Coler & Colantonio Inc. Enhances Pipeline Safety With MAOP Calculator

October 23, 2012 -- BOSTON – Pipeline specialist software and service provider, Coler & Colantonio, Inc., has introduced the MAOP Validation Calculator. This enhanced gas safety technology tool, was developed in collaboration with San Francisco based Pacific Gas & Electric Company (PG&E), one of the largest combined natural gas and electric utilities in the United States, to help improve pipeline safety across the nation.

A pipeline’s maximum allowable operating pressure (MAOP) is determined by incorporating federal and state regulatory requirements into algorithms of the MAOP Validation Calculator. The Calculator output allows for standardized report generation and the engineering analysis of MAOP validation issues. Technology enhancements include:

  • a robust and comprehensive calculator that leverages the federal and state regulations and applicable PHMSA advisory bulletins to perform MAOP validation for every pipeline component;
  • an ability to establish an audit trail of the analysis within GIS; and
  • an ability to readily generate operational and regulatory reports.

Coler & Colantonio, Inc. is a company of pipeline designers, engineers and managers that brings ‘real-world’ experience and knowledge to their clients. Coler & Colantonio, Inc. combines this unique industry understanding with Geographical Information System (GIS) expertise to provide industry leading pipeline solutions. The MAOP Calculator is the latest addition to a suite of GIS-based pipeline software that is used by oil and gas companies around the world.

Vice President of Coler & Colantonio, Inc. and pipeline industry expert, Jeff Allen has been instrumental in the development of the MAOP Calculator. He said of the product’s release:   “We are proud to have teamed with the knowledgeable and talented engineers at PG&E in the development of the MAOP Validation Calculator.  It’s rewarding for all involved to have created this product intended to further enhance and benefit natural gas pipeline safety nationwide.”

“PG&E continues to invest in the development of best-in-class technologies that will enhance pipeline safety. We have experience first-hand in using this technology to perform MAOP validation of our own pipelines,” said Sumeet Singh, senior director of Asset Knowledge Management for PG&E’s Gas Operations. “Through our collaboration with Coler & Colantonio, Inc., pipeline operators can now adopt the MAOP Validation Calculator and derive benefits that will allow them to more effectively manage critical asset information and enhance the safety of their gas transmission pipeline systems. PG&E is not only committed to enhancing the safety of its natural gas system but also sharing such solutions within the industry.”
