All wind turbines have been installed at the 140 MW Akita Noshiro wind farm offshore Akita Prefecture, Japan.

Wind farm installation vessel Seajacks Zaratan was in charge of transporting and installing the turbines at the site.

The jack-up installed the first Vestas V117-4.2 MW wind turbine in early July.
