Daily Log Sheets  

Many of you are already documenting the performance of your NGV refueling stations. This provides you with a daily history, a means of comparing past performance with the present with an eye on future performance. 

We encourage our customers to fill out log sheets on a daily basis. In one instance we had an individual that had never seen an NGV station before but was responsible for filling out the log sheet. We marked each point alphabetically for them and keyed this into our log sheet. Within weeks he could log the station in less than 10 minutes and was able to identify problem areas!

If you are not already completing daily checks of your NGV refueling station and recording your findings on a log-sheet, you may wish to start today! This information will prove most helpful in the efforts to keep your station up and running.

A daily log-sheet is simply a form that an operator completes on a daily basis by examining the station instrumentation and recording the findings. Some of these check points include:

• Inlet Pressure

• Discharge Pressure

• Inter-Stage Pressures

• Oil Consumption

• Discharge Temperatures

When compared against past performance the operator can determine if there might be a problem developing. This ability to compare and predict is the foundation of Planned Preventative Maintenance.

There are a number benefits to this type of maintenance approach. First and foremost the station is kept on-line satisfying the customers that depend upon the station. Second it allows for more economical repairs. Parts can be ordered and shipped via regular means and repairs maybe be scheduled for regular working hours. Both save money.  (see our compressor parts page)

Another benefit is the increased safety of the station. A station that is maintained on a daily basis is less likely to experience a catastrophic failure than one that is neglected.

One aspect of maintenance that is often overlooked is station cleanliness. Clean equipment not only looks nice, but it also tends to show leaks much more quickly than dirty equipment. Clean equipment tends to send the message to both customers and supervisors that the personnel responsible for maintaining a site are doing exactly that

We have included a sample log-sheet that has been developed by Ingersoll Rand for their CNG compression packages. 


Here is a log sheet that we would suggest using.   Log Sheet
