    Asset Management Policy

  • DNV GL 2013

    Asset Management Policy

    Challenges for Asset owners/pipeline Operators;

    Prolong lifetime of Assets in operation

    Public awareness

    Pressure from authorities

    Accidents v.s near misses

    Accommodate Renewables & Unconventionals?

    Compliance to new standards and regulation

    Operators are in the spotlight: Show me you are in control.

    Creating an umbrella for all the (inter)national- and company standards

    Example; PAS55/ISO55000

    Structure of Asset Management is better

    acknowledging what large companies do and

    want (ownership; asset management; service

    provider)

    It puts emphasis on involvement of top

    management and leadership

    Includes finance and accounting requirements

    Risk based decision has a prominent place in the

    overall asset management system

    Identify threats

    All threats to pipeline/asset integrity shall be considered

    Consider future changes in operating conditions that

    may introduce new degradation mechanisms

    (e.g. pressure fluctuations, gas quality)

    Guidance given by for example ASME B31.8S Managing System

    Integrity of Gas Pipelines:

    Time-dependent (e.g. external corrosion, internal corrosion, stress corrosioncracking)

    Stable (e.g. manufacturing, welding, equipment related defects)

    Time-independent (e.g. third party damage, incorrect operational procedure,weather related and outside force)

    Inspection planning and selection

    Inspection methods can be divided mainly into inline

    inspection (ILI) methods and aboveground surveys to be

    used in assessment methodologies.

    About 40% of the gas pipelines worldwide cannot be

    inspected inline.

    Assessment methods:

    External Corrosion Direct Assessment (ECDA)

    Dry Gas Internal Corrosion Direct Assessment (DG-ICDA)

    New developments in ILI technology

    Combining inspection results to increase accuracy of

    defect growth prediction-> leading to effective

    re-inspection

    Prioritize; risks

    Scope: Rank pipelines based on probability of

    failure and failure mode for external corrosion

    Build a failure model to determine the failure frequency of a defect

    based on the:

    leak vs. rupture (ASME B31G)

    Time to fail for a single defect

    Failure frequency of a defect (Monte Carlo simulation)

    Based on data from ILI-runs, the ECDA program, PIMS, internationaldatabases and from expert judgment

    Leading to a ranking tool to prioritize inspections based on risk:

    Incorporate consequence factors (e.g. population density, environmentaldamage, security of supply etc.)
