Background
When the existing non-container ship carries the containers in the cabin, the following two ways are adopted temporarily: one is a welded embedded or protruded base, and the other is a method of binding a square wood block and a chain of a box bottom pad.
When the embedded or protruding base is adopted, the base is required to be welded to four corners of each container at the bottom layer in advance, corresponding structural reinforcement is added, the welding workload is very large, and the bottom plate of the ship is easy to damage.
When the method of binding the box bottom lining square wood blocks with chains is adopted, a large number of hard square wood blocks need to be prepared in advance so as to completely pad the bottom of the container stacking area with the wood blocks. The square timber blocks are fumigated and certified to meet the requirements of many ports for protection against biological intrusion, otherwise they are not allowed to be discharged to shore. In the mode, only two layers of containers can be approved to be stacked when the classification society approves, and at most three layers of containers can be approved to be stacked when enough binding points are arranged, so that the stacking quantity of the containers is greatly limited.
When the ship is refitted into bulk cargo or other cargos, the protruding base and the temporary binding points need to be cut off first, and a large number of cutting points and square wood blocks are very strong for sailors.
In summary, the prior art has the following disadvantages:
1) the construction amount on the ship is large, and a large amount of welding or bottom laying work is needed;
