Abstract

Σύστημα για την προοδευτική απελευθέρωση εξ αποστάσεως μιας σειράς σφιγκτήρων συνεσφιγμένων διαδοχικά κατά μήκος μιας υποβρύχιας κατασκευής, το οποίο περιλαμβάνει ένα σχοινί απόσυρσης, το οποίο έχει μία ειδική διεύρυνση στο ένα άκρο και έιναι κατασκευασμένο για να διέρχεται δια μέσου των κεντρικών διαμπερών διατρήσεων στις συνδετικές περόνες, οι οποίες σφηνώνουν τους παρεμβαλλομένους στροφείς των σφιγκτήρων της σειράς, όπου οι εν λόγω περόνες είναι υπό την μορφή δύο συνδεόμενων μισών περόνων. Επίσης παρέχεται μία μέθοδος για την λειτουργία του συστήματος απελευθερώσεως. ωA system for the progressive release of a series of clamps sequentially clamped sequentially along an underwater structure, comprising a retraction rope having a special extension at one end and designed to pass through the central through holes in the connecting pins. which wedge the interlocking swivels of the series clamps, wherein said pins are in the form of two connected half pins. A method for operating the release system is also provided. ω
