| Project Detail |
Legacy pipe malfunctions create operating risk and legal liability for utilities, negatively impact system owners’ financial performance, and are costly to gas consumers. Today, repairing legacy pipes involves excavating and replacing them, typically with high-density polyethylene pipe. Replacement costs range from $1-10 million per mile, depending on the pipe’s location (rural vs. urban), complexity of the excavation, and costs for restoring roads. Utilities also incur costs whenever gas service is disrupted for repairs. REPAIR seeks to eliminate the highest cost components, excavation and restoration, by rehabilitating pipes without their removal—in essence, by automatically constructing a new pipe within the old.
Project Innovation + Advantages:
The team led by White River Technologies will deliver an improved capability to reliably detect, locate, and position natural gas distribution mains and associated utilities in pipe corridors. The proposed solution connects elements of positioning and information management and (1) advances core electromagnetic (EM) and data management technologies, (2) establishes a physics-based process for large standoff EM for pipe detection and robot location, and (3) employs mixed-reality visualization. Additionally, the project includes a comprehensive, inclusive, and robust REPAIR data management and visualization system to provide an integrated and interactive data delivery system.
Potential Impact:
REPAIR seeks to eliminate the highest pipe rehabilitation cost components, excavation and restoration, by repairing pipes without their removal. |
