Abstract

A system for the progressive remote release of a series of clamps clamped in succession along an underwater structure, comprising a withdrawal rope which has a special enlargement at one end and is made to pass through the central through bores in the connection pins which lock the Insertion hinges of said clamps of the series, said pins being in the form of two coupled half-pins. A method for operating the release system is also provided. [CA1337580C]
