Abstract (Abstrak)

Nowadays, the container transportation service increases rapidly and then this condition emphasizes the container ship growth. The containers stowage only on deck can cause a serious problem subjected to ship stability. The objective of present study is to analyze the stability of a container ship due to containers stowage on deck. Also, twelve cases based on weight conditions C1 to C2 were simulated in order to distinguish the impact of the weight on stability parameters KG, GZ, vanishing stability angle, and stability range. The results show the weight condition affects on the magnitude of KG and LCG wherein the position of centre of gravity point is behind amidship and the decrease of LCG due to the decrease of consumable weight ≥ 50% is average 2.06%. The effect of the decrease of consumable weight ≥ 50% can make stern trim condition (C3, C5, C6, C8, C9, C11, and C12). The containers stowage on deck impacts on reducing the KG as well the magnitude GZ becomes small. In addition, the vanishing stability and stability range become small. Nevertheless, the stability parameters due to the containers stowage on deck fulfil the requirement of Intact Stability Code. Overall KG values due to the weight condition (C1 to C12) are significantly lower than the limiting KG. This means that overall KG due to weight conditions fulfill the stability criterion.
