针对老龄舰船船体结构评估问题，首先引入了中国船级社2011版《现有船状态评估程序指南》；然后，论述了老龄舰船的腐蚀特点及腐蚀程度测定方法，并给出了剩余剖面模数计算方法。再以某舰船为例，依据该指南对其典型舱段总纵强度状态进行了评估；最后，运用ABAQUS有限元软件直接对该舱段的现有状态总纵强度进行了计算并与《现有船状态评估程序指南》得出的总纵强度状态评估结果进行了对比分析。结果表明：该指南对于老龄舰船技术状态评估具有良好的可行性和适用性。
針對老齡艦船船體結構評估問題，首先引入瞭中國船級社2011版《現有船狀態評估程序指南》；然後，論述瞭老齡艦船的腐蝕特點及腐蝕程度測定方法，併給齣瞭剩餘剖麵模數計算方法。再以某艦船為例，依據該指南對其典型艙段總縱彊度狀態進行瞭評估；最後，運用ABAQUS有限元軟件直接對該艙段的現有狀態總縱彊度進行瞭計算併與《現有船狀態評估程序指南》得齣的總縱彊度狀態評估結果進行瞭對比分析。結果錶明：該指南對于老齡艦船技術狀態評估具有良好的可行性和適用性。

For the condition assessment of the hull structure of an aging naval vessel ,the Condition Assessment Program of Existing Ship published by the CCS in 2011 is used to describe the corrosion characteristics and grades of the aging naval vessel ,and a method of calculating the remaining section modulus is proposed . With some a vessel as an example , the typical compartment′s longitudinal strength condition is assessed according to the Condition Assessment Program of Existing Ship ,and then the FEM software ABAQUS is applied to calculating and analyzing its current condition directly . T he tw o kinds of evaluated results are compared .T he result indicates that the application of the Con‐dition Assessment Program of Existing Ship to the condition assessment of aging naval vessel′s longi‐tudinal strength is feasible and applicable .
