Long-distance oil and gas pipelines are an important energy lifeline. In order to ensure the safety of pipelines, it is necessary to conduct inspections along the pipelines. The traditional inspection method is to rely on inspectors, but there are many disadvantages of inspection by inspectors. UAV inspection can be free of the constraints of terrain conditions, low cost, and high efficiency. Among them, the Vertical take-off and landing fixed wing UAV combines the characteristics of rotorcraft that can take off and land vertically and the long endurance of the fixed wing UAV. while hybrid VTOL UAV has outstanding achievability, reliable technology and low cost. It is more suitable for pipeline inspection operations and is one of the future development directions of pipeline protection.
