Major Faults Accurately Pinpointed on Naval Ship Engine During its Operation with Engine Condition Monitoring System by Neptunus
Highlights Of Our Product
Easy To Install And Operate
Pinpoint emerging defects
Remote monitoring of all assets under a single central command,
Increased uptime of engines
Scientifically Extend Overhaul Intervals with Significant Cost Savings
- 8 MPU Sensors were installed to monitor health of the Port and Stbd main engine & torque of the individual propeller shafts
- The diagnosis was done in a dual-cylinder setup due to the absence of provision to mount a TDC sensor on the cam gear.
- Data stored in Vib360: engine condition monitoring system , can be periodically downloaded for trend analysis.
- The system was installed and monitored by Naval Command for over six months for the evaluation process.
Discovery/Insights From Our System
Some issues highlighted by the system during the trial period are described below
- Operating efficiency is high at higher loads as compared to lower loads
- Power loss at low loads is 2.3% and 0.9% at high loads.
- Significant torsional twist on the crankshaft is observed during low loads and idling (359 RPM), indicating non-uniform power strokes
- Compression issues on cylinders observed – due to worn piston rings & fuel leakage
The Diesel Testing & Tuning Team (DTTT) in Mumbai and Visakhapatnam have each started the process on Gem to purchase one portable box and added it to their regular tool list. Data from every engine on every war vessel would be obtained once a month for analysis, trending, and alarms for years, and the permanent installation of the tool on all the naval engines would be decided based on its performance.
