A flexible joint for conveying a fluid in a fluid pipe in order to unite two pipes in leaktight and flexible manner comprises a tubular vessel having an upstream end for flexible and leaktight connection with an upstream tube, a downstream end for leaktight connection with a downstream tube, and a tubular bellows fastened in leaktight manner to the inside of the vessel, thereby defining two concentric spaces that are mutually separated in leaktight manner in normal operation. An inner space is provided in which the fluid flows between the upstream end and the downstream end. A peripheral space is situated between the inner space and a side wall of the vessel and is filled with an incompressible liquid. The joint further includes at least one sensor for detecting a hydrocarbon fluid in the incompressible liquid if the seal is broken between the inner space and the peripheral space.

Flexible joint for hydrocarbon pipes, a method of detecting a leak in such a joint, and a system for detecting a hydrocarbon leak in such a joint

The invention relates to an undersea connector for connecting an oil installation to the sea bottom, the connector being of the type presenting a first tubular element forming a female portion for fastening to the ocean bottom and a second tubular element forming a male portion for connection to the oil installation, wherein the connector comprises at least one anti-disconnection device for the connector, the device being housed in the female portion and comprising means for positioning the device in a first position in which the connector is capable of being disconnected, or else in a second position in which the connector cannot be disconnected.
