Huisman to build world’s largest cranes for new semisubmersible lift vessel
Huisman has received a letter of intent for the delivery of the world’s largest cranes to Heerema’s planned new semisubmersible crane vessel.
While Huisman is known for its mast crane design, these cranes will be tub-mounted. The two cranes will be built by the Huisman production facility in China. The final decision to build this new semisubmersible crane vessel will be made by Heerema before the end of this year.
The cranes will have a lifting capacity of 10,000 metric tons (11,023 tons) at a radius of 48 m (158 ft). They will also feature a 2,500-metric ton (2,756-ton) aux hoist and a whip hoist with a maximum reach of 155 m (509 ft). The main hoist, in a reduced reeving, can lift 1,000 metric tons (1,102 tons) to 1,000 m (3,281 ft) of water depth, and is fitted with active heave compensation.
