Abstract:
A remotely operated device for inspecting and/or cleaning a subsea flexible pipe joint comprises a support assembly. In addition, the device comprises a tool positioning assembly coupled to the support assembly. The tool positioning assembly includes a rotating member disposed about a central axis. The tool positioning assembly is rotatable relative to the support assembly about the central axis. Further, the device comprises a cleaning assembly including a cleaning device adapted to clean the flexible pipe joint. The cleaning device is axially moveable relative to the rotating member. Still further, the device comprises a clamping assembly coupled to the support assembly. The clamping assembly has an open position disengaged with the section of the flexible pipe joint and a closed position engaging the section of the flexible pipe joint.
