Loading and unloading of liquefied natural gas (LNG) tank wagons and containers (ISO 5124:2024)
This document provides the design and operational requirements for transportation of LNG as cargo by railcar, including safety aspects under normal conditions and in case of events.
This document includes requirements for (at least):
- railcar coupling;
- hose vs loading arm;
- hose / arm draining;
- permissives and emergency shut-down functions;
- liquid detection on boil-off gas return line;
- leak / fire detection and management systems.
LNG-Kesselwagen/Container Be- und Entladen (ISO 5124:2024)
Diese Internationale Norm umfasst Richtlinien und Empfehlungen für die Bauweise, die Konstruktion und den Betrieb von neu installierten Bahnbeladezonen/Bahnentladezonen für Flüssigerdgas (LNG) für die Nutzung an landseitigen LNG-Verladestationen, LNG-Satellitenanlagen, die Handhabung von LNG-Kesselwagen oder von Tankcontainern, die in (inter)nationalem Handel eingesetzt werden.
Diese Internationale Norm gilt ergänzend zu lokalen oder nationalen Normen und Vorschriften.
Die festgelegten Grenzen dieser Norm liegen zwischen den Verteilerrohren der Einlass-/Auslassrohrleitungen der LNG-Verladestationen am Anfang der Bahnbeladezone/Bahnentladezone und dem Gleisbereich, der für Kesselwagen/Tankcontainer genutzt wird. Dazu gehören alle Bahnverladezonen, Brückenwagen und alle dazu gehörigen Untersysteme.
Chargement et déchargement de wagons-citernes et conteneurs de gaz naturel liquéfié (GNL) (ISO 5124:2024)
La présente Norme internationale contient des lignes directrices et des recommandations pour la conception, la construction et l’exploitation de nouvelles installations ferroviaires de chargement et de déchargement de gaz naturel liquéfié (GNL) destinées à être utilisées sur des terminaux méthaniers terrestres, des stations satellites de GNL, pour la manutention de wagons ou de conteneurs-citernes de GNL dans le cadre du commerce international.
Les limites désignées pour la présente norme se situent entre les collecteurs d’entrée/de sortie du terminal méthanier au début de la zone de (dé)chargement ferroviaire et la zone de la voie ferrée utilisée pour les wagons-citernes et conteneurs de GNL. Elle comprend tous les quais de chargement ferroviaires, le ou les ponts bascules et les sous-systèmes connexes.
