Allseas’ single-lift installation / decommissioning and pipelay vessel “Pioneering Spirit” has executed its maiden heavy lift project, removal of the 13,500 tonne Yme mobile offshore production unit (MOPU) in the North Sea, 100 km off the coast of Norway, on August 22, 2016 for Repsol Norge.
The Yme MOPU is a jack-up type platform standing on three steel legs of 3.5 m diameter, which are inserted approximately 10 meters inside the subsea storage tank columns at 93 meters water depth.
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.
Following delivery of the platform, the vessel is scheduled to return return to Rotterdam where the remaining four topsides lifting beams will be installed for the Shell Brent Delta topsides removal, scheduled for the summer of 2017.
