A pipe-laying vessel includes an upwardly extending tower (14) assembly defining a path down which the pipe passes as a pipeline (40) is being laid by the vessel, and a lower guide arrangement for guiding the pipeline after it has passed down the tower, the lower guide arrangement (61) including a plurality of sets of guide rollers spaced apart along the path of the pipeline and defining the lateral limits of the path, the guide rollers being located such that they allow some bending of the pipeline as it passes through the lower guide arrangement.
L'invention concerne un navire poseur de canalisations sous-marines comprenant un ensemble tour qui s'étend verticalement (14). Cet ensemble définit un trajet vers le bas le long duquel la canalisation descend comme pipeline (40) destiné à être posé par le navire. Le navire comprend aussi un arrangement de guidage inférieur (61) qui guide le pipeline, une fois celui-ci descendu le long de la tour, et qui comprend plusieurs séries de rouleaux de guidage espacés le long du trajet du pipeline et définissant les limites latérales du trajet. Les rouleaux de guidage sont placés de manière à permettre une certaine courbure du pipeline lorsque celui-ci passe par l'arrangement de guidage inférieur.
