The length of the 11,000-12000 TEU container ship is about 400 meters, and the new generation 18000TEU Malacca Channel container ship will reach 450 meters in length.
The hull of this type is about 60 meters wide and can accommodate up to 24 rows of containers on the deck. Although some terminals are equipped with cranes that can reach the working range of 64 meters, the increase in the width of the ship will result in increased deformation of the hatch opening. The increase in the deformation of the hatch opening will have an impact on the design of the hatch cover, such as the fatigue strength of the structure at the corners of the hatch coaming. In this regard, some shipyards have introduced some innovative ideas in design, including: the use of wider spaced transverse frames, the reduction of the main support members, the removal of secondary components, etc., which will increase the flexibility of the structure. Single-hub single-host-driven container ships can have different design choices, and ABS calls it the first generation of ultra-large container ships (around 11,000 TEU). The 18,000 TEU new generation of the Malacca Straits-type ultra-large container ship is likely to use a twin-propeller dual-master drive system.
