Design and Refabrication of Marine Engine Alarm and Safety Monitoring System Using Arduino

Paper in proceeding, 2025

This paper introduces a cost-effective Arduino-based system for marine engine monitoring and safety control, developed as a refabrication of the Engine Control Room (ECR) for the MV Bay Cruiser. Conventional PLC- and SCADA-based systems, though reliable, are often too costly and complex for small and medium-sized vessels, creating a gap in affordable marine safety solutions. To address this, the proposed system integrates pressure, temperature, and RPM sensors with alarm thresholds, trip functions, and EOT communication into a compact microcontroller-based design. To address this, the proposed system integrates pressure, temperature, and RPM sensors with alarm thresholds, trip functions, and EOT communication in a compact microcontroller-based design. The hardware prototype was developed, tested, and validated under real operating conditions, ensuring accurate sensing, timely alarm generation, and emergency shutdown capability. Results confirm that the system delivers reliable performance while significantly reducing cost and complexity. By merging traditional marine practices with modern embedded technology, this approach enhances safety, efficiency, and accessibility, making it well-suited for passenger vessels. Future extensions may include IoT-based monitoring and predictive fault detection.
