碩士 / 國立成功大學 / 系統及船舶機電工程學系碩博士班 / 93 / Generally, the hull structures usually are made of steel, however the steel will deteriorate under the environment of the high salt and the high humidity. In order to solve the damage of ship due to corrosion, many experts have developed several kinds of linear or non-linear ship corrosion model respectively by way of material experiment、statistics data and various corrosion model. In general, non-linear corrosion model can explain the real corrosion process more than linear corrosion model. Therefore, the non-linear corrosion model is used in present investigation.
In this study, the new time variant non-linear ship corrosion model is proposed and other two kinds of corrosion models are used to evaluate the corrosion effects on ship plates. A double hull bulk carrier is selected as an example to exam the method of FORM and SORM. The reliability index of the ship structure under various failure modes is studied. In addition, different recording periods are also considered, the comparison of corrosion reliability between the ship with stationary repair period and the ship without any repair is presented.
