Abstract

In 2019, ship density of Surabaya West Access Channel reached 28,112 ships. The high number of vessel densities that exist in Surabaya West Access Channel (APBS), it is possible for ship collisions to occur. In this study, Formal Safety Assessment used for ship collision Risk Analysis in Surabaya West Access Channel (APBS). Formal Safety Assessment is a structured and systematic methodology developed by the International Maritime Organization (IMO) used to conduct risk assessments and also evaluates cost-benefit assessments to get some recommendations to improve safety in the maritime world, including protection of life, health, the marine environment, and property. To achieve the above objectives, IMO's guidelines on the application should comprise the following steps; First step, Hazard Identification using Event Tree Analysis based on historical accident data. The second step, risk analysis is composed of two main activities: frequency calculating and consequence modeling. The frequency of ship collision was calculated using Traffic Based Model and for the consequence, Ansys software was used to model the structural damage of hull caused by the incident. The third step, Risk Control Option is used to get some options to prevent collisions. The fourth step, Cost-Benefit Assessment is used to identify and compare benefits and costs associated with the implementation of each RCO using Net Cost of Averting a Fatality (NCAF) and Gross Cost of Averting a Fatality (GCAF) Criteria. The last step of Formal Safety Assessment (FSA) is Recommendations for Decision-Making to get some options for mitigation.
