Pioneering Spirit Completes Maiden Heavy Lift Project
Allseas’ dynamically positioned single-lift installation/decommissioning and pipelay vessel Pioneering Spirit successfully executed her maiden heavy lift project, removal of the 13,500t Yme mobile offshore production unit (MOPU) in the North Sea, 100km off the coast of Norway, on 22 August 2016 for Repsol Norge AS.
The Yme MOPU is a jack-up type platform standing on three steel legs of 3.5m diameter, which are inserted approximately 10m inside the subsea storage tank columns at 93m water depth. With this platform removal, Allseas was able to demonstrate the single-lift capabilities of Pioneering Spirit.
The platform has since been sea-fastened on board and the vessel is currently on her way to the newly developed dismantling yard in Lutelandet, Norway.
