It recommends procedures and pract
30、ices which will result in safe and environmentally acceptable design, construction and operation of LNG plants. It need not be applied retrospectively, but application is recommended when major modifications of existing installations are being considered. 1 Scope This European Standard gives guideli
31、nes for the design, construction and operation of all onshore stationary liquefied natural gas (LNG) installations including those for the liquefaction, storage, vaporization, transfer and handling of LNG. Satellite plants with total storage capacity of less than 200 t are excluded from this Europea
32、n Standard. This European Standard is valid for the following plant types: export terminals, between the designated gas inlet boundary limit, and the ship manifold; receiving terminals, between the ship manifold and the designated gas outlet boundary limit; peak-shaving plants, between designated ga
33、s inlet and outlet boundary limits; LNG satellite plants with total storage capacity above 200 t, including the loading station up to the designated gas outlet boundary limit. A short description of each of these installations is given in annex G. 2 Normative references This European Standard incorp
34、orates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this Europ
35、ean Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.
