“Pioneering Spirit”, the world’s largest vessel, has departed Rotterdam on Saturday morning as crowds of people came to watch it begin its voyage towards the southern North Sea.
The Allseas-owned vessel will perform offshore trials throughout the month of August, which will include a series of test platform topsides installation and removal exercises, under varying weather conditions.
“After the successful completion of offshore trials, “Pioneering Spirit” is expected to sail north to the Yme field, offshore Norway, to remove the 13,500 tonne Yme mobile offshore production unit (MOPU) for Repsol,” Allseas reported.

“Pioneering Spirit” 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.
The record-breaking vessel had been moored in Rotterdam’s Alexia haven since January 2015 for installation, commissioning and testing of the topsides lift system.

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, which is scheduled for the summer of 2017.

“Pioneering Spirit” was built in South Korea by Daewoo and arrived in Rotterdam for final outfitting in January 2015.
The installation and commissioning of the topsides lift system beams was completed in August 2016, after which the vessel started offshore tests.
The offshore contractor Allseas had announced earlier this month that “Pioneering Spirit” was ready to leave after completing the test of its “respective lifting capacities of nearly 3,700 metric tonnes”.
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.
