A STUDY THE EFFECT OF CORROSION ADDITION ON THE SHIP STRENGTH

Abstract

The corrosion addition is applied to the entire ship hull structures and is specified in the regulations of the classification societies or the rules of the International Association of Classification Societies (IACS). The values of corrosion addition are large, which lead to increasing the ship’s lightweight, increasing the cost of new construction, reducing the ship's cargo capacity, etc. This paper will evaluate the longitudinal ultimate strength and the changes in the transverse cross-sectional properties of a bulk carrier and an oil tanker when reducing the value of the corrosion addition. The results for these two mentioned issues will be introduced, evaluated, and used as a basis for making recommendations on reducing the value of corrosion addition.
