Description

Technical Field

[0002] When a 1t standard container is transported by sea, it is generally connected to the deck or between boxes by means of pre-installed corner pieces, twist locks, lashing rods, etc. on the four corners. The fixing method is that a single container is fixed by itself in the horizontal plane, and multiple layers can be stacked in the vertical direction. Due to the small size of 1t containers, when fixed in the above method, when non-dedicated ships such as multi-purpose cargo ships or roll-on / roll-off ships are used for transportation, a large number of container fixing bases need to be installed on the cargo hold deck, the workload of modification is large, and the lashing time is long. In addition, lashing space and passages need to be reserved between each container, and the number of containers that can be loaded is small, which occupies more lashing resources on the ship and cannot fully utilize the loading hold space.

[0003] Therefore, there is an urgent need in the art for an efficient container lashing solution suitable for multi-purpose cargo ships or roll-on / roll-off ships. Summary of the invention

A plurality of mooring holes 11 are arranged in a matrix on the hull 1 of the multi-purpose ship cargo hold or ro-ro ship. The mooring holes 11 are tied with lashing members 2. The lashing members 2 include but are not limited to the original mooring rigging or lashing belts on the hull 1, and the method comprises the following steps:
