PSA is considering new types of drones that fly autonomously through software controlled flight plans through their integration with Internet of Things (IoT) technology. Drones can be used to fulfill ship-shore or shore-ship deliveries. Working with on-ground IoT sensor networks, drone surveillance can also help with terminal security, providing an easier, faster and cheaper method of data collection.Inspections are also a major application for drones, says PSA. These can range from a basic port equipment structural inspection requiring images of a crane structural joint, to the complex inspection of an energy installation in the port infrastructure. PSA is also looking towards the development of amphibious drones that can operate over and land on water to inspect wharf side fenders.
