为获得安全、可靠的初稳性高度(GM)最小限值，基于船舶稳性和甲板装载特重大件稳定性要求，针对船舶处于静水和波浪中两种情况的计算分析，得出具有通用性的初稳性高度理论限值计算公式.以一艘半潜船载运特重大件的实际情况为例，运用该公式计算其初稳性高度限值，结果验证了该初稳性高度限值计算方法的合理性，为半潜船载运特重大件时初稳性高度限值的合理确定提供了一种新方法.
Abstract
To obtain safe and reliable metacentric height (GM) minimum limit, the paper analyzed the GM limit in static water and waves based on vessel stability and stability requirement for deck loading special heavy cargo, and the versatile GM limit formula was got. Taking a loaded semisubmersible vessel for example, the GM limit was calculated by using the proposed formula. Results verify that the GM limit formula is reasonable, which can provide a new method for determining reasonable GM limit for semisubmersible vessel carrying heavy bulk.
