Port safety assessment are primarily conducted only on large ports despite the essential roles of small multipurpose ports for archipelagic areas such as east Indonesia. It is important to note that the increase in the activities of the small port is causing an increased risk of accidents. The study aims to assess the risk of accidents at small multipurpose ports. The safety assessment model applies the Formal Safety Assessment (FSA) method of the International Maritime Organization (IMO) and the use of As Low As Reasonably Practicable (ALARP) with adjusting conditions in a small multipurpose port. The expert judgment method supported by study literature, Focus Group Discussion, interviews, observation, and onboard is carried out to obtain data. Validation of risk identification with Eigen index and risk assessment supported by AHP and FTA weighting methods. This study found that incidents of burning ships and human accidents, i.e. people falling off ships or docks, being hit by vehicles, and being hit by mooring line throws, were the highest risks in small multipurpose ports. Cost-benefit analysis using Cost of Averting Fatality (CAF) that several recommendations are obtained to overcome various accidents at small multipurpose ports, which in essence, is accountable and easy-To-implement system work. © 2023 WITPress.
