Beschreibung
Zusammenfassung:	A pressure-actuated release mechanism is assembled using a prebuckled pipe segment as a pressure-triggering mechanism. The trigger mechanism is employed to attach buoys to an offshore structure or pipeline under construction. The attached buoys move with the structure or newly added pipe string toward the sea bottom, easing the descent. As a preselected external pressure is sensed, the buckle in the pipe segment propagates and the trigger mechanism actuates, releasing buoys from the structure or pipeline as each buoy in turn reaches the same depth or pressure.
