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). The invention further provides a method for detecting flooding in a flexible pipe from a connector of the flexible pipe, comprising the steps of: moving an ROV (3) to a region close to the connector (14) of the flexible pipe (17); activating an arm element (18) of the ROV (3) to move an ultrasound sensor (13), until the ultrasound sensor (13) comes into contact with the connector (14) of the flexible pipe (18); and taking ultrasound measurements with respect to the state of the annulus of the flexible pipe (17) from a chamber of the connector (14) of the flexible pipe (17) in contact with the annulus of the flexible pipe (17).

Methods and systems are provided for a power-generating fluid flow arrangement. In one example, the fluid flow arrangement may include a primary conduit flowing a pressurized fluid and a bypass conduit coupled to the primary conduit. The bypass conduit may divert a portion of the pressurized fluid flow from the primary conduit to drive rotation of a turbine. A dual valve may be arranged in the bypass conduit to control both flow and pressure in the fluid flow arrangement.

A system and method for detecting dynamic strain of a housing. The system includes an optical fiber linearly affixed along a surface of a length of the housing and an interrogator comprising a laser source and a photodetector. The optical fiber comprises at least one pair of fiber Bragg gratings (FBGs) tuned to reflect substantially identical wavelengths with a segment of the optical fiber extending between the FBGs. The segment of the optical fiber is linearly affixed along the surface of the housing. The interrogator is configured to perform interferometry by shining laser light along the optical fiber and detecting light reflected by the FBGs. The interrogator outputs dynamic strain measurements based on interferometry performed on the reflected light.
