VOS Stone Keeping Busy at Hohe See

Vroon’s walk-to-work (W2W) vessel VOS Stone is currently operating in the Hohe See wind farm in the German North Sea.


Supporting Siemens Gamesa, VOS Stone is on duty 24/7, deploying service teams to the wind turbines, Vroon said. These operations are carried out via a gangway or by a crew transfer vessel.

In addition to these duties, VOS Stone is also supplying fuel, water, and food to the jack-ups in the wind farm, with all operations performed from the Danish port of Esjberg.

Located approximately 98 kilometres from the German coast, the 497MW Hohe See wind farm covers an area of roughly 42 square kilometres, with water depths of up to 40 metres.

The wind farm comprises 71 Siemens Gamesa 7MW wind turbines the last of which was installed at the site mid-August by Fred. Olsen Windcarrier’s jack-up Blue Tern. The wind farm delivered first power mid-July.

The commissioning of all of the 71 turbines at Hohe See, as well as the 16 units at the neighboring Albatros, is expected to take place by the end of the year.
