Installation and equipment for liquefied natural gas - Design and testing of marine transfer systems - Part 1: Design and testing of transfer arms

This European Standard specifies the design, minimum safety requirements and inspection and testing procedures for liquefied natural gas (LNG) transfer arms intended for use on conventional onshore (LNG) terminals 1). It also covers the minimum requirements for safe LNG transfer between ship and shore. Although the requirements for remote control power systems are covered, the standard does not include all the details for the design and fabrication of standard parts and fittings associated with transfer arms. The content of this European Standard is supplementary to local or national standards and regulations and is additional to the requirements of EN 1532 and EN 1473.

Cette Norme Européenne spécifie les règles de conception, les prescriptions minimales de sécurité ainsi que
les procédures de contrôle et d'essais relatifs aux bras de chargement/déchargement de gaz naturel liquéfié
(GNL) destinés à être utilisés sur des terminaux terrestres conventionnels1). Elle fixe également les
prescriptions minimales permettant de garantir que le transfert de GNL entre le navire et le terminal s'effectue
en toute sécurité.
Bien que la présente norme s'applique aux systèmes de télécommande, elle ne fixe pas tous les détails
relatifs à la conception et à la fabrication des pièces normalisées et des raccords des bras de
chargement/déchargement.
Le contenu de cette Norme Européenne vient compléter les normes et règlements locaux ou nationaux, et
