Title (EN) REEL MOUNTABLE BOOM ARRANGEMENT
(FR) DISPOSITIF DE CHAINE DE FERMETURE POUVANT ETRE MONTE SUR UNE BOBINE
Abstract: front page image
(EN)An improved containment barrier or boom (10) having a flotation (12) and a skirt section dependent (14) therefrom. The boom (10) may be wound around a reel (60) for storage, and deployed from the reel (60) as required. The flotation (12) comprises a flexible, longitudinally elongated tubular member (34), having a cavity (38) extending throughout the elongated length thereof. A resilient, generally springlike member (40) having helical coils (42) is provided in the tubular member (34). The spring-like member (40) extends substantially longitudinally throughout the length of the tubular member (34), and the helical coils (42) maintain the walls of the tubular member (34) in a transversely expanded condition when the tubular member (34) is deployed in the body of water. The spring-like member (40) is resiliently deformable from the helical condition to a transversely flattened condition, when the tubular member (34) is wound upon the reel (60) for storage. The spring-like member (40), when in the transversely flattened storage condition thereof, has sufficient energy stored therein so that, upon deployment or unwinding from the reel (60), the spring-like member (40) will move from its transversely flattened storage condition to its helical condition, thereby expanding the tubular member (34) to its deployed condition.
(FR)Barriere de retenue ou chaine de fermeture amelioree (10) ayant une gaine de flottaison (12) et une jupe (14) dependant de celle-ci. La chaine de fermeture (10) peut etre enroulee autour d'une bobine (60) a des fins de stockage, et deployee de la bobine (60) si necessaire. La flottaison (12) comprend un organe tubulaire flexible allonge (34) ayant une cavite (38) s'etendant sur toute sa longueur. Un organe elastique en forme de ressort (40) ayant des spires helicoidales (42) est adapte dans l'organe tubulaire (34). L'organe en forme de ressort (40) s'etend sensiblement longitudinalement sur toute la longueur de l'organe tubulaire (34), et les spires helicoidales (42) maintiennent les parois de l'organe tubulaire (34) etendues transversalement lorsque l'organe tubulaire (34) est deploye dans le plan d'eau. L'organe en forme de ressort (40) est elastiquement deformable d'un etat helicoidal en un etat aplati transversalement, lorsque l'organe tubulaire (34) est enroule sur la bobine (60) pour son stockage. L'organe en forme de ressort (40), lorsqu'il se trouve dans son etat de stockage aplati transversalement, possede une energie emmagasinee suffisante pour que, lors de son deploiement ou deroulement de la bobine (60), l'organe en forme de ressort (40) se deplace de son etat de stockage aplati transversalement vers son etat helicoidal, etirant ainsi l'organe tubulaire (34) vers son etat deploye.
