Title
(EN) DEVICE FOR AND METHOD OF TENSIONING CHAINS, IN PARTICULAR MOORING LEGS
(FR) DISPOSITIF ET PROCÉDÉ DE TENSION DE CHAÎNES, EN PARTICULIER DES JAMBES D'AMARRAGE
Abstract
(EN) The invention relates to a device (1) for tensioning anchor chains, in particular mooring legs (2) of off-shore vessels (3) and installations, comprising a frame (5) carrying connectors (10, 11, 13) for holding together lower and upper portions (2B, 2A) of the chain (2) to be tensioned. The frame (5) further carries a tensioning mechanism (7) for pulling at least one portion of the chain (2A, 2B) towards the other portion of the chain (2A, 2B) while the device (1) is submerged.
(FR) L'invention porte sur un dispositif (1) pour tendre des chaînes d'ancre, en particulier des jambes d'amarrage (2) d'installations et de vaisseaux en mer (3), lequel dispositif comprend un bâti (5) portant des raccords (10, 11, 13) pour supporter ensemble des parties inférieure et supérieure (2B, 2A) de la chaîne (2) devant être tendue. Le bâti (5) porte de plus un mécanisme de tension (7) pour tirer au moins une partie de la chaîne (2A, 2B) vers l'autre partie de la chaîne (2A, 2B) lorsque le dispositif (1) est submergé.
