Monday September 15th the Muller owned pontoon 10033-1 arrived in Vlissingen with the base part of a testframe.
The frame is to be fabricated and modified by Volker Staal en Funderingen for testing parts of the capabilities of the Pioneering Spirit. The Muller tug En-Avant 20 towed the pontoon from the Able yard in Teesside (UK).
Last week the frame (weight around 1,500 tons) was rolled onto the pontoon using SPMT's (self propelled modular transporters).
Before the Roll-On the construction of the seafastening and support beams was modified to suit the different layout of the pontoon compared to the pontoon when it was delivered at Able.
VSF also supplied the seafastening and the supportbeam for the pontoon, this mobilization took place at Moerdijk.
In Vlissingen the frame will be devided into 2 pieces and modified. After modification the frame will have a height of almost 60 meters. For the installation at sea 4 suction anchors will be attached at the bottom of the frame. The suction anchors will be fabricated by VSF at our yard in Rotterdam.
For the testing of the lift systems for the giant and world’s largest decommissioning vessel ‘Pioneering Spirit' (measuring 382 meters long and 124 meters wide and suited for lifting of structures weighing up to 48,000 tons), Allseas has awarded the fabrication of a Test Frame to the project joint-venture of SPT Offshore and Volker Staal en Funderingen. Both companies are part of the VolkerWessels group.
The test frame will exist a lower part founded on 4 suction piles and an upper part which will include a ballasting device. This will be filled with sea water in order to simulate a test lift weight of 5,000 tons.
The test frame is planned to be completed in the first half of 2015, after which it will be installed in a field in the Dutch sector of the North Sea in a water depth of 30 meters.
