Purpose – Damage of oil and gas long‐distance transmission pipelines caused by corrosion, stresses, geological change …‐distance transmission pipelines on‐site overhaul, the robot developed in this paper utilizes a local magnetic flux leakage testing method …

reparation for long‐distance offshore oil pipelines. Design/methodology/approach – The autonomous in‐pipe robot performs online … oil pipelines. Originality/value – For the application of the autonomous in‐pipe robot, there are no special requirements … for maintained pipelines themselves, so it is applicable to the point reparation for most long‐distance welded offshore …

of industrial size pipelines. Nowadays, non‐destructive testing (NDT) methods are performed by dextrous technicians … and manipulating robot for inspection of industrial size pipelines. The robot is able to pass bends and T‐junctions. The V …
