AN APPROACH TO THE PROBABILISTIC CORROSION RATE ESTIMATION MODEL FOR INNER BOTTOM PLATES OF BULK CARRIERS

Abstract

This paper gives an approach to the probabilistic corrosion rate estimation model for inner bottom plates of bulk carriers. Firstly, by using the data from thickness measurements for inner bottom plates for considered 25 bulk carriers, the related best fitted linear model for the corrosion wastage is obtained as a function of ship's age. In this model it is assumed that life of coating is 4 years. The obtained related corrosion rate is equal to 135474 . 0 mm/year. Notice that the obtained linear model is a particular case of a power model proposed in some earlier investigations.
