Pipeline Integrity Management System

Pipeline Integrity Management (PIMS) system is all activities (monitoring, control, documentation, etc) to assure that the pipeline remains in a Safe Condition throughout its operational lifetime Technically, it can be said that PIMS is a mean to assure that the pipeline satisfies all relevant Design Criteria.

    Perspective VS Risk Based Methods
  • Traditionally, Pipeline integrity managed by prescriptive requirements by authorities. Today’s industry tends to reduce operational cost in one side but maintaining reliability and safety for personnel, assets and environment. As an answer of the trend risk as a decision tool becoming major issues.
    Industries trends are:
    • Going from prescriptive rules to goal setting/functionality base on risk assessment
    • Use of risk based approaches to optimize revenue without jeopardizing safety or environment
    • Used in all project phase Pipeline integrity is ensuring a pipeline is safe and secure. It involves all aspects of a pipeline’s design construction, operation, inspection, management and maintenance
    Component of PIMS
  • In summary the RBI approach adopted by DNV involves the following steps:
    • Review of equipment Database
    • Analyze the data
    • Evaluate Each Equipment Item with regard to: Probability of Failure, Consequence, Risk
    • Evaluation of Management Systems
    • Evaluation of Inspection Plan
    • Focus Inspection Efforts
    • Identify Opportunities for: Risk Reduction, Cost Reduction
    Benefit of PIMS
  • Consistent use of PIM according to codes/standards and best practice and consistent documentation of this gives several benefits:
    • Document the risk of the pipelines, which hence can be used to priorities actions
    • Can save inspection costs (if excessive inspections) and improve operations
    • The benefit of inspection and other actions can be documented
    • Make the operator aware of the condition of the pipeline, the company risk exposure and critical contributions to risk
