Ship Engine Room Casualty Analysis by Using Decision Tree Method

Abstract

Ballast tanks have a highly complicated geometric structure consisting of several interconnected sections where transverse and longitudinal strength elements are involved. Because of this structure of the tanks, sediment accumulates in various regions within the tank and can not be discharged. The accumulation of sediment in ballast tanks can cause many problems such as the transport of invasive species, tank corrosion and cost increase in ship operation. In this study, critical zones were experimentally determined in terms of sediment accumulation in a conventional tanker double bottom ballast tank model produced at laboratory scale. The results of the study show that sediment accumulation occurs intensively around the central line.
