EVS-EN 13645:2002

This European Standard specifies requirements for the design and construction of onshore stationary liquefied
natural gas (LNG) installations with a total storage capacity between 5 t and 200 t. This standard is not applicable
to liquefaction process facilities based on hydrocarbon refrigerants. Larger installations are treated according to
EN 1473:1997.
If other dangerous substances are present in the facility, the aforementioned storage capacity thresholds may be
reduced.
NOTE It is essential that the designer refer to local regulation to determine the new values.
The installations to which this standard is applicable include the following:

LNG satellite plants. The LNG may be supplied by road tankers, barge or rail carriers. After storage, LNG is
vaporized and sent out to consumers;

LNG gas fuelling stations for vehicles.
The installation is limited from the gas inlet or the loading LNG area to the gas outlet or the unloading LNG area.
Filling systems are not covered here.
For the purposes of clause 4 «Environment Impact» and clause 5 «Safety Plan», this standard applies where LNG
storage capacity exceeds the threshold specified in the local regulation. If this value is not available, a threshold of
50 t is recommended.
It is recalled that, in any case, local regulations prevail.
