Risk analysis of ship detention defects based on association rules

Abstract

Port State Control (PSC) can effectively improve crew and ship safety, reduce the probability of maritime accidents, and prevent marine environment from being polluted, playing a key role in the international shipping market. In order to effectively identify the degree of influence of various defects on the main types of ships in PSC inspection, a risk assessment matrix is constructed in this paper to determine the risk level of each detention defect. In addition, considering the association between various detention defects, this paper uses the CARMA algorithm to mine the association rules between various detention defects, so as to identify the defects that cause a higher risk of ship detention. The results show that for the existing six main ship types, Fire safety, Safety of Navigation, Life saving appliances and ISM have higher risks of ship detention and the risk of a ship being detained by a defect varies for different types of ships. In addition, corresponding recommendations are provided for port state control officer (PSCO) and ship managers to ensure ship safety based on the risk of deficiencies. This paper has reference value for shipping companies to effectively manage ships and improve the efficiency of port state inspection.
