Savannah Harbor is located on the eastern shore of the state of Georgia. The harbor is being evaluated for deepening and widening. The purpose of the proposed improvements is to accommodate larger, deep-draft containerships to use the port. The widening is being considered to provide additional room for two-way traffic. To evaluate these improvements a real-time ship simulation study was undertaken. Simulation models were developed for both Savannah's present and future conditions. Pilots from Savannah Harbor operated the simulator as they would in real-life. Eased upon these simulations, a final improved channel was developed.
