A NEW DESIGN OF CONTAINER CARRIERS FOR MAXIMIZING CARGO CAPACITY

摘要

This paper introduces SkyBench container carrier which Hyundai Heavy Industries Co. is developing first in the world. SkyBench container carrier which overcomes the limitations of space utilization using mobile concept at superstructure provides the owners with maximized utilization of space through loading more cargoes compared with the similar size of conventional design. There are many advantages in addition to the increase in cargo capacity. Better stability and increased loadable capacity in the design aspect can be achieved through rearrangement of compartments. For the global hull girder strength, reduction in still water bending moment and its relevant positive effects can be possible. Better habitability and reduced degree of fatigue can also be achieved through SkyBench's unique vibrational and noise characteristics. On the contrary to the advantage, there may be a disadvantage of larger structural response in hatches and benches caused by torsional moment due to an additional hatch opening, which can be controlled within permissible range through a reasonable design of side towers and lashing structures. Finally, a new survival concept with an automatic separation of mobile part from its supporters in an accidental limit state is introduced.
