腐蚀速率的准确估计在确定结构设计的腐蚀裕量、检查计划和维护计划中起着重要作用。本文根据140艘单船体的11万多个壁厚测量数据库，对油船结构件的腐蚀速率进行了估算。腐蚀速率可以通过威布尔分布函数来描述。平均值，标准偏差和最大值的结构构件的腐蚀速率的基础上获得的整个人口的数据库。并与油轮结构合作论坛（TSCF）公布的腐蚀速率范围进行了比较。该研究旨在更新有关钢质船舶腐蚀速率的知识，并为减轻腐蚀风险做出贡献。Copyright © 2003 by ASME
An accurate estimation of corrosion rates plays an important role in determining corrosion allowances for structural designs, planning for inspections, and scheduling for maintenance. This paper presents an estimation of corrosion rates of structural members in oil tankers based on a corrosion wastage database of over 110,000 thickness measurements from 140 single hull oil tankers. Corrosion rates may be described by a Weibull distribution function. Mean, standard deviation and maximum values of corrosion rates for structural members are obtained based on the entire population of the database. They are compared with the ranges of corrosion rate published by Tanker Structure Co-operative Forum (TSCF). The study aims to update knowledge on corrosion rates in steel ships, and to contribute to the efforts of mitigating the risks of corrosion.Copyright © 2003 by ASME
