TELEDYNE PDS - Port Entrance Simulation (PES) is a unique software tool to ensure safe navigation for vessels from entrance of the port to their berth. A Port Entrance Simulation (PES) package allows port authorities and pilots making decisions on vessel management in their ports. TELEDYNE PDS-PES is the tool to verify that vessels can safely navigate in and out the port using the latest collected survey data. It simulates the route the vessel has to sail and indicates any areas that are too shallow. Tidal information and the shape and draft of the vessel are taken into account in the calculation as well.
