This paper simulated a simultaneous un-berthing of two container ships. The simulation was intended to determine the number and capacity of tugboats considering an emergency situation in a port. A port provides the number and capacity of tugboats based on the regulation of the Transportation Ministry. In an emergency condition at the terminal and the maximum environmental conditions of wind, wave, and current, the vessel should be un-berthed simultaneously. In this study, two container ships are un-berthed simultaneously in eight scenarios. The available tugboats are simulated using the MMG model to pull the vessels from the jetty turn them in the approaching channel and pass the main channel to achieve the anchorage area. The trajectories of maneuvering using the existing tugs are compared to the normal passage using the appropriate capacity of tugboats. The number and capacity of the tugboat to comply with the safety criteria and avoid collision between the un-berthed ships is proposed.
