ABSTRACT:
The invention provides a tool for disconnecting a guideline connector hooked in a sleeve forming the extension of a guide column of an underwater station, by means of retractable locking heads housed in a bore in the body of the connector.
It comprises a re-entry cone, whose upper cylindrical part 1, adapted to cap the top of the connector having helical ramps, comprises swivel pins to cooperate with said ramps and is connected to a widened cylindrical part 4, ending in an upturned funnel 5, by a truncated cone-shaped part 3, with which are associated valve means 18 for controlling hydraulic cylinders 14 and 14a responsive to the pressure exerted by the body of the connector, when the re-entry cone rests on the connector, as well as two hydraulic cylinders 14 and 14a and hydro-pneumatic accumulator 12, mounted outside the cone.
