Essentials of CNG Station Operation and Maintenance

CNG fueling stations are complex systems. Because CNG stations provide extremely high-pressure fuel, NFPA 52, the primary CNG fueling station design, operation and maintenance code, requires a written maintenance plan for every existing and new station. Station owners, maintenance technicians and third-party providers must understand and implement required maintenance practices to ensure the safety of everyone who enters the station. In addition, they must be able to ensure station reliability and protect the financial investment.

Essentials of CNG Station Operation and Maintenance is a two-day course that teaches owners, managers, third-party providers and maintenance technicians the maintenance requirements and practices for each component. It teaches how to develop and implement the required maintenance plan, and how to meet all regulatory requirements. It also covers the practical how-to’s of preventive maintenance, diagnostics and troubleshooting, record keeping, conducting a safety evaluation and more.

For CNG fueling stations owners, operators and third-party maintenance contractors, this Essentials course provides the knowledge necessary to design and implement a successful maintenance plan that ensures the highest level of equipment and system reliability and fuel quality required by today’s NGV operators.
