10,000t topside gantry lift, Dubai
Teams from multiple ALE branches collaborated to design a unique gantry system for the lifting and mating of a 10,000t topside at Drydocks World for the world’s first semisubmersible platformwhich was constructed at the shipyard.
The joining of specialist skills from across the ALE group allows usto design unrivalled systems and solutions to meet our clients needs. Specialist equipment and personnel were mobilised from across the group to build and operate the gantry system. We lifted the topside to a final height of 52.8m.
Once at full height, the semi-submersible hull structure was manoeuvred between the gantry system underneath the suspended topside, a process facilitated by an innovative fendering system designed by Drydocks World. We then lowered the topside to the precisely positioned substructure, releasing weight in a controlled fashion. Welding and lowering operations of the two structures was carried out simultaneously.
