PipeCraftTM Risk Models

 |
All pipeline failures, regardless of the cause, result in expenses
for the company that owns the pipeline. The causes of pipeline
failures fall into three categories:
- external corrosion,
- internal
corrosion, and
- third-party damage.
The PipeCraft™ risk
models calculate the likelihood as well as the consequence of pipeline failure,
where the likelihood is the probability of a failure occurring
on a section
of pipe, and the consequence is the amount of damage that
can occur in a selected area if a failure occurs. The results of
the calculations
are plotted on a color-coded matrix, and can be printed as a
report. |
External
Corrosion Model
PipeCraft™ provides a risk model to assess the
likelihood of failure due to external corrosion on a given pipeline.
The calculation is based
on:
- coating type and condition
- cathodic protection levels and continuity
- soil corrosivity
- soil texture and drainage
|
- operating pressure versus design pressure
- pipeline grade
- wall thickness and age
|
Internal Corrosion Models
The PipeCraft™ pipeline software provides two risk models to assess
the likelihood of failure due to internal corrosion. The first model
assesses
the
risk
to a given oil pipeline. The second model assesses the likelihood of
failure due to internal corrosion in a given carbon steel pipeline
transporting sweet or sour natural gas with produced or condensed water
and with or
without condensate.
Third-Party Damage Model
PipeCraft™ provides a risk model to assess
the likelihood that third-party damage will occur to a given pipeline.
The calculation
is based on:
- land usage
- soil depth of cover
|
- right-of-way (ROW) condition
- patrol frequency
