Abstract

Le dispositif de verrouillage est conçu pour pouvoir libérer sur commande l'extrémité d'une ligne de tension raccordée à une installation sous-marine, même en cas de défaillance des circuits de commande du déverrouillage. La ligne de tension 12 ou ombilicale est raccordée à l'installation 10 en 86 et 87 et se trouve verrouillée à 10 par la structure 24. L'effacement du verrou 67 est commandé par circuit hydraulique et en cas de défaillance par l'enfoncement d'une pièce 51 accessible par la fenêtre 90. L'invention s'applique principalement au raccordement d'installations sous-marines à grande profondeur.
