The present intervention systems, for solving pipeline blockage or leak problems, are reaching their limits. New realities demand new technology for unusual interventions. In looking for better solutions, it was necessary to bypass the traditional methods used by the oil industry in order to investigate the inner surface of the pipeline. This work describes the development of a remote controlled apparatus, which is flow rate independent. This device could move freely inside the pipelines. A robot and its remote control operation system are the important factors, which would response to these new demands. The robot could be designed with special features such as the introduction of a specific solvent to dissolve or break the blockage; it could also be used as a tool-carrier. The system is able to drive accurately to the problem point, and use the adequate device to inspect and even to repair the inner surface structure of the pipeline.
