Ancor Pipeline Integrity offers integrated services for survey data alignment and analysis to support corrosion control, pipeline diagnostics, and repair planning. This service ensures accurate correlation between field surveys, in-line inspection (ILI) data, and geospatial references, improving the reliability of integrity assessments and the effectiveness of mitigation strategies.

All data sets, whether from indirect inspections, cathodic protection evaluations, or repair activities, are aligned to a consistent reference system using the ILI centerline as baseline. Corrections are applied to stationing and GPS coordinates to ensure positional accuracy and meaningful data comparison.

SCOPE OF SERVICES:

1. Alignment of survey data with the ILI centerline as the primary reference.

2. Application of correction factors to synchronize stationing and adjust GPS coordinates.

3. Integration and processing of the following survey types:

• Close Interval Survey (CIS)

• Direct Current Voltage Gradient (DCVG)

• Pipeline Current Mapping (PCM)

• Shorted casing tests

• Soil resistivity readings

• CP Annual Surveys

• CP Troubleshooting surveys

• Coating electrical conductance surveys

• DC stray current and AC interference diagnostics

4. Correlation of repair data, whether planned or completed, with ILI anomalies and indirect inspection results.

5. Geospatial mapping of survey data for visualization and reporting.

DELIVERABLES:

1. Aligned data sets with corrected stationing and GPS coordinates

2. Integrated survey reports with a summary of results and interpretations

3. Comparative overlays of ILI and indirect survey data

4. Identification of discrepancies, trends, and potential high-risk zones

5. Recommendations for further inspection, verification digs, or mitigation

6. Exportable data files and alignment tables for client systems.

BENEFITS:

1. Improves the accuracy and usefulness of field survey data

2. Enables better correlation between ILI anomalies and external diagnostics

3. Supports effective repair planning and risk prioritization

4. Reduces uncertainty in spatial analysis and decision-making

5. Facilitates regulatory compliance and audit documentation
