A large subsea module with a weight exceeding 1000T was recently successfully installed. This is the largest heave compensated lift ever done! Two 700T units were connected in parallel, and the module was lifted through the splash zone. At a predefined depth, the Cranemaster units readjusted themselves for maximum landing speed reduction before the module was safely installed on the seafloor at 1400m depth. Cranemaster worked as expected through all phases.
In addition to constructing and supplying the units, Cranemaster was responsible for the full lift calculation. For more info, read this article in European Oil & Gas issue 118, or have a look at a description of the Gorgon project in the October 2014 issue of Oil & Gas Australia.
