Abstract: In order to meet the objectives described above, the present invention provides a robot for detecting breakdown of NORM (Naturally Occurring Radioactive Materials) in a production system, in order to plan operations to remove scale containing radioactive material, and for decommissioning subsea system operations. The fields of application are the area of flow assurance and reservoir management, using operations to chemically remove scale containing NORM in the production system, and to improve the safety of the decommissioning processes of production systems. The invention allows the position of the scale inside the production system to be safely detected, such as, for example, the beginning of the deposit inside a production line, the extension of the deposit, and the end of the deposit, as well as whether the deposit occurred at different points along the production line.
