“Integrity Management”

Pipeline operators need create

integrity management plans that

minimize the overall costs of pipeline

operation and that address the

consequences

associated

with

a

leak:

• loss of life and property,

environmental damage,

business losses, reputation

Oil and Gas Pipeline Failures by Year --Typical Industry Sector Performance

Internal Corrosion Failures

Internal corrosion failure frequencies are increasing in spite of expenditures associated withmitigation, monitoring, & inspection. Root cause is lack of technical alignment of mitigation

and inability of monitoring program to identify changes to the hazard state.

Consideration of Detrimental Flow Conditions

-Critical inclination angle not exceeded-Stratified water film

-Good film movement-Relatively easy to mitigate






Consideration of Detrimental Flow Conditions

-Critical inclination angle exceeded

-Onset of high liquid fraction to 50%-Higher likelihood of reduced localized pH

-Severe stagnant pools allow bacteria / solids to settle

-Potential for onset of steady-state slugging

-increase in water film shear stress

-More difficult to mitigate

-Conditions prevail at locations of pipeline failuresoil
