Industries du pétrole et du gaz naturel — Conception et essais des bras de transfert de GNL sur des terminaux terrestres conventionnels
L'ISO 16904:2016 spécifie les règles de conception, les spécifications minimales de sécurité ainsi que les procédures de contrôle et d'essais relatifs aux bras de transfert de gaz naturel liquéfié (GNL) marins destinés à être utilisés sur des terminaux terrestres conventionnels, recevant des méthaniers engagés dans le commerce international. Elle peut fournir des lignes directrices pour des opérations côtières et au large. Elle fixe également les spécifications minimales permettant de garantir que le transfert de GNL entre le navire et le terminal s'effectue en toute sécurité. Bien que les spécifications relatives aux systèmes d'alimentation/télécommande soient couvertes, l'ISO 16904:2016 ne fixe pas tous les détails relatifs à la conception et à la fabrication des pièces normalisées et des raccords des bras de transfert.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes
nationaux de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est
en général confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude
a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec l’ISO participent également aux travaux.
L’ISO collabore étroitement avec la Commission électrotechnique internationale (IEC) en ce qui
concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1 Il convient, en particulier, de prendre note des différents
critères d’approbation requis pour les différents types de documents ISO. Le présent document a été
rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2 (voir www.

NORME INTERNATIONALE ISO 16904:2016(F)
Industries du pétrole et du gaz naturel — Conception et
essais des bras de transfert de GNL sur des terminaux
terrestres conventionnels
1 Domaine d’application
La présente Norme internationale spécifie les règles de conception, les spécifications minimales de
sécurité ainsi que les procédures de contrôle et d’essais relatifs aux bras de transfert de gaz naturel
liquéfié (GNL) marins destinés à être utilisés sur des terminaux terrestres conventionnels, recevant des
méthaniers engagés dans le commerce international. Elle peut fournir des lignes directrices pour des
opérations côtières et au large. Elle fixe également les spécifications minimales permettant de garantir
que le transfert de GNL entre le navire et le terminal s’effectue en toute sécurité.
Bien que les spécifications relatives aux systèmes d’alimentation/télécommande soient couvertes, la
présente Norme internationale ne fixe pas tous les détails relatifs à la conception et à la fabrication des
pièces normalisées et des raccords des bras de transfert.
La présente Norme internationale vient compléter les normes et règlements locaux ou nationaux, et
s’ajoute aux spécifications de l’ISO 28460.
Il n’est pas nécessaire d’appliquer la présente Norme internationale aux installations existantes.
