Record Lift for Smit Sheerlegs
01 Sep 2002
Smit's 3,200 tonnes lift capacity Asian Hercules II returned to Norway in June to provide additional heavy lift assistance during the decommissioning of the Maureen platform.
Earlier in the year, the big sheerlegs had lifted, transported and landed 11 Maureen platform modules at Aker Maritime's Stord facility over a two week period.
For the second visit, Asian Hercules II arrived at Stord to perform three lifts, including a 600 tonne conductor frame and two lattice frames, each weighing 2,950 tonnes. The latter were the largest single lifts ever executed by a Smit sheerlegs.
To lift the extreme weight of the lattice frames, Asian Hercules II used a tailored lift configuration. This consisted of a special transverse spreader beam and four lifting blocks, to distribute the weight at 800 tonnes per block along the beam. The operation to lift each lattice frame was completed within two hours.
Asian Hercules will return to Stord twice more, with the first visit next month involving the lift of three storage tanks. The second visit, planned for December, will involve the transfer of the remaining lattice structure to the quayside.
