Pioneering Spirit Ready to Remove North Sea Platforms

Offshore contractor Allseas is ready to start the removal of a test platform in the North Sea using its decommissioning vessel Pioneering Spirit.

The giant vessel is then expected to move on to remove the Yme mobile offshore production unit (MOPU), offshore Norway.

“All twelve installed topsides lifting beams on board “Pioneering Spirit” have been tested to their respective lift capacities of nearly 3,700 metric tonnes,” the company informed.

Allseas said it has successfully completed the commissioning of the topsides lift system and most of the harbour test programme for the vessel.

The programme was implemented at the Alexia harbour in Rotterdam, Netherlands, and was completed at the end of July.

The last of the four tests was performed on 23 July and involved four beams lifting 14,700 tonnes.

During the lifting trials in the harbour, the twelve beams together lifted more than 44,000 tonnes, the company stated.

Pioneering Spirit, formerly known as Pieter Schelte, is a dynamically positioned vessel for single-lift installation and removal of large offshore oil and gas platforms, as well as the installation of oil and gas pipelines.

Throughout the month of August, Pioneering Spirit is expected to perform offshore trials and test platform topsides installation and removal exercises in the Southern North Sea.

After the test programme is successfully completed and after all other necessary requirements and approvals have been implemented, the vessel is expected to work on a project for Repsol, which involves the removal of the 13,500 tonne Yme MOPU.

After the removal of the Yme platform, Pioneering Spirit is expected to return to Rotterdam, where the remaining four topsides lifting beams will be installed for the Shell Brent Delta topsides removal, scheduled to occur in the summer of 2017.
