Abstract: Imagine a single wearable device that could track where everyone is on a ship, instantly detect if someone falls overboard, and control who can access restricted areas— all at once. This research paper presents exactly that: an integrated wearable apparatus designed to transform maritime safety. The device combines advanced positioning technology (GNSS receivers), motion sensors (Inertial Measurement Units), water detection sensors, and secure biometric access control into one waterproof, lightweight wearable. Instead of using fixed geographic boundaries, the system creates dynamic three-dimensional zones that move with the ship—keeping safety boundaries relevant no matter where the vessel travels. When someone enters the water, a hydrostatic pressure sensor immediately detects the submersion and triggers alarms on both the device and at the control center, dramatically cutting response times for man-overboard incidents. A key innovation is the tiered access control system: crew members can be granted permission to enter engine rooms and restricted machinery spaces, while passengers are kept out of dangerous areas. If a passenger attempts to go where they shouldn't be, the system alerts security—all automatically. Unlike older systems that require multiple separate devices (trackers, emergency beacons, access cards), this wearable consolidates everything into one solution that crew can't forget or lose. Testing through detailed simulation shows remarkable results: the positioning system pinpoints location within 1.8 metres even inside a large ship, water submersion is detected and reported within 2.3 seconds, and the biometric authentication is nearly flawless. Compared to traditional manual emergency beacons that rely on someone pressing a button during a crisis, this automatic detection reduces response time by 94%—a difference that can mean the difference between survival and tragedy in cold-water emergencies. By bringing together real-time location tracking, automatic emergency detection, and security management in a single compact device, this innovation eliminates equipment fatigue, improves emergency response, and creates a new standard for maritime safety. It's a system designed with one goal in mind: bringing everyone home safely.
