Abstract

L'invention concerne un système de remplissage synchrone pour de multiples conteneurs-citernes de gaz naturel liquéfié (GNL), comprenant un tuyau collecteur (2), des tuyaux de branchement et des conteneurs-citernes de GNL (11). Le tuyau collecteur (2) est en communication avec une extrémité d'alimentation en liquide et une extrémité d'air de retour. Le tuyau collecteur (2) est également en communication avec une extrémité des multiples tuyaux de branchement ; l'autre extrémité de chaque tuyau de branchement est une extrémité de remplissage et chaque extrémité de remplissage est pourvue de manière correspondante d'un conteneur-citerne de GNL (11) au sein du même plan. Chaque conteneur-citerne de GNL (11) comporte sur celui-ci une extrémité de réception (15), et un dispositif d'amarrage automatique (3) est disposé entre les extrémités de remplissage des tuyaux de branchement et les extrémités de réception (15). L'invention concerne également un procédé de logistique pour transporter du GNL, comprenant : le remplissage synchrone de multiples conteneurs-citernes de GNL sur un navire de transport de citernes de GNL. L'invention concerne en outre un adaptateur de remplissage rapide à basse température, comprenant un adaptateur de remplissage mâle (81) et un adaptateur de remplissage femelle (82). L'adaptateur de remplissage mâle (81) comprend une colonne de guidage (811) et un premier mécanisme d'étanchéité (83) destiné à réaliser l'étanchéité de la colonne de guidage (811). L'adaptateur de remplissage femelle (82) comprend une colonne de transport d'écoulement (821) utilisée par la colonne de guidage (811) l'insertion avec ajustement et un deuxième mécanisme d'étanchéité (84) utilisé pour réaliser l'étanchéité de la colonne de transport d'écoulement (821). La colonne de guidage (811) et la colonne de transport d'écoulement (821) contiennent respectivement une première chambre à vide (812) et une deuxièmes chambre à vide (822) le long de leur direction longitudinale.
