| Abstract: | A support structure with adjustable air gap is designed for dismantling the large offshore oil field facilities by combined lifting with Twin Marine Lifter (TML). The structure is easy to install and disassemble, and is of low requirements on the hull draft performance of construction ships. The finite element model of support structure is established, the strength check and buckling check are made, and the stress distribution of support structure and the utilization rate of each link are given. The design scheme and analysis method can provide reference for the design of special equipment for dismantling large offshore structures. |
