Background
The LNG fuel tank area of the dual-fuel large container ship is special in hull structure, and the structure of related sections and total sections of the area is greatly different from that of a ship built before. For special sections with large height difference and complex structures, the arrangement and transportation scheme of the sections need to be considered again.
For the conventional step subsection, a normal laying and transporting method is generally adopted, the door frames are located at the same height, and the outer plate linear area is supported by sectional materials according to the requirement. Even if a reversed state placing and transporting method is adopted, the two door frames are at the same height and are connected and supported at the step as required. The whole states of the two door frames are consistent, and the shelving and transportation stability is good. However, for the special sections of the large dual-fuel container ship, the structural height difference is large, the structure is relatively weak, the conventional method for reversely placing and transporting the portal cross-step connecting section bars of the conventional step sections cannot be adopted for placing and transporting, and otherwise, the structure is deformed. How to effectively reduce the height difference and ensure the safety of laying and transporting is a difficult point of special sectional laying and transporting.
