Dongnan Intelligent O&M System delivers real-time condition monitoring and predictive maintenance for marine engine room equipment. It replaces scheduled maintenance with continuous data collection, health profiling, and early fault alerts. By fusing vibration, oil, and displacement data with intelligent diagnostics, the system detects degradation early, informs maintenance decisions, reduces unplanned downtime, and boosts operational efficiency.
Intelligent O&M System
——
Vibration Monitoring
Vibration sensors are installed on cylinder heads, crankcases and turbochargers. Spectrum analysis identifies faults such as rotor imbalance, mechanical looseness and gear wear.
Oil Condition Monitoring
Continuous monitoring of lubricating oil and hydraulic fluid quality, tracking wear particles, moisture and viscosity to detect contamination and abnormal wear promptly.
Shaft Displacement Monitoring
Eddy current displacement sensors monitor main shaft status, analyzing shaft center trajectory and eccentricity to detect abnormalities such as shaft bending and oil film instability.
System Hardware Architecture
Redundant servers, data acquisition gateways and industrial communication networks ensure stable data acquisition and transmission, supporting long-term continuous operation and storage.

Reducing Downtime Risk
Through real-time data comparison with historical baselines, the system provides early warning before critical failures, prompting proactive maintenance and reducing unplanned downtime losses.
Controlling Maintenance Costs
Maintenance plans based on actual equipment condition avoid over-maintenance and unnecessary spare part replacement, reducing labor and spare part costs by approximately 15%-25%.
Extending Equipment Lifespan
Early warning and timely intervention prevent equipment deterioration from escalating into cascading damage, extending critical equipment service life by approximately 10%-20%.
Enhancing Asset Value
Complete traceable digital O&M records improve vessel operational management, enhance market competitiveness and residual asset value, increasing asset value by approximately 5%-15%.
