CA 2346565

The invention concerns an assembly for constructing an underwater system for transporting fluid, energy or signals, comprising at least two installation conduits (1) connected by a connecting device (11), and a traction device (21) for pulling on the conduit(s) (1). The invention is characterised in that each conduit (1) comprises an inner sheath (2) enclosed in a sealing layer forming a peripheral ballast and optionally an outer sheath (10), said traction device including two elements set in place by being screwed on the conduit end (1) so as to enclose tightly said conduit (1) wall over its entire periphery, and the connecting device(s) (11) consisting in a single sleeve-type part (13), which has two opposite end fittings (14a, 14b) whereon are directly mounted sealing means such as ring type joints (33) and which are capable of being screwed on each of the internal sheaths (2).

Cet ensemble pour la construction d'un réseau de transport subaquatique de fluide, d'énergie, ou de signaux, comportant au moins deux conduits (1) d'installation raccordés à l'aide d'un dispositif de connexion (11), et un dispositif de traction (21) pour tirer sur le(s) conduit(s) (1). Selon l'invention, chaque conduit (1) comprenant une gaine intérieure (2) entourée d'une couche d'étanchéité formant lest périphérique et éventuellement une gaine extérieure (10), le dispositif de traction comportant deux éléments mis en place par vissage sur l'extrémité du conduit (1) de manière à enserrer la paroi dudit conduit (1) sur toute sa périphérie, et le ou les dispositifs de connexion (11) étant réalisés en une seule pièce du type manchon (13), lequel présente deux embouts (14a, 14b) opposés sur lesquels sont rapportés des moyens d'étanchéité du type joints toriques (33) et lesquels sont aptes à être vissés sur chacune des gaines intérieures (2).
