Allseas’ has successfully completed commissioning of the Topsides lift system and the major part of the harbour test programme of the single-lift installation/decommissioning and pipelay vessel Pioneering Spirit in the Alexia harbour, Rotterdam, at the end of July 2016.
All twelve installed topsides lifting beams on board Pioneering Spirit have been tested to their respective lift capacities of nearly 3700 metric tons. The last of the four tests, involving four beams lifting 14,700 tonnes, was performed on 23 July. During harbour lifting trials the twelve beams together lifted over 44,000 tonnes.
Pioneering Spirit is expected to perform offshore trials and the test platform topsides installation and removal exercises in the Southern North Sea throughout August. Removal of the 13,500 tonne Yme mobile offshore production unit (MOPU) offshore Norway for Repsol is planned to occur following successful completion of this test programme, and once all other necessary prerequisites and approvals are in place.
Following removal of the Yme platform, Pioneering Spirit will 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.
