This European standard describes the specific functional requirements for the design, construction, operation, maintenance and disposal activities for safe and secure gas compressor stations.
This European standard applies to gas compressor stations with a Maximum Operating Pressure (MOP) over 16 bar and with a total shaft power over 1 MW.
This European standard need not be applied to gas compressor stations operating prior to the publication of this standard.
For gas compressor stations already in service, this standard applies by analogy only to the parts of the stations to be modified, extended or disposed. This standard can also be applied at any time to areas of operation and maintenance.
The purpose of this European standard is to ensure the safety of the public and the safety of all the personnel involved, to cover environmental issues and avoid damage to property.
This European Standard specifies common basic principles for gas supply systems. Users of this European Standard should be aware that more detailed national standards and/or codes of practice may exist in the CEN member countries.
This European Standard is intended to be applied in association with the national standards and/or codes of practice setting out the above mentioned principles.
In the event of conflicts in terms of more restrictive requirements in the national legislation/regulation with the requirements of this standard, the national legislation/regulation shall take precedence.
This standard does not apply to :
- off-shore gas compressor stations;
- gas compressor stations for compressed natural gas filling-stations
