PHMSA Inspection Preparation

In preparation for an inspection, a gas pipeline operator asked Celerity to validate data from thousands of leak repairs. Celerity performed validation checks and subjective review where necessary on data such as repair type, facility classification and leak cause (e.g., corrosion, fracture, third-party damage, material failure, etc.). Celerity not only provided corrections to the leak data, but also identified numerous gaps in existing leak repair documentation procedures, including; the absence of a check to ensure a pressure test was performed after every repair, a gap in recording the condition of exposed pipe, and lack of a standard process to obtain exact locations for other utilities before excavating. Our work not only improved the quality of existing leak repair data, but also allowed the management team to improve their leak repair process prior to the official inspection by the state regulatory agency.
