Wind Energy – Floating Wind
Breman Machinery from Genemuiden (NL) has performed specialized machining on the bottom sections of the masts of the floating wind turbines in the Hywind Tampen Floating Offshore Wind Farm, 140 kilometers off the Norwegian coast.
These so-called bottom sections will be leveled and provided with bolt holes. This is necessary to attach the bottom sections to the floating foundation.
Especially for this purpose, the bottom sections of all 11 turbines, with a height of 10 meters, diameter of 8.40 meters and a weight of 180 tons each, were transported from the production site in Bilbao via Rotterdam to Breman Machinery in Genemuiden.
Leveling the bottom and drilling these bolt holes is a precision job of the highest order. It has to be extremely precise: down to +/- two tenths of a millimeter! Breman Machinery has the right expertise and special machines to do so.
A Wagenborg Nedlift team came in to execute the transport and lifting activities on site in Genemuiden. This involved unloading the bottom sections from the barge using mobile cranes and transporting them to the construction hall.
After processing, the bottom sections returned to Bilbao via the same route.
Meanwhile, the installation of the offshore floating wind turbines is in full swing and a number of wind turbines are already operational. The Hywind Tampen Floating Offshore Wind Farm will be the world’s largest floating wind farm and will power the five offshore oil platforms at Snorre and Gullfaks.
