Metals are traditionally used in Oil and Gas offshore applications as their short and long term performance is well documented, but they are approaching the limits of their capabilities, e.g. risers extending to the sea bed at great depths (giving rise to very high pipe collapse pressures) cannot support their own weight, hence thermoplastic composites are being investigated which (if used appropriately) can operate under these extreme conditions. Manufacturing parameters have great influence on the material properties, but non-destructive inspection is in its infancy for reliable quality control of components during manufacture. The goals of this project were to firstly design and build a prototype ultrasonic inspection module that could detect material defects during the filament winding manufacturing process of a composite pipe, and secondly to design and build a prototype repair module to repair the detected damage. Both goals were achieved, and the process will be described in the Lecture.
