The giant ‘Pieter Schelte’ is now on its way to Rotterdam, sailing from South Korea, where it was recently delivered. The 382 m long and 124 m wide multi-purpose vessel, owned by Allseas, will be used for both lifting and installation of oil platforms and jackets. The vessel is also able to lay pipelines. The massive heavy lifter will be able to lift topsides weighing up to a maximum of 48,000 tonnes. Positioned at the bow of the vessel is a slot, 122 m long and 59 m wide, where topsides are lifted using eight sets of horizontal lifting beams.
Construction of the vessel started at Daewoo’s Okpo yard in 2011. The completed vessel which departed Okpo on November 17, 2014 is expected to arrive in Rotterdam at the end of the year sailing under its own power. The maximum speed of the vessel is 14 knots. Edward Heerema, the president of Allseas, named the vessel in honor to his father Pieter Schelte Heerema.
In Rotterdam harbour, Allseas have rented a deepwater site where Pieter Schelte will be moored and where the topsides lift system beams will be installed on the bows of the ship during the first months of 2015. A special pit needed to be dredged there for the vessel.
Offshore operations will begin in the summer of 2015 when the vessel will sail to the Norwegian sector of the North Sea, to remove the Yme platform, spanning some 72m in length and 87m in height. The vessel will use its 59 metre wide slot between bows to float in around the Yme platform and then lift off the topside weighing 13.000 tonnes in a single piece in under a minute.
