This standard specifies procedures and practices which are safe and environmentally acceptable.
It covers the functional recommendations for design, construction, testing, commissioning, operation and maintenance of underground gas storage facilities in oil and gas fields up to and including the wing valve of the wellhead.
The necessary surface facilities for underground gas storage are described in EN 1918-5. In this context "gas" is any gaseous fuel which is in a gaseous state at a temperature of 15 ℃ and under a pressure of 1 bar and which remains in a gaseous state under storage conditions.
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 these national standards and/or codes of practice and does not replace them.
This standard is not intended to be applied retrospectively to existing facilities.
