The project presented several technical challenges, which required innovative solutions. The crane’s centre of gravity was located relatively high up and its base protruded by 4 m off the hull of Jumbo’s vessel Fairplayer, which was to ship it.
Jumbo and Eurocrane engineers developed a one-off solution which included adding ballast boxes which added ballast weight on a low elevation, decreased the supported width of the crane structure which was partly overhanging and acted as load spreaders and outriggers for the lifting points.
The crane was assembled in Aveiro (Portugal) and placed on board the Fairplayer in a single lift using its two 900-tonne mast cranes. The relatively high location of the centre of gravity meant the lift was a critical one: strong winds could cause the crane to incline.
