Enhanced Personnel Sea Safety Technology Demonstrator
In plain English
AI plain-English summaryA lifejacket that alerts a ship the instant someone falls overboard, then tracks their exact position without GPS, could cut rescue times from minutes to seconds. Every year, people die at sea because crews do not realise someone has gone overboard until it is too late. Existing systems rely on GPS, which can fail or take time to acquire a signal. This project demonstrates a low-cost alternative: a small module worn in a lifejacket or attached to equipment like shipping containers. It works with an electronic geofence around the vessel. When a person or object crosses that boundary, the system triggers an instant alert and continues to track their position in real time using a non-GPS method. It can monitor multiple modules simultaneously. If successful, the technology could reduce lives lost at sea—both commercial and leisure—by enabling the fastest possible rescue from the mother vessel. It also helps recover lost cargo, warn other ships of hazards, and reduce environmental damage from drifting debris. The system is designed to be cheap enough for widespread adoption, potentially changing how maritime safety is managed across the industry.
