The use of Pareto-Lorenz analysis for the determination of faults in fishing vessel refrigerating systems

This study is aimed at the determination of the significance of faults diagnosed in refrigerating plant components of fishing vessels. The problem is described by the Pareto-Lorenz analysis. The field work covers vessels of the Polish fishing fleet. Ships under examination are typical of the Polish fishing vessels operating at sea. The research has been based on data gathered in 2007–2011, consisting of 235 faults, detected and estimated for refrigerating systems of 25 small vessels of the Polish fishing fleet. Taking the refrigerant as a criterion of division, we have analyzed two types of vessels.
