JIEXI marine service team carried out overnight emergency repair for vessel engine room alarm & monitoring system at Maoming Port. Our engineers boarded the ship at midnight, diagnosed faults and finished full repair before 5:00 a.m., helping the vessel resume normal monitoring function and avoid schedule delay.

Case Background
During a port call at Maoming Port, the vessel experienced a sudden failure of its engine room alarm and monitoring system. This system is a core safety system in the engine room. It monitors the main engine and auxiliary machinery in real time, including temperature, pressure and liquid levels, and triggers visual and audible alarms. If the system fails, the vessel cannot safely proceed with its planned departure and may face risks during PSC inspection.
After receiving the emergency request, JIEXI arranged for experienced service engineers to board the vessel immediately at midnight. The engineers carried out a systematic inspection, tested signal loops, and troubleshot the modules and communication functions of the alarm and monitoring system. After continuous overnight work, they located and repaired the root cause by 5:00 a.m. A full functional test was then carried out to confirm that all alarm channels, data display and alarm response were working normally.
Challenges
- Severe Time & Demurrage Pressure: The sudden breakdown occurred during a limited port stay at Maoming Port. Any delay in troubleshooting could directly lead to missed sailing schedules and heavy financial demurrage for the shipowner.
- Arduous Overnight Operations: The service required midnight emergency dispatch and continuous overnight technical work in the engine room under extreme time constraints and challenging off-hour conditions.
- High Technical Sensitivity: Engine room AMS fault diagnosis is highly complex. Inaccurate diagnosis or misoperation could easily aggravate system faults, affecting broader engine room parameters and communication loops.
- Strict Regulatory & Compliance Standards: As the core safety monitoring system for main/auxiliary engines, liquid levels, and pressure alarms, the repaired AMS had to pass 100% functional verification to meet Class society and PSC inspection requirements.
Solution
- Midnight Rapid Mobilization: Arranged senior marine automation engineers to board the vessel immediately at midnight upon receiving the emergency request from Maoming Port.
- Systematic Multi-Point Fault Isolation: Executed thorough inspection and testing across hardware modules, signal loops, I/O parameters, communication lines, and sensor channels of the alarm system.
- On-Site Component Repair & Reset: Completed module troubleshooting, component replacement, communication recovery, and system parameter resets overnight to eliminate root causes by 5:00 a.m.
- Full-Scope Simulation & Functional Testing: Conducted comprehensive post-repair testing to verify real-time data display, signal response, and audible/visual alarm channels for all engine room monitoring points.
- Formal Service & Class Documentation: Issued a complete technical handover and service report for the Chief Engineer's records and official Class/PSC inspection submission.
