Installation and equipment for liquefied natural gas - Design of onshore installations
This document 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 and natural gas (NG).
This document is applicable for plants with an LNG storage capacity above 200 t.
The designated boundary limits are LNG inlet/outlet by the ship’s manifold including vapour return connection, the truck loading/unloading connection including vapour return, the rail car loading/unloading connection including vapour return and the natural gas in and outlet boundary by piping systems.
Terminals or plant types have one or more boundary limits as described in this scope (see Figure 1).
A short description of each of these installations is given in Annex G.
Feed gas for LNG liquefaction installations (plant) can be from gas field, associated gas from oil field, piped gas from transportation grid or from renewables.
Floating solutions (for example FPSO, FSRU, SRV), whether off-shore or near-shore, are not covered by this document even if some concepts, 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.
In case of solutions using floating storage unit (FSU) and land-based re-gasification solution, the on-shore part is covered by these standard recommendations.
Plants with a storage inventory from 5 t up to 200 t are covered by [5].
Anlagen und Ausrüstung für Flüssigerdgas - Auslegung von landseitigen Anlagen
Dieses Dokument gibt Leitlinien für die Planung, den Bau und den Betrieb von allen landseitigen Flüssigerdgasanlagen für die Verflüssigung von Erdgas sowie für die Lagerung, die Verdampfung, die Weiterleitung und den Umgang mit LNG und Erdgas (NG, en: natural gas).
Dieses Dokument ist anzuwenden für Anlagen mit einer LNG-Lagerkapazität von mehr als 200 t.
Die vorgesehenen Anlagengrenzen sind der LNG Ein- und Austritt durch die Schiffsübergabestelle einschließlich Dampfrücklaufanschluss, der Anschluss für die Be- und Entladung von Tankwagen einschließlich Dampfrückführung, der Anschluss für die Be- und Entladung von Schienenfahrzeugen einschließlich Dampfrückführung und die Ein- und Austrittsgrenze von Erdgas durch Rohrleitungssysteme.
Anlandeterminals oder Anlagentypen haben eine oder mehrere Abgrenzungen, wie in diesem Anwendungsbereich beschrieben (siehe Bild 1).
[Bild 1]
Eine kurze Beschreibung jeder dieser Anlagen ist in Anhang G enthalten.
Einspeisegas für LNG-Verflüssigungsanlagen kann aus einem Erdgasfeld, Erdölbegleitgas aus einer Erdöllagerstätte, Pipelinegas aus einem Gasleitungsnetz oder aus erneuerbaren Quellen sein.
Schwimmende Lösungen (z. B. FPSO, FSRU, SRV), ob auf See oder in Küstennähe, werden in diesem Dokument nicht behandelt, auch wenn einige Begriffe, Grundsätze oder Empfehlungen auf sie angewendet werden könnten. Bei fest vertäuten LNG-Wiederverdampfungsanlagen (FSRU) mit LNG-Transfer über einen Schiffsanleger gelten die nachfolgenden Empfehlungen für den Schiffsanleger (inklusive der Einrichtungen auf dem Schiffsanleger).
Bei Lösungen in Form von schwimmenden Lagern (FSU) und Wiederverdampfung an Land wird der landseitige Teil durch die Empfehlungen dieser Norm abgedeckt.
Anlagen mit einem Lagerbestand von 5 t bis zu 200 t werden in [5] behandelt.
Installation et équipements de gaz naturel liquéfié - Conception des installation terrestres
Le présent document donne des lignes directrices relatives à la conception, à la construction et au fonctionnement de toutes les installations terrestres de gaz naturel liquéfié (GNL) destinées à la liquéfaction, au stockage, à la vaporisation, au transfert et à la manipulation du GNL et du gaz naturel (GN).
Le présent document est valable pour les installations comportant un stockage de GNL d’une capacité supérieure à 200 t.
Les limites de propriété prévues correspondent à l’entrée/la sortie du GNL à la bride du navire incluant la connexionde retour gaz, les connexions de chargement/déchargement des camions incluant le retour gaz, la connexion de chargement/déchargement des trains incluant le retour gaz, ainsi que les limites de propriété en entrée et sortie du gaz naturel par les réseaux de tuyauterie.
Les différents types de terminaux ou d’installations possèdent une ou plusieurs limites de propriété, comme indiqué dans le présent domaine d’application (voir Figure 1).
Une description succincte de ces différentes installations est donnée dans l’Annexe G.
Le gaz alimentant les terminaux de liquéfaction de GNL (installation) peut être du gaz de champ, du gaz associé à un champ de pétrole, du gaz de canalisation provenant du réseau de transport ou de sources d’énergie renouvelables.
Les solutions flottantes (FPSO, FSRU, SRV), qu’elles soient off-shore ou à proximité du rivage, ne sont pas couvertes par ce document, même si certains concepts, principes ou recommandations pourraient être appliquées. Toutefois, en cas de FSRU amarré avec transfert de GNL à travers la jetée, les recommandations suivantes s’appliquent pour la jetée et les installations de superstructures.
En cas de solution de type unité de stockage flottante (FSU) et de solution terrestre de re-gazification, la partie sur la rive est couverte par les présentes recommandations normalisées.
Les installations d’une capacité de stockage comprise entre 5 t et 200 t sont couvertes par [35].

Introduction
The objective of this document is to give functional guidelines for on-shore LNG installations. It
recommends procedures and practices that will result in safe and environmentally acceptable design,
construction and operation of LNG plants.
Given the wide range of facilities from small to large, with high and low risk profile, etc., the
acceptability criteria could vary depending on the project and are subject to conclusions by the
normative risk assessment.
Seveso, PED, and ATEX Directives are expected to be followed. Where national and/or local regulations
exist in which some of the requirements are equal or more stringent than in this document, it is up to
agreement with national and/or local regulators to determine which of the requirements apply.
It does not need to be applied retrospectively, but application is recommended when major
modifications of existing installations are being considered.
This document is also recommended for debottlenecking, revamping and
