摘　　要：考虑到服役船舶使用过程中腐蚀损耗会使船体构件的几何尺寸缩减,使得船体结构强度减弱,以SL151起重船为例,对服役船舶的主要构件进行强度计算分析。在不更换结构板材的前提下,采取局部结构加强方案,进行对比计算分析。结果表明,可以通过局部结构的加强达到抵抗腐蚀等因素造成的结构强度损失。Due to the corrosion loss in the using progress of the service ship, the geometric dimensions of hull components will be reduced. As a result, the hull structure strength will be weakened. Analysis of the main components strength of service ship named SL151 crane was carried out to study the effect of the local structure strengthening on the premise of not replacing the structure panels. The results showed that strengthening the local structure can resist the loss of structure strength caused by the corrosion.
