DEVICE FOR ACCESSING THE ANNULAR SPACING OF SUBSEMINATE FLEXIBLE PIPES THROUGH DISCHARGE VALVES

Abstract

DEVICE FOR ACCESSING THE ANNULAR SPACE OF SUBSEMINATE FLEXIBLE CONDUITS THROUGH RELIEF VALVES The present invention discloses a device (100) for accessing the annular space of submarine flexible conduits through relief valves (12), which includes locking means for securing the device (100) to a housing (13) of the relief valve (12) after actuation, means for hermetically sealing an isolation chamber (2) of the device (100) against an internal surface (E) of the relief valve (12) after actuation, and compensation means (10). The compensation means (10) are arranged to cause the locking means to act before the sealing means.
