Extreme precision and sophisticated logistics for Hywind Tampen
Bolt holes
A unique project in many ways, which also involves Dutch input. Breman Machinery is performing specialized machining on the bottom sections of the masts of the wind turbines. 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.
Giant sections
Especially for this purpose, the bottom sections of all 11 turbines were transported from the production site in Bilbao via Rotterdam to Breman Machinery in Genemuiden (NL). With a height of 10 meters, diameter of 8.40 meters and a weight of 180 tons each, this is no small feat!
Extremely precise
Leveling the bottom and drilling these bolt holes is therefore a precision job of the highest order. And it has to be extremely precise: down to +/- two tenths of a millimeter! That is exactly why you need to be at Breman Machinery in Genemuiden.
The experts at Breman Machinery have the right expertise, experience and special machines to level and make bolt holes with extreme precision in giant parts like these bottom sections.
Back ....
Wagenborg Nedlift's 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.
For unloading the giant sections, the lifting specialists deployed, among others, the new Liebherr 700-tonnes capacity crane, the LTM 1650-8.1. Transport was carried out using Scheuerle intercombi modular axle lines.
... and forth
After processing, the bottom sections returned to Bilbao via the same route. This logistical operation was carried out several times in order to process all eleven bottom sections in Genemuiden.
Offshore
Meanwhile, the installation of the offshore floating wind turbines is in full swing and a number of wind turbines are already operational. The complete Hywind Tampen wind farm is expected to be commissioned during 2023.
