Machine condition monitoring has a critical role to play in identifying problems in machineries by detecting variations in sound and vibration. By identifying such problems before there is a major machine malfunction or breakdown, productivity and availability of machineries can be enhanced. The time for maintenance is determined by a change in the pattern of vibration or sound. Continuous machine condition monitoring boosts equipment efficiency and reduces maintenance downtime, which is vital for critical components. A complete database is maintained of the ship’s critical machineries. The Machine Condition Monitoring system results in significant savings, not only maintenance and downtime related, but also via energy conservation.
