Pipeline Anomalies

“Single  Defects“

“Combined  Defects“

In-Line Inspection Technologies

UT – ultrasonic wallthickness MFL – magnetic flux leakage

Complementary technologies for corrosion assessment, high resolution geometry survey and inertial measurement brought together in single inspection tools ...

Geo – extended geometry service XYZ – IMU mapping of pipe route

How to evaluate which Anomaly is a Safety Concern…  

Pipeline Anomaly Evaluation

“Straightforward Rules“

“Decision Tree“

e.g. B31G; RStreng calculation of safe maximum pressure based on dimensions of corrosion

e.g. cfr 49 – 192 or 195 complex decision tree with different consequences (remediation schedule) understanding of multiple threads and environmental factors (HCA)

Isolated ILI considerations

• ILI Defect parameters • Operating Conditions • No influence of environmental factors or inspection history

Basic screening identifying immediate repairs utilizing ILI Vendors Reporting Software.

Practical Prioritization Methods

Immediate Concerns are usually reported in a Preliminary Report and require  actions  “ASAP”  (max.  5  days). • Metal Loss > 80% • Top side Dent + Metal Loss • … Those  defects  usually  don’t  require  further  pre-assessment, but immediate  action…so  no  spatial  interaction  required. This process goes further and utilizes advanced Data Management to optimally tackle scheduled and monitored conditions.

Practical Prioritization Methods

API 1160

Inspection History, Threat Interaction & Environmental Factors

• ILI Defect parameters • Inspection History • External Events / Threats • Influencing Geographical Factors

Accurate and focused process requiring stringent data collection and integration processes and sophisticated integrity assessment / query tools.

Practical Prioritization Methods

To interact ILI defects with external features, the accuracy of the alignment to known installations is usually sufficient.

Linear and Spatial Alignment

Just getting rid of the «Slippage Factor»

To interact ILI defects from consecutive runs, a weld-to-weld and considerations of the o’clock  position  is  mandatory.  

Linear and Spatial Alignment

Weld-to-Weld as basis for «Corrosion Growth»

• ILI vendors often implement specific export queries/lists as requested by the operator

• Such  queries  usually  do  not  include  features  “around”  the  pipeline,  as  “Data  Evaluation”  doesn’t  know  about  those  (unless  provided  by  the operator in an aligned manner)

The Spatial Component

“High  Consequence Areas“

“Foreign Line Crossings“

Which Parameters matter in the Decision Tree?

Advanced process following ILI evaluation: • GIS Processing: All non-ILI features have to be processed along

the pipeline route to allow for interpretation and intersection • PIMS Processing: ILI data is intersected with each other AND with

linear features to calculate critical defect parameters and to apply queries

Automated Workflow as Part of ILI Reporting

Assessment results are interactively presented and can directly be related to any external feature for optimal judgement on rehabilitation activities ...

Joint decision Reporting Platform: • ALL environmental input parameters • ALL types of defects • External Inspections • Far beyond ILI standard software

Record Keeping and Demonstrating Compliance

Field activities should be tracked in their entirety...

• What was the input information?

• What was the decision tree?

• Who decided for the action?

• Which task was assigned?

• Who executed it? • What was the

outcome?

Record Keeping and Demonstrating Compliance

Thinking about Accuracy for Immediate and Future Decisions...

• Utilization of Field Verifications for immediate run accuracy / acceptance checks

• Application of accuracy buffers for future Corrosion Growth Studies

Depending  on  what  the  operator’s  IT/GIS  environment looks like, there are various delivery options: 1) Enterprise GIS available: Spatial format

delivery (Geodatabases, Shape Files, PODS ILI Exchange)

2) Pipeline Integrity Management Software required: Implementation of ROAIMS environment

3) No supporting Hardware available: Hosted solution directly fed by ROSEN alongside an ILI campaign

Conclusion

Inline Inspection Data provides the Operator with a massive amount of highly accurate data along the pipeline. Immediate decisions can be taken based on Vendors Reporting

Software, if all concerned Parameters are accurately handed over to Data Evaluation Team.

Advanced software tools are made available (installed or hosted) to support decision making process and lifecycle data integration.

Further analysis can be quickly taken over by ROSEN in case accurate route and spatial surroundings are provided.

Service is provided compatible to Enterprise Pipeline GIS as all results can be directly imported and/or further be processed inside ROAIMS.

Thank you for joining this presentation. We look forward seeing you at our Booth!
