5 Pipeline Anomalies Single Defects Combined Defects

6 In-Line Inspection Technologies Complementary technologies for corrosion assessment, high resolution geometry survey and inertial measurement brought together in single inspection tools addressed in One Run Corrosion / Metal Loss Mill Related Anomalies Mechanical Damage Dents and Stress Riser Ovality / ID Reduction Strain Mapping Pipeline Route 42 RoCorr. Geo 42 RoCorr UT/Geo UT ultrasonic wallthickness MFL magnetic flux leakage Geo extended geometry service XYZ IMU mapping of pipe route

7 Pipeline Anomaly Evaluation How to evaluate which Anomaly is a Safety Concern Straightforward Rules Decision Tree e.g. B31G; RStreng calculation of safe maximum pressure based on dimensions of corrosion e.g. cfr or 195 complex decision tree with different consequences (remediation schedule) understanding of multiple threads and environmental factors (HCA)

8 Practical Prioritization Methods 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.

9 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. API 1160

10 Practical Prioritization Methods 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.

11 Linear and Spatial Alignment To interact ILI defects with external features, the accuracy of the alignment to known installations is usually sufficient. Just getting rid of the «Slippage Factor»

12 Linear and Spatial Alignment To interact ILI defects from consecutive runs, a weld-toweld and considerations of the o clock position is mandatory. Weld-to-Weld as basis for «Corrosion Growth»

13 The Spatial Component 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) High Consequence Areas Foreign Line Crossings Which Parameters matter in the Decision Tree?

14 Automated Workflow as Part of ILI Reporting 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 GIS Processing Parameter depend on Prioritization Rules PIMS Processing

15 Automated Workflow as Part of ILI Reporting Sample Prioritization Query Implementation: HCA Condition Priority Target Anomaly Type 1 Metal Loss Metal Loss > 70 % 2 Dent 3 Dent 14 Gouge/ Groove Query Definition Query Details Repair Condition Top Side Dent within 5ft of any metal loss, cracking or a stress riser Top Side Dent with a Depth > 6 % Gouge or Groove > 12.5% NWT Depth >70% and HCA = YES o'clock 08:00 and 04:00 and event DENT-DWML, DENT- DWGC, IDAN-DWML, IDAN- DWGC and HCA=YES and STR=YES o'clock 08:00 and 04:00 and event IDAN-DENT and ID-Reduction >6% and HCA=YES Depth >12.5 % and event MELO-MEDA or MELO- GOUG Immediate Repair Immediate Repair Immediate Repair Scheduled Other 16 Crack Potential crack event like *CRACK* Scheduled 20 Metal Loss Metal Loss within 100 ft from a CP reading that is -850 mv event like '*MELO*' and CP_UP=YES Scheduled corrosion pitting 16 RoCorr CMFL/SIC axial anomalies ID/OD deformation IMU Reported at once No misalignment Single repair campaign HighRes MFL HighRes CMFL HighRes XYZ GEO

16 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

17 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?

18 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

19 Deliverables 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) Client Name Pipeline Name 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

20 Deliverables Cloud Services available for Advanced Reporting... No need to install «Thick ILI Reporting Software» Centralized and enterprise availablability of ILI data Immediate analysis capabilities following submission of Final Report

21 Workflow Reflection ROSEN Definition of Decision Tree Integrity Team GIS Team ILI Reporting ROSEN Boxed ILI Data ILI Reporting Vendor A Prelim / Final Report 5-10 days following Final Report results are available in any format. Data Processing Decision Tree Results Pipeline Centerline + ext. Features Enterprise GIS Hosted ROAIMS Installed ROAIMS Field Capture

22 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. Further analysis can be quickly taken over by ROSEN in case accurate route and spatial surroundings are provided. Advanced software tools are made available (installed or hosted) to support decision making process and lifecycle data integration. Service is provided compatible to Enterprise Pipeline GIS as all results can be directly imported and/or further be processed inside ROAIMS.
