The Acellent system was developed, tested, and validated in the selected gas pipeline industry sector, PG&E in San Ramon, California. Modules of diagnostic data acquisition hardware were developed, lab tested, and placed at scheduled intervals along the pipeline to collect and analyze signals from the sensor layer and transmit them to the back office in real-time. Visible and invisible damage in the pipeline structures were detected by the system, which provided operators with the location and magnitude of defects to facilitate effective mitigation actions.
Acellent Technologies, Inc. (Acellent) was selected and awarded a contract through a competitive solicitation to demonstrate a real-time active pipeline integrity detection (RAPID) system developed by Acellent. Acellent's structural health monitoring (SHM) technology utilizes a network of distributed piezoelectric sensors/actuators to monitor and evaluate the condition of a structure. Pacific Gas and Electric Company (PG&E) coordinated closely with the Acellent team to develop the necessary system requirements and demonstrated the RAPID system within the PG&E pipeline network. This project used SHM technology to provide an early indication of any physical damage to the pipeline so it can be assessed with minimal labor involvement prior to a potential structural failure. The SHM technology consists of a network of distributed piezoelectric sensors/actuators embedded on a thin dielectric film that can be applied to new or existing pipelines.
Early damage detection using low cost technology will lower costs of gas pipeline operations and management.
Early and timely damage detection will improve reliability of gas pipelines in California.
Early and timely damage detection and adequate measures to prevent pipeline failure will improve safety of gas pipelines in California.
