Abstract

L'invention porte sur des agencements d'accouplement d'au moins un tuyau souple acheminant un fluide, en particulier du gaz naturel liquéfié et/ou du gaz naturel liquéfié vaporisé. Une extrémité de tuyau souple (63) du ou des tuyaux souples a un raccord (91) d'extrémité de tuyau souple destiné à être relié à un ensemble de réception (90) sur une première structure (80) située dans l'eau. Le raccord (91) d'extrémité de tuyau souple comporte des moyens de guidage (102), et l'ensemble de réception (90) comporte des moyens de réception (71). L'agencement comprend des moyens de manoeuvre pour manoeuvrer le raccord (91) d'extrémité de tuyau souple de façon à placer les moyens de guidage (102) dans les moyens de réception (71) et à loger les moyens de guidage (102) dans les moyens de réception (71) de telle sorte que les moyens de guidage (102) soient maintenus dans les moyens de réception (71) et que le poids du raccord (91) d'extrémité de tuyau souple soit transféré aux moyens de réception (71). Le raccord (91) d'extrémité de tuyau souple a une position de liaison avec un accouplement de tuyau de réception (15) dans l'ensemble de réception (90), un accouplement de tuyau de réception (15) étant prévu pour chaque raccord (91) d'extrémité de tuyau souple. L'invention porte également sur des procédés d'accouplement et de désaccouplement d'au moins un tuyau souple acheminant un fluide, en particulier du gaz naturel liquéfié et/ou du gaz naturel liquéfié vaporisé.
