A checklist for setting up your CNG fueling facility maintenance
A well-planned and executed maintenance program is key to the reliability of your CNG Refueling Station. Not only will your station be on-line, all the time, it will also be safer for those fueling and those working at the station.
Here is a quick checklist that will help you get you started.
- Identify the sequence of operation.
- Determine the actual sequence of operation.
- Make corrections to operations required.
- Select onsite personnel to be responsible for daily maintenance. Then provide the training and time to perform the job properly.
- Set up and use a log sheet to track equipment performance.
- Keep wiring diagrams, flow schematics and OEM manuals onsite. They are much more useful there for troubleshooting purposes than sitting on a bookshelf miles away from the station.
- Check OEM maintenance schedules and draw up a plan to carry out required maintenance procedures. Document these procedures when they are completed.
- Test all equipment safety controls on a regular basis to verify their proper operation. Document these safety checks.
- If you do not have personnel within your organization qualified to troubleshoot the station equipment, contact qualified, reputable service companies and check the cost of having them run a regular maintenance check on your station. Specify what equipment checks and maintenance procedures you want carried out. Also, request that they state any additional checks they believe should be made. A standard simplex compressor with priority sequencing with a gas dryer and a dispenser can easily require an entire day to PM.
- Have your gas tested for water content (dewpoint testing) so possible freeze-up problems can be identified. Take dewpoint readings at the suction side as well as the discharge. Plan to stock a minimum of spare parts, such as gasket kits, O-rings, valve rebuild kits, control relays, etc. These should be kept onsite so minor repairs can be done with a minimum of downtime.
