Allseas announced today that the Pioneering Spirit dynamically positioned vessel has completed its maiden heavy lift project.

The single lift installation/decommissioning and pipelay vessel successfully executed the removal of the 13,500 tonne Yme mobile offshore production unit (MOPU) in the Norwegian North Sea, Allseas reported.

“With this platform removal, Allseas was able to demonstrate the unique single-lift capabilities of Pioneering Spirit”, the company said in a statement.

 The removal occurred on 22 August and was contracted by Repsol Norge AS.

The Yme mobile offshore production unit was located in the North Sea, 100 kilometres (62.13 miles) off the coast of Norway.

The Yme MOPU is a jack-up type platform standing on three steel legs of 3.5 metres of diameter (11.48 feet).

The legs are inserted approximately 10 metres inside the subsea storage tank columns at 93 metre water depth.

The removal of such a heavy facility in a single lift marks a new era in the decommissioning of offshore oil platforms.

Before, these would have to be taken apart piece by piece, which was much more time-consuming.

After this, Pioneering Spirit will remove four topsides at Shell’s Brent field offshore the UK, to commence in 2017, according to media sources.

“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,” Allseas informed.

Pioneering Spirit is a dynamically positioned vessel for single-lift installation and removal of large offshore oil and gas platforms and the installation of oil and gas pipelines.

The vessel was built in South Korea by Daewoo and arrived in Rotterdam for final outfitting in January 2015.

The installation, commissioning and offshore testing of the topsides lift system beams was completed in August 2016.
