Crew Safety Aid (CRESAFA): A Modified Technological System for Efficient Man Overboard Recovery and Distress Sending
Year: 2025
Type: article
Abstract: The research creates an updated technological framework that evaluates man-overboard recovery skills and distress signal capabilities. The system utilizes real-time tracking, distress signal transmission, and water detection features, which operate optimally in both calm and rough environmental conditions. The study employed an experimental approach using an Arduino-based system that underwent testing without initial functionality assurance in both open sea and freshwater locations. Three maritime experts confirmed the results through validated Key Performance Indicators (KPIs). According to the researchers' KPI, the CRESAFA system demonstrated outstanding proficiency in peaceful waters. The victim-tracking capability of the system achieved proficient levels during challenging conditions before showing further improvement in subsequent trials. The system provided immediate distress signal transmission, precise coordinate readings, and dependable wireless communication throughout all tests. The system achieved outstanding results in optimal conditions, yet its performance in rough environments suffered from power limitations. The research demonstrates how the system can enhance maritime safety and operational efficiency, particularly during man-overboard emergencies, while also revealing its performance strengths and weaknesses under various environmental conditions.
