A chain connector for holding a chain (14) that moors a vessel to the sea floor under perhaps 2000 tons tension, which can be quickly disconnected in an emergency by applying a moderate disconnecting force such as 50 tons. The chain is held by ratchets (24, 26) that are mounted on arms (34, 36). The arms have upper ends (35) that are pivotally mounted on a housing (38) and have free lower ends (44), with the lower ends being held by cams (50) on locking dogs (52) that have locking dog lower ends (51) pivotally mounted on the housing and free upper ends (60). A hydraulic actuator (70) has pins (58) that engage the upper ends of the locking dogs to prevent the arms and dogs from pivoting apart until the locking dog upper ends (60) are raised.
Connecteur de chaîne servant à maintenir une chaîne (14) pouvant amarrer un vaisseau jusqu'au fond de la mer sous éventuellement 2 000 tonnes de tension, qui peut être rapidement déconnecté en cas d'urgence par l'application d'une force de déconnexion modérée, par exemple 50 tonnes. La chaîne est maintenue par des rochets (24, 26) qui sont montés sur des bras (34, 36). Les bras ont des extrémités supérieures (35) qui sont montées de manière pivotante sur un logement (38) et ont des extrémités inférieures libres (44), maintenues par des cames (50) sur des griffes de blocage (52) dont les extrémités inférieures (51) sont montées de manière pivotante sur le logement et dont les extrémités supérieures (60) sont libres. Un actionneur hydraulique (70) possède des axes (58) qui viennent en prise avec les extrémités supérieures des griffes de verrouillage pour empêcher l'écart de pivotement entre les bras et les griffes jusqu'à ce que les extrémités supérieures de la griffe de blocage (60) soient levées.
