AALST, Belgium Jan De Nul Group’s jackup vessel Vole au vent has installed 36 of the 72 turbines for Vattenfall’s Kriegers Flak offshore wind farm in the Danish sector of the Baltic Sea.

The first Siemens Gamesa 8.0-167 DD wind turbine was installed on Jan. 27, 2021. The last turbine is scheduled to be installed in mid-June.

For the first time since its expansion in 2018, the port of Roenne on the Danish island of Bornholm is serving as marshalling harbor for the construction of an offshore wind farm.

Bert Reynvoet, Project Manager for the Kriegers Flak offshore wind farm, said: “When a large installation vessel like the Vole au vent enters a port for the first time, it is always a bit exciting. Moreover, it was new for everyone involved, but thanks to the top service of the port and our local partners, Roenne turns out to be a perfect marshalling harbor. An absolute boost in these challenging times.”

In 2017 and 2018, Jan De Nul Group designed, built, and installed two gravity-based foundations for the wind farm’s high-voltage substations. Its crane vessel Rambiz installed the 8,000- and 10,000-metric ton concrete structures.

Located 15-40 km (9.3-25 mi) off the Danish east coast, the 600-MW Kriegers Flak offshore wind farm is expected to be fully operational by the end of the year. It is expected to provide the annual electricity needs of about 600,000 Danish households.
