Abstract: A system for detecting the watertightness or flooding of an annulus of flexible lines from a connector. The system includes: an assembly of plunger and cylinder that are connected by a rod to a chamber that acts as a pilot valve. The assembly is connected directly to the outlet of a safety valve of a connector of the flexible line, in which same are fitted using a sealing system. The system is operated by commands sent to a ROV that has an arm and that controls the system using a handle.

Abstract: This invention provides a system for detecting flooding in a flexible pipe from a connector of the flexible pipe, comprising: an ROV (3) comprising an arm element (18) designed to move an ultrasound sensor (13), until the ultrasound sensor (13) comes into contact with the connector (14) of the flexible pipe (17); and means for taking ultrasound measurements with respect to the state of the annulus of the flexible pipe (17) from a chamber of the connector of the flexible pipe (17) in contact with the annulus of the flexible pipe (17).

Abstract: The present invention relates to a system for detecting the watertightness or flooding of the annulus of flexible lines from a connector, comprising: an assembly of plunger (3) and cylinder (4) that are connected by a rod to a chamber (19) that acts as a pilot valve, connected directly to the outlet of a safety valve of a connector of the flexible line, in which same are fitted using a sealing system (6). The system is operated by commands sent to the ROV (2) that has an arm (21) and that controls the system using a handle (9). The present invention also describes the operating method of the device and how the obtained results lead to a preprogrammed conclusion regarding the watertightness (or otherwise) of the annulus. Other methods are provided to obtain fluid samples in the annulus for subsequent analysis and enable the safety valve to be removed from the connectors.
