G 495 (A)
Gas plants and systems - Operation and maintenance
Gasanlagen - Betrieb und Instandhaltung
Brief description
This worksheet was developed by the Gas Systems - Operation and Maintenance project group in the Technical Committee for Systems Engineering. It serves as a basis for the operation and maintenance of gas systems. Maintenance is of central importance for ensuring the availability and operational safety of gas systems. The simultaneous requirement to consider maintenance from an economic point of view in particular means that the field of maintenance in particular continues to develop in a constant optimization process. Since the introduction of condition-based maintenance with the July 2006 edition of DVGW Code of Practice G 495, companies now have experience that proves the successful application of this maintenance strategy. Further considerations and findings from operational experience have led to it now being accepted. Condition-based maintenance still places increased demands on the qualifications of the operating personnel and the long-term documentation of the system condition and the associated operating parameters, but offers the opportunity to further exploit the existing utilization potential without reducing the safety, reliability and availability of the system. The special requirements for the introduction and application of condition-based maintenance have already been pointed out and described in detail in the 2006 edition. With the publication of this edition of DVGW Code of Practice G 495, further information on practical implementation is provided and the application of condition-based maintenance is consistently deepened and expanded. The Code of Practice thus makes a significant contribution to the long-term, safe, reliable, efficient and environmentally friendly supply of energy. This worksheet replaces DVGW worksheet G 495, July 2006 edition.
