Pioneering Spirit removing the Yme platform in 2016

Allseas’ dynamically positioned single-lift installation/decommissioning and pipelay vessel “Pioneering Spirit” successfully executed her maiden heavy lift project, removal of the 13,500 t Yme mobile offshore production unit (MOPU) in the North Sea, 100 km 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 3.5 m diameter, which are inserted approximately 10 m inside the subsea storage tank columns at 93 m water depth. With this platform removal, Allseas was able to demonstrate the unique single-lift capabilities of “Pioneering Spirit”. The platform was sea-fastened on board and the vessel is currently on her way to the newly developed dismantling yard in Lutelandet, Norway. Pioneering Spirit (formerly Pieter Schelte) is the largest construction vessel in the world. Inspired by the offshore heavy lifting pioneer Pieter Schelte Heerema (1908–81) and designed completely in-house, the vessel is designed for the single-lift installation and removal of large oil and gas platforms and the installation of record-weight pipelines. The emergence of Pioneering Spirit signifies a step-change in offshore installation and decommissioning. Capable of lifting entire platform topsides of up to 48,000 t and jackets up to 20,000 t in a single piece, she significantly reduces the amount of offshore work associated with installation and decommissioning, moving the work onshore where it is safer and more cost effective.
