摘要

针对载有重大件货物的半潜船在长波海浪中航行时具有发生参数横摇的风险,构建半潜船的运动模型,找出诱发半潜船参数横摇的关键因素.然后,运用变参数分析法定量计算分析波浪长度、波浪高度、初稳性高度和航速变化等关键因素对半潜船航行安全的影响程度及作用规律.最后,基于案例分析,获得半潜船不发生参数横摇时各关键因素取值区间.该问题的研究有利于推动半潜船稳性规范的完善与统一.

Abstract

A semi-submersible vessel’s motion model was constructed in order to find out the key factors to induce the parameter rolling for semi-submersible vessels carrying heavy cargo in the long waves. Then, the variable parameter analysis method was used to quantitatively calculate and analyze the influence degree and rule of the key factors including the wave length, wave height, metacentric height and speed variation on the navigation safety of the semi-submersible vessels. Finally, based on the case analysis, the critical interval values of semi-submersible vessels without parametric roll are obtained. The study of this problem will help improve and standardize the stability criterion of semi-submersible vessels.
