After visiting a main bearing exchange in the USA, after several meetings with our client, after creating conceptual designs, basic designs, and detailed designs, a design package was finally completed by Eager.one. From this set of drawings, calculations, memos and manuals, a special crane has been constructed: the RotorHook™. A five-crane system: RotorHook™, GenHook™,...
Sheerlegs 1200t Crane design
Our client assigned Eager.one to design major modifications to one of their sheerlegs.
Sheerlegs 1200t Crane design
This sheerlegs was suggested to install tripods (offshore wind turbine foundations) on the seabed. The original boom had the lifting capacity, but could not meet the requirements with respect to lifting height.
A longer boom has been designed along with an extension of the A-frame (back mast) to cope with the decreasing angles of the luffing tackles.
A challenge was to deal with the fatigue of the various components of the sheerlegs, some parts have been designed new, but others should be reused and these already had a fatigue history.
After completing the design with calculations and workshop drawings a design appraisal has been supplied by DNVGL.
