Project Description

After 25 years of operation, the Maureen Alpha platform was closed. The whole stucture, weighing some 105,000 t, was moved from its location in the North Sea to an inshore position just off Stord island.

The heavy base will form part of a new quay wall. A floating crane lifted off all the top modules, except for the flare tower. Then the Hi-Deck was demated from the substructure onto a barge and brought to the quayside in Stord.

Here VSL Heavy Lifting started its work. The massive
12,000 t  deck was skidded over a distance of 90 meters onto the wharf for dismantling. With 4 of our strand pulling units SLU-330, a launching speed of 12 m/h was achieved. With the smaller draft due to the reduced weight, the platform was then moored about 2 km away from shore. There the upper part of the substructure was removed. The remaining base 40 m high and weighing about 66,000 t, were left at the end of this operation.

The challenging part was now to separate the 3 storage tanks from the lattice frame.
