Abstract
As pipeline and energy storage infrastructure worldwide continues to age, viable assessment options for critical assets are becoming increasingly important to ensure the stable delivery of energy. Many assets are complex and require creative inspection solutions.
This paper discusses robotic inspection technologies for pipelines and storage tanks that are challenging to inspect with traditional methods. We will provide an overview of the following:
• A pipeline inspection project in South Korea using robotic Magnetic Flux Leakage (MFL) inspection technology. This unique MFL crawler technology can operate within a flowing gas environment, capable of crawling wirelessly into and out of a hot tap. The system has a full array of high-resolution MFL sensors, a live feed high-definition camera, and laser deformation detection.
• A multi-tank inspection program in the USA using robotic technology with ultrasonic (UT) sensors. This system can inspect a tank floor while the tank remains in service.
These projects and their unique challenges will be discussed to illustrate the importance of deploying the right technology for specific applications. We will also demonstrate that utilizing these systems reduced the overall engineering costs associated with traditional inspection technologies. Additionally, the benefits and values from understanding the integrity conditions of these critical elements of energy infrastructure will be shared to provide guidance on selecting appropriate inspection methods to acquire the breadth and quality of data that can assist operators in making informed decisions for their asset integrity programs. This ensures more reliable energy distribution, reduces environmental impact, and improves safety.
Operators should consider the type of inspection technology that will not only meet regulatory standards but provide all information required to contribute to a well-rounded asset integrity maintenance program. Inspection of those assets is key to ensuring that pre-emptive maintenance is possible, and the costs associated with adverse events avoided.
