ABSTRACT
Fuel oil tanks as a part of aging bulk carriers are influenced by intensive corrosive processes which reduce strength of ships and may cause oil spillage and pollution of the environment. Quite recently, by using a comprehensive empirical data set related to the corrosion rate of considered fuel oil structure members of aging bulk carriers, the authors of this paper established the fact that among two-parameter continuous distributions, Normal, Weibull and Logistic distributions are best fitted distributions for the mentioned corrosion rate of inner bottom plating of aging bulk carriers. On the basis on the same data set, in this paper we extend the research to some well-known multi-parameter distributions. As it is expected, our comparative analysis shows that certain three-parameter distributions better follow fitted data than all other two-parameter distributions.
