Serial production of monopiles up to 11 meters

Market developments indicate that in the future even more powerful wind turbines (10-12 MW) will be located in deeper water. In anticipation of these developments, Sif Group has further expanded its production capacity. The first monopiles were assembled at the end of 2016, and the first load-out took place at the deep-sea quay in January 2017. With the addition of this extra capacity, Sif is able to produce and coat monopiles with a diameter of an impressive 11 meters and a maximum weight of 2000 tonnes, using lean manufacturing serial production technologie .
