CEN/TC 234/WG 7 - Gas compression

This document describes the specific functional requirements for the design, construction, operation, maintenance and disposal activities for safe and secure gas compressor stations.
This document applies to new gas compressor stations with a Maximum Operating Pressure (MOP) over 16 bar and with a total shaft power over 1 MW. For existing compressor stations, this document applies to new compressor units. Where changes/modifications to existing installations or gas composition take place, due account can be taken of the requirements of this document.
This document does not apply to gas compressor stations or compressor units operating prior to the publication of this document. For existing sites this document can be used as guidance.
The purpose of this document is to:
—   ensure the health and safety of the public and all site personnel;
—   cover environmental issues;
—   avoid incidental damage to nearby property; and
—   open the gas infrastructure to accommodate renewable gases, including a possible design for hydrogen.
This document specifies common basic principles for the gas infrastructure. Users of this document are expected to be aware that more detailed national standards and/or codes of practice can exist in the CEN member countries.
This document is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles.
In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this document, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts). CEN/TR 13737 (all parts) gives:
—   clarification of all legislations/regulations applicable in a member state;
—   if appropriate, more restrictive national requirements;
—   a national contact point for the latest information.
This document does not apply to:
—   off-shore gas compressor stations;
—   gas compressor stations for compressed gas filling-stations;
—   customer installations downstream of the point of custody transfer;
—   design and construction of driver packages (see Annex C);
—   mobile compressor equipment.
For supplies to utility services such as small central heating boilers reference is made to EN 1775.

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 Figure 1 shows a schematic representation of compressor stations in a gas supply system.
