SYSTEM AND METHOD FOR DETECTING THE WATERTIGHTNESS OF THE ANNULAR SPACE IN FLEXIBLE PIPES
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...

| description | 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. |
