Safety Analysis of Barge Maneuvers in Restricted Port Area

Abstract

This paper provides a case study on manoeuvring safety analysis of barge in a restricted area. A developing port is intended to handle barge having the capacity of 10.000 DWT. The port basin is enclosed by wharf and jetty belonging to two companies. A halflength of the new wharf is blocked by the existing jetty. The jetty located at entrance of wharf basin has a possibility to be crashed by the barge. This research is aimed to analyse the safety index and collision probability of the barge at the area. Maneuvering simulation is developed by using Mathematical Maneuvering Group (MMG) model to determine the number and capacity of required tugboats. The safety index is calculated based on Environment Stress method and the probability of collision is analysed using the predicted path of the barge. The result of simulation shows that manoeuvres are at a critical condition of safety index and required tugs capacity is higher than the requirement of the authority.
