Around 40-50 % of all oil and gas pipelines around the world is non-piggable for one reason or another. There is growing tendency in the market to look into the integrity of these pipelines.

Pipesurvey International has developed a tool that can cover at least a bulk part of these pipelines. The XHR MFL tool incorporates all features of any up-to-date MFL ILI tool. The surplus value of the tool is that it is of complete bidirectional design, multidimensional and it has short bend-radius capability. The tool can be launched into a single-entry pipeline, be retrieved back at the same point and in the mean time inspect any length of pipeline. The tool is autonomous but can be operated with an umbilical as well. It is possible to combine the tool with a self propelling pipe robot, which takes the inspection range even one step further.
