Abstract

Energy pipelines require regular inspection and health monitoring against defects, cracks, and corro- sion due to the fluid pipe interaction and external en- vironment conditions. Accurate and efficient pipeline inspection is extremely important to the oil and gas in- dustry. Inspection of pipelines is usually carried out either internally using smart pigs and tethered robots or externally with limited inspection options. Internal inspection has many limitations and external inspection is still primitive. However, external inspection has the advantage of being carried out without interruption of the production process. In this paper, a novel design for an autonomous robot for pipeline external inspection is presented. Although, the proposed design is developed mainly to fit a magnetic flux leakage based inspection technique, the robot modular design will fit other in- spection methods and applications withminimal design modifications. The proposed robot is designed to carry multiple hall effect sensors and allow adjustment of the radial distance between the sensors and the pipe sur- face. Also, the robot is able to scan different size pipes and maintain constant distance from the pipe surface. A prototype is fabricated using 3D printer and standard fasteners to evaluate the workability of the proposed design. The initial testing of the developed prototype showed that the robot can be made to move at a con- stant speed without slipping. The design details and the prototype elements are delineated in this paper.
