So far 80 monopile foundations and 71 transition pieces have been installed at Meerwind said Jens Assheuer, managing director of WindMW, which is building the 288MW project and will operate it.

The company will start installing the 80 Siemens 3.6MW turbines next week with help of Seajacks’ Zaratan installation vessel, Assheuer said.

Later the Leviathan vessel will also start adding turbines at the wind farm, 23km north of the German island of Helgoland.
