Current PHMSA guidelines require integration of past, current,
and future pipeline integrity data:
“The rule requires that operators integrate assessment results with other pertinent information about
the risk conditions of the pipeline to uncover integrity issues that might not be evident from the
assessment data alone.“
PHMSA Protocol #3.04
“Verify that individual data elements are brought together and analyzed in their context such the
integrated data can provide improved confidence with respect to determining the relevance of specific
threats and can support an improved analysis of overall risk.”
PHMSA Gas Integrity Management Inspection Manual, C.02.f.
N-LINE is designed to reduce data management problems and streamline the data integration process while
ensuring the integrity of the information.
N-LINE was developed as a pipeline integrity data management application, allowing field technicians and
engineers to gather and process data, and perform quality control checks while integrating and aligning
both current and historical data into a single database. This software provides for the analysis of multiple
data sets in a single component, increasing both accuracy and capacity
The application handles the import, storage, and analysis of the following types of data: CIS: ON\OFF and
Static, DCVG, ACVG, Soil Resistivity, PCM, ILI, Pipeline Depth, Cell to Cell, IR Drop Survey, Test Station,
and GPS. Results are reported through digital, tabular, graphical, and Pipeline Analysis Graph Engine
(PAGE) reports formatted to client needs.
