38、tariat 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of an identical text or by endorsement, at the latest by November 2016, and conflicting national standards shall be withdrawn at the latest by November 2016. Attention is
39、drawn to the possibility that some of the elements of this document may be the subject of patent rights.

40、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 were subje

DIN EN 1473:2016-10EN 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 environmenta
44、lly 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 extension i
45、n 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 applic
46、ation 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 accurately de
47、fined with the local Authorities. DIN EN 1473:2016-10EN 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
48、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
49、 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, 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
