The Enterprise Products gas pipeline system integrity management program was developed to effectively evaluate and maintain the integrity of its pipeline systems. The gas integrity management program is designed to minimize the risks and consequences of having a gas pipeline failure that could impact populated areas and surrounding environments.
The Enterprise Products gas integrity management program follows strict federal and state pipeline regulations that require companies to develop, maintain and continuously improve integrity management programs to protect high consequence areas (HCAs).
The HCA identification process used both routine operations and maintenance activities, and input from public officials with safety or emergency response and planning responsibilities to determine the existence of HCAs. Enterprise Products also uses visible markings such as signs, facility licensing or registration data on file with Federal, State, or local government agencies, or lists or maps maintained by or available from a Federal, State, or local government agency and available to the general public to assist in HCA determination.
This process addresses the overall risk used to support various gas integrity management program elements, which may include Baseline Assessment Plan development, continuing evaluation and assessment of pipeline integrity, and identification of preventive and mitigative measures.
Enterprise Products gas pipeline integrity management personnel provide expertise in managing the risks of pipeline operations. These individuals manage the identification, assessment and mitigation of risk as it relates to pipeline design and construction, system operations and system integrity.
To assist in pipeline integrity assessments, Enterprise Products uses In Line Inspection, or "smart pig" tools or other tools capable of detecting corrosion and deformation anomalies including dents, gouges and grooves and hydrostatic pressure tests for the integrity assessment of its pipelines.
This process identifies additional measures to prevent a pipeline failure and to mitigate the consequences of a pipeline failure in a high consequence area, as well as to determine a required reassessment interval. Additional preventive and mitigative measures will be based on a risk analysis of threats identified to each pipeline segment. The reassessment determination will be based on the evaluation of available pipeline data and potential threats to the pipeline segments.
This process provides means to propose modifications to or deviations from the Enterprise Products gas integrity management program. Modifications are defined as the revision, creation, or removal of integrity management processes, procedures, or integrity assessment schedules. Significant changes to the program, program implementation, or schedules will be reported to OPS or the State or local pipeline authority as required.
Enterprise Products performs evaluations to assess the effectiveness of its gas pipeline integrity management program to determine the program effectiveness through a set of performance metrics that provides a meaningful measure of the program's performance and effectiveness in reducing risk and protecting the high consequence areas.
The communications process is key to the Enterprise Products gas pipeline integrity management program. Internal communications help ensure that employees have current information about the pipeline system and the integrity management program. External communications with regulatory entities are required to keep interested parties aware of the efforts regarding system integrity.
Quality Assurance is a mechanism used to ensure that the requirements set forth in the gas integrity management program are met through documentation, implementation, and maintenance activities.
