Design improvements, field tests, and design for manufacturability analysis will advance system for trenchless inspection of cased natural gas transmission lines via vent access
NYSEARCH/Northeast Gas Association (NGA) and Honeybee Robotics are developing and testing a new generation of a pipe inspection robot for cased natural gas transmission lines. This robotic system is designed to provide visual inspection capabilities of the carrier pipe by navigating down existing casing vents, therefore eliminating costly and disruptive excavation. This system will help pipeline operators to comply with Federal and State safety guidelines and assess the condition of transmission lines more quickly and cost-effectively than existing methods.
Since 2011, NYSEARCH/NGA and Honeybee Robotics have developed several prototypes of the pipe inspection robot and field-tested them in infrastructure owned and operated by NYSEARCH/NGA member companies. This new phase of development and testing will advance the design of the navigation system, sensor package, and operator interface to improve navigation and inspection capabilities in the pipeline environment.
“This miniature robot, with NYSEARCH patent pending, is designed to travel through casing systems’ vents and negotiate turns to get inside the annular space of the casing and visualize the full surface of the carrier pipe,” said Daphne D’Zurko, Executive Director, NYSEARCH /VP, RD&D, Northeast Gas Association.
“We look forward to this new development phase to further enhance the design while optimizing the manufacturing costs and inspection capabilities of this innovative system.” “We are excited to support NYSEARCH/NGA and its members by addressing this important inspection challenge in a new phase of development,” said Jason Herman, Vice President of Honeybee Robotics. “This phase will enable us to improve performance in the demanding navigation environment, make the tool even easier for inspection teams to operate, and take steps to scale up production for future commercial use of this unique inspection robot.”
Over the summer and fall of 2014, NYSEARCH/NGA and Honeybee Robotics completed inspection and navigation testing at natural gas transmission sites owned by PG&E and National Grid. The current tethered robot design, incorporating patent-pending drivetrain technology, proved effective at entering a surface-level vent pipe, navigating dozens of feet and around 90-degree elbows in the vent pipe, entering the annular space inside the cased section, and inspecting the pipe while obtaining video data.
Inspection of natural gas transmission lines is important for companies to monitor their assets and protect against corrosion and other potential threats. In addition, Federal regulations from the Pipeline Hazardous Materials Safety Administration (PHMSA) require integrity assessments of pipes. This robotic pipe inspection system will help NYSEARCH/NGA member companies comply with these regulations in a cost-effective, non-disruptive manner.
