Jan De Nul Group’s heavy lift vessel Les Alizés has installed the first of 83 monopile foundations at Ørsted’s Borkum Riffgrund 3 offshore wind farm off the German coast.
The foundations of the wind farm measure up to 100 m long and weigh up to 1,500 tonnes. They are manufactured by Steelwind in Nordenham and at Bladt Industries’ Lindø plant in Denmark.
Borkum Riffgrund 3 will be the largest wind farm in German waters to date. Next year, SG 11.0-200 DD offshore wind turbines will be installed on the foundations.
This installation campaign started immediately after the last monopile foundation for the Gode Wind 3 project (253 MW) was installed. In total, Les Alizés put 24 monopiles in place for the future turbines, including one monopile and topside of the offshore substation.
