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.
