nederwiek 2 offshore wind farm, located approximately 95km off the coast of the Netherlands.

“With the successful call-off of Nederwiek 2 from the Framework Cooperation Agreement with our Partners GE Vernova and Seatrium, we are now starting into the delivery of the third project with this consortium,” Dr Johannes Kammer, Associate Director of Large Projects Offshore – 2GW, TenneT, said. “We are pleased with the progress we made already in the first two projects with these partners. Now we experience the benefits of using the works from the initial two projects on the next one as we design one and build it many times.”

Seatrium’s scope of work will include the engineering, procurement, construction, transportation, installation and commissioning of the 2GW HVDC Offshore Converter Platform. GE Vernova’s Grid Solutions will be responsible for the engineering, procurement, construction, installation, and commissioning (EPCI) of the HVDC converter stations.

Executive comments

“We are pleased to partner with TenneT and GE Vernova to deliver this transformative offshore wind solution,” Mr Samuel Wong, Executive Vice President, Fixed Platforms at Seatrium, said. “This project underscores our commitment to helping our customers achieve their renewable energy goals by providing innovative and cost-effective solutions that help accelerate the energy transition.
