River ports have a major role in the export, import and national trade activities of sea lanes. With these conditions, it causes a heavy flow of ship traffic in the River Shipping Channel. The density of ship traffic makes it possible for ship accidents to occur at the River Port. The study in this study is to determine the level of risk from the consequences of a ship accident with a Jetty based on a river current that has a speed of 2.0 knots. So that the possible speed of the ship when there was a loss of control that hit Jetty was 2.0 knots. In this study, the analysis of the risk of ship collisions at the Sungai Harbor uses the DNV GL 2015 Risk Matrix standard. Hazard identification uses the brainstorming method from the DNV and KNKT investigations. Frequency analysis using Bayesian Network model which is applied to Hugin Expert software. The effect analysis is calculated by modeling the ship and Jetty due to the collision using the Ansys software. The value of the frequency of ship collisions using 3 (three) scenarios with the results of the frequency of each scenario is 0.0638, 0.0285, and 0.0285, respectively. Consequences are calculated by simulation using Ansys software by modeling ship and jetty collisions. The simulation results show that there is damage to the hull of the ship. The estimated cost of repairing the hull is IDR. 587.612.250,00. The risk matrix used is the 2015 DNV GL standard so that the risk level after the analysis is in the Tolerable category.
