瘫船稳性薄弱性评估样船计算分析

摘要

IMO is now drafting the second generation intact stability criterion, one of which main parts is dead ship stability vulnerability assessment. Based on IMO SDC1/INF.6 dead ship stability failure mode vulnerability criterion draft, computation programs for dead ship stability vulnerability assessment level 1 and level 2 are developed. Calculation samples include fishery administration vessels, oil tankers, patrol ships and sea guard ships. There are three loading conditions containing load draft, design draft and ballast draft being calculated for each ship assessing the dead ship stability vulnerability. Consistency between level 1 and level 2 is studied, which provides reference to the level 2 vulnerability criterion for dead ship stability.%国际海事组织 IMO 目前正在制定第二代完整稳性衡准，其中瘫船稳性薄弱性衡准是其中的重要内容。基于 IMO SDC 1/INF.6瘫船稳性失效模式薄弱性衡准草案的相关内容，开发了瘫船稳性薄弱性衡准第一层和第二层计算程序，并进行了11艘样船计算，样船包括渔政船、油船、巡逻船、海域看护船等。对于各种船型分别进行满载、设计和压载三个吃水状态的瘫船稳性薄弱性评估，根据计算结果分析了第一层和第二层的协调性，为制定瘫船稳性第二层薄弱性衡准提供参考。
