Abstract

Dispositif d'amortissement pour câble d'amarrage ancré au fond de la mer. Le dispositif comprend un récipient 16 muni d'un couvercle 5, et relié au dispositif d'ancrage 1 par une chaîne 22. Une plaque d'extrémité 8, mobile dans le récipient, est reliée à un flotteur 7 à travers le couvercle. Elle est poussée par un corps élastique intermédiaire 11, de forme tubulaire concentrique au câble. De préférence, ce corps de diamètre extérieur D et intérieur d et de hauteur H est tel que D/d = 1,8 à 2,2 et (D-d)/2/H = 0,15 à 0,25. Application courante.Damping device for a mooring cable anchored to the seabed. The device comprises a container 16 provided with a cover 5, and connected to the anchoring device 1 by a chain 22. An end plate 8, movable in the container, is connected to a float 7 through the cover. It is pushed by an intermediate elastic body 11, of tubular shape concentric with the cable. Preferably, this body of outside diameter D and inside d and of height H is such that D / d = 1.8 to 2.2 and (D-d) / 2 / H = 0.15 to 0.25. Current application.
