On July 1st, DEME installed the first monopile for the Nordlicht I offshore wind farm in the German North Sea.

This marks the start of a key offshore construction phase for Germany’s largest offshore wind project, strengthening Vattenfall’s offshore portfolio and supporting the large-scale expansion of other fossil-free energy in Europe.

“With the installation of the first monopile, Nordlicht is visibly taking shape in the waters of the North Sea. It’s an important step forward for Vattenfall and at the same time a meaningful contribution to the energy transition, strengthening energy security and competitiveness in Europe. Projects of this scale require precise planning, strong partnership across the supply chain, and a clear focus on safety and execution. Seeing the project take shape offshore is a proud moment for the entire team.” says Cyril Moss, Project Director Nordlicht at Vattenfall.

The installation was carried out by DEME, which is responsible for the transport and installation of the foundations and transition pieces for Nordlicht I and II.

Nordlicht I will comprise 68 monopile and transition piece foundations. Each monopile is up to 80.5 metres long, making it almost as long as a football pitch, and weighs up to 1,290 tonnes.
