Early Detection of Fan Instability in Marine Engine Room

This technical report outlines the critical role of the engine room ventilation system in marine operations, emphasizing the importance of maintaining reliable operation to ensure safe and efficient vessel performance. The report details findings from an inspection conducted by AVT Reliability engineers, who observed visible wobbling in the fan and signs of wear on anti-vibration mounts. Vibration analysis revealed multiple harmonics, indicators of imbalance, and signs of possible looseness, suggesting a combination of issues affecting the fan's operation. The report presents a structured set of recommendations for addressing the identified problems, including replacing worn components and conducting inspections to prevent further degradation. Additionally, it highlights the proactive maintenance planning enabled by early fault identification, which helps avoid potential failures that could impact engine room ventilation and overall vessel operation. The findings are documented through the Machine Sentry platform, which aids in ongoing condition monitoring and supports marine operators in improving asset reliability.
