Pieter Schelte, the 382 metre long and 124 metre wide dynamically positioned giant is specially constructed for decommissioning of offshore installations, such as removal of platform decks.
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. The lifting process will according to the decommissioning plan be completed in under one minute (about eight seconds). The new technique does not involve jacking down of the rig, which results in significant savings.
The vessel will conduct extensive testing in the Netherlands before heading to the North Sea. Edward Heerema, owner of the Swiss based Allseas Group, says that the decommissioning of Yme will be a demanding task.
“This will be a difficult test because the platform will be so unstable due to weaknesses in the design”, he said to OE Digital earlier this fall.
Pieter Schelte is also planned to assist in the decommissioning of Shell’s three platforms in the Brent field on British sector of the North Sea.
Norway’s Norsafe today announced it has delivered twelve JYN100 conventional lifeboats and two fast rescue crafts for the giant Pieter Schelte.
The Norsafe JYN100 is a conventional Totally Enclosed Lifeboat (TELB) which is designed and built in accordance with the latest NORSOK R-002 standards, with a capacity of 106 persons. The advanced hydraulic davit systems are specially designed for Pieter Schelte.
“This confirms Norsafe’s versatility and ability to supply life saving appliances (LSA) to all of the World’s most advanced vessels and offshore installations”, says SVP Sales and Marketing Kjell Soerensen in Norsafe Group.
“We know that safety must be a top priority when such tasks are conducted. It is therefore a vote of confidence that our lifesaving systems are preferred for this vessel”, says Soerensen.
