[0002] In recent years, the number of offshore platforms and LNG modules, which are main structures for oil and gas resource exploitation, is increasing, and the demand for site resources is increasing. For land construction, the conventional construction is carried out by using a slide resource, and after completion, the construction is completed by dragging and loading on a ship. With the increase of land construction projects, this slide construction method gradually cannot meet the project demand, mainly reflected in that the slide resource of the construction site is limited, and a new construction and loading mode is urgently needed for the project which exceeds the construction capacity of the slide resource.

[0003] The SPMT trolley construction and loading mode can well solve this problem. For the LNG module, this method is more efficient and convenient, especially for the assembly and positioning of the deck piece, and the SPMT trolley can also be used to complete the assembly and positioning, thereby saving the investment of large crawler cranes and waiting time, and the deck piece can be made larger and more perfect without being affected by the hoisting conditions. In the past, the SPMT trolley assembly and positioning process needs to replace the pad or pad pier of different heights for 3-4 times to complete the jacking and positioning of the deck piece, which consumes more labor time and forklift shifts, and is low in efficiency, which is not conducive to the progress and cost control of the project.
