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.

  1. Identify the sequence of operation.
  2. Determine the actual sequence of operation.
  3. Make corrections to operations required.
  4. Select onsite personnel to be responsible for daily maintenance. Then provide the training and time to perform the job properly.
  5. Set up and use a log sheet to track equipment performance.
  6. 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.
  7. Check OEM maintenance schedules and draw up a plan to carry out required maintenance procedures. Document these procedures when they are completed.
  8. Test all equipment safety controls on a regular basis to verify their proper operation. Document these safety checks.
  9. 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.
  10. 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.
