Dutch company Mammoet has staked a claim for two world records – the heaviest lift on dry land and the heaviest load-out.
The heaviest lift claim has been made for the salvage of the gantry crane which collapsed in Denmark’s Odense Steel shipyard in December. The 1,550t lift by the MSG-50 was featured in last month’s Cranes Today. The claim that it was a record has only subsequently been made.
The Odense lift beats the 1,359t lifted at a refinery in Texas by arch-rival Van Seumeren with its CC 12600 (the crane on the cover of the April issue of Cranes Today). However, it could be argued that the two lifts should not be compared because the MSG-50 uses strand-jacks rather than
a winch.
The heaviest load-out record was set at Amec Process & Energy’s Wallsend yard on the river Tyne in northeast England where Mammoet moved an 11,727t integrated offshore deck on 426 axle lines of Scheuerle self-propelled modular transporters (SPMTs).
The combined process, utilities and quarters integrated deck is the heaviest oil and gas structure ever moved on wheels, Mammoet claimed. The structure, 70m long and 63m high, was built by Amec for Shell Expro’s Shearwater gas/condensate development.
Mammoet wheeled the load from the construction yard, over ramps, and onto a sea barge. It will subsequently be towed out to the North Sea, 200km off Aberdeen.
A total of 1,704 SPMT wheels were installed underneath the offshore structure. Initially, a site move was carried out, which involved moving the platform and rotating it 90° to line it up with the load-out ramp and barge.
