Annotation:

Today, the tanker fleet transports large volumes of various types of hydrocarbons, all of which are chemically aggressive. Therefore, it is essential to ensure the proper technical condition of the vessels and their trouble-free operation. Accident-free operation requires not only compliance with navigation regulations and process charts for the storage and transportation of hazardous cargo, but also maintaining the reliability of the vessel's equipment and devices. Ensuring reliability is a key concern for oil tanker owners. Oil tankers are subject to significant loads during transportation, leading to structural wear and tear and the occurrence of various defects. This study analyzes regulatory documents governing the technical condition of oil tankers and oil cargo tanks. The paper examines the types of defects occurring in oil tanks and analyzes their frequency (based on open-source data and the results of an inspection of the Baltika tanker). The causes of defects and their impact on the reliability of the vessel's system as a whole are identified. An approach of FMEA analysis application (to assess the criticality of cargo tank defects on oil tankers) is proposed.
