California, US: Esri collaborated with Technical Toolboxes, Inc. (TTI), to help gas distribution companies in the US access GIS data for distribution integrity management plan (DIMP) submissions. The TTI is the same company which had developed the Simple, Handy, Risk-Based Integrity Management Plan (SHRIMP).
DIMP regulations, put forth by the US Department of Transportation Pipeline and Hazardous Materials Safety Administration, require each US gas utility to report on its risk-based approach to pipeline management.
Bill Meehan, Esri director of utility solutions said, “By linking SHRIMP to Esri’s GIS, gas utilities can now use two industry-leading solutions together.” Adding further Meehan stated that the GIS technology will enable gas distribution companies to connect integrity management data with geographic location to reduce risk, improve safety, and help satisfy DIMP requirements.
GIS will enable utilities to section a gas distribution system based on geography and other criteria defined by the operator. Additionally, GIS will provide information such as leak repair history and equipment condition for each section, thereby reducing data input requirements.
Vernon Mallu, the TTI SHRIMP project manager explained, “The SHRIMP-GIS interface will facilitate the input of data required by SHRIMP. Operators will still be required to review and complete threat assessments. However, many of the tedious tasks—collecting and reviewing repair records and tickets and entering this information—will be eliminated or reduced by using the data already available in the GIS.”
