Abstract

Flotteur formé d'un tube continu séparé en compartiments. A chaque compartiment aboutit l'extrémité d'une canalisation résistant à la pression reliée par son autre extrémité à un poste de mise sous pression situé en surface Les canalisations sont fixées dans le tube flotteur et traversent de manière étanche les cloisons. Un clapet anti-retour permet la décompression des compartiments lors de leur remontée. Application à la pose de conduites sous-marines.
