scope:

This European Standard gives guidelines for the design,construction and operation of all onshore liquefied natural gas(LNG) installations for the liquefaction, storage, vaporization,transfer and handling of LNG. This European Standard is valid forplants with LNG storage at pressure lower than 0,5 barg andcapacity above 200 t and for the following plant types: - LNGliquefaction installations (plant), between the designated gasinlet boundary limit, and the outlet boundary limit which isusually the ship manifold and/or truck delivery station whenapplicable; feed gas can be from gas field, associated gas from oilfield, piped gas from transportation grid or from renewables; - LNGregasification installations (plant), between the ship manifold andthe designated gas outlet boundary limit; - peak-shaving plants,between designated gas inlet and outlet boundary limits; - thefixed part of LNG bunkering station. A short description of each ofthese installations is given in Annex G. Floating solutions (FPSO,FSRU, SRV), whether off-shore or nearby shore, are not covered bythis European Standard even if some concepts, principles orrecommendations could be applied. However, in case of berthed FSRUwith LNG transfer across the jetty, the following recommendationsapply for the jetty and topside facilities if the jetty is locatedwithin 3000 m from the shore line. In case of FSU type solution,the on-shore part is covered by these standard recommendations.This standard is not applicable for installations specificallyreferred or covered by other standards, e. g. LNG fuellingstations, LNG road or rail tankers and LNG bunkering vessels. Theplants with a storage inventory from 50 t up to 200 t with tanks ata pressure higher than 0,5 barg are covered by EN 13645.
