30、he secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2016, and conflicting national standards shall be withdrawn at the latest by November 2016. Atten

31、tion is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1473:2007. In comparison with EN 1473:2007, the following chang

32、es have been made: the scope definition has been modified to cover interfaces and limits with floating solutions, plants refurbishing, renovation and expansion, and to better complement EN 14620; some requirements were revisited, such as tank containment types, new air vaporizer and sections that we

33、re subject to questions from the 2007 version; terms and definitions were adjusted to cope with new market development; the normative references were updated.

BS EN 1473:2016EN 1473:2016 (E) 8 Introduction The objective of this European Standard is to give functional guidelines for on-shore LNG installations. It recommends procedures and practices that will result in safe and environm

36、entally 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. This standard is also recommended for debottlenecking, revamping and plant life extensi

37、on in the limits that will be defined by the local Authorities. The appliance of the European Directives to the existing facilities is part of the limits to be defined together with the local Authorities. In case of plant expansion, this European Standard is applicable for the new facilities. The ap

38、plication of these recommendations for the tie-ins and connections to the existing facilities will be defined by the local Authorities. The limits of such application should consider the practicality of such appliance. In the same way the limits of the European Directives appliance will be accuratel

39、y defined with the local Authorities. BS EN 1473:2016EN 1473:2016 (E) 9 1 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

40、European Standard is valid for plants with LNG storage at pressure lower than 0,5 barg and capacity above 200 t and for the following plant types: LNG liquefaction installations (plant), between the designated gas inlet boundary limit, and the outlet boundary limit which is usually the ship manifold

41、 and/or truck delivery station when applicable; feed gas can be from gas field, associated gas from oil field, piped gas from transportation grid or from renewables; LNG regasification installations (plant), between the ship manifold and the designated gas outlet boundary limit; peak-shaving plants,

42、 between designated gas inlet and outlet boundary limits; the fixed part of LNG bunkering station. A short description of each of these installations is given in Annex G. Floating solutions (FPSO, FSRU, SRV), whether off-shore or nearby shore, are not covered by this European Standard even if some c

43、oncepts, principles or recommendations could be applied. However, in case of berthed FSRU with LNG transfer across the jetty, the following recommendations apply for the jetty and topside facilities if the jetty is located within 3 000 m from the shore line. In case of FSU type solution, the on-shor

44、e part is covered by these standard recommendations. This standard is not applicable for installations specifically referred or covered by other standards, e.g. LNG fuelling stations, LNG road or rail tankers and LNG bunkering vessels. The plants with a storage inventory from 50 t up to 200 t with t

45、anks at a pressure higher than 0,5 barg are covered by EN 13645. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
