摘要
和其它类型船相比,半潜船的工况更复杂,船舶型线和用途也很特殊,使得稳性问题成为设计中一个重大的挑战。但目前还没有针对该类船舶的稳性规范,对该类船型开展稳性研究很有必要。通过1艘改装半潜船的稳性计算,发现航行状态下半潜船稳性特征与江船类似。而在下潜状态下,稳性随吃水增加而有所好转,在货物甲板出入水时稳性最差,此时可以采用纵倾来改善稳性。同时建立了依据完整稳性的船舶装载能力的数学模型。
Semi-submersible vessel has more complicated working conditions compared with other ships, with special lines plan and purpose,which makes the stability a big challenge for designers. In this paper, the intact stability of a conversion semi-submersible vessel was calculated to reveal the intact stability properties of this ship type. The character of the stability on the navigation condition is similar to the river ship. A stability catastrophe point exists as the draft of the vessel equal to the mould depth, also known as the intact stability poorest point, making it a potential threat to the safety of the vessel and cargo. The loading ability of the vessel was obtained by the mathematical model.
