Applying experience from many pipeline systems to:
- Maintain up-to-date pipeline data that reflects current system characteristics
- Confidently meet regulatory compliance and safety standards
Every operator, as required by 49 CFR 192, must confirm or reconfirm the maximum allowable operating pressure (MAOP) of previously untested natural gas transmission pipelines and pipelines lacking necessary material or operational records. Operators are also required to reconfirm the MAOP of those pipeline segments and gather any necessary material property records required by the code, where the records needed to substantiate the MAOP are not traceable, verifiable, and complete (TVC).
A systematic approach for MAOP confirmation/reconfirmation is applied across an entire pipeline system to ensure not only an efficient application of regulatory requirements but also the establishment of a solid, knowledge-based understanding of critical asset characteristics through their entire lifecycle.
G2-IS applies a comprehensive method for MAOP determination or reconfirmation that covers the following main process areas:
- Data discovery & review: Assess initial data and define the optimal framework to determine the systems and records quality and availability as well as the program’s scope of work.
- Record quality determination: Discuss customer specific needs with the proper stakeholders (record and system owners) to assess individual systems and determine the quality and level of confidence of the records on those systems.
- Records governance: Establish the agreed-upon approach to “TVC” a system, with proper application of the record matrix (defining completeness verification, confidence level, and quality determination/grading).
- Mitigation: Define the most effective approach to resolve TVC gaps, by addressing two areas:
- Regulatory compliance: Plan to mitigate record gaps in the context of keeping compliance with regulations.
- Safety: Approach to determine MAOP for gap segments using default values.
This framework creates the structure to build a Pipeline Feature List (PFL) to bring all the data and values together and allow for MAOP calculation and confirmation against a pipeline’s system design maximum allowable operating pressure.
G2-IS will ensure that a robust, compliant, and effective MAOP determination program is provided utilizing subject matter expertise within G2-IS for:
- TVC/MAOP determination: Cost-effective implementation of the G2-IS TVC method for a specific system or enterprise.
- Database and PFL: Development of a robust and digital PFL, using proprietary technology, with all appropriate records and corresponding MAOP calculations and confirmation, including data views, reporting, and dashboards.
- Data support tools: Application of digital analytical tools to support the process of record governance, digitalization, and management.
- Additional support: Focused consultation to identify issues and gaps, recommend resolutions, and formulate a planned approach to prioritized mitigation to ensure all required assets have TVC records.
