Corrosion Modelling of Single Hull Crude Oil Tanker Subjected to Multiple Deterioration Environments

Abstract

This work aims to study the corrosion deterioration of crude oil single hull tankers, considering the corrosion degradation process from both the internal and external sides of plating. The corrosion degradation of the external side of the tanks is modelled as corrosion degradation under atmospheric conditions or under immersion conditions or under repetitive atmospheric and immersion conditions, depending on the location of the plate elements. The corrosion degradation of the internal side of the crude oil tank is estimated as corrosion under tank environment considering the chemical and physical conditions of the crude oil. The different corrosion deterioration mechanisms under the different environments and the corresponding factors affecting it are modelled based on recently proposed models.
