Abstract: Apparatus for condition control of a pipeline with a fluid flow pipe for transport of a fluid, comprising a plurality of ultrasonic transducers arranged in the vicinity of the external surface of the pipeline. By emitting, receiving and analyzing ultrasonic signals by means of ultrasonic transducers it is possible to perform a characterization of the pipeline, for example a measurement of the pipeline wall thickness. Ultrasonic transducers are arranged as an integral part of at least one tape.

Abstract: An x-ray radiography tomography device for a flexible riser, particularly a riser end fitting on a riser hangoff block on a petroleum platform, the x-ray radiography device comprising the following features:

Abstract: A system for inspecting pipelines, especially in the coupling between pipe parts, comprises a radiation source and a detector device or a photographic film. The pipeline includes indicators which are laid into the pipeline material and have a differing absorption of radiation than the material comprising the layers of the pipeline in which the indicators are formed. By placing the radiation source and the detector device (or photographic film) on opposite sides of the pipeline, or on opposite sides of a wall of the pipeline, the position of the indicators may be detected, and any displacement can be measured.
