In-Line Inspection (ILI)

OVERVIEW

Operators have a number of options for integrity assessments of their
pipelines include coating surveys, CIS, depth of cover, direct assessment
and In-Line Inspections (ILI). Among all integrity assessment methods, ILI
yields the highest discovery of anomalies and is the most costeffective
method on a per-mile basis. ILI is your best choice to meet your regulatory,
safety, operational, and reliability demands. ENTRUST Solutions Group has a
team of highly-qualified and experienced engineers in multiple offices
across North America who provide ILI support to pipeline operators.

With decades of operational and project experience, our professionals
provide expertise in integrity management, design, engineering, corrosion
and crack control, metallurgy, and GIS data integration. ENTRUST can assist
through the life cycle of the inspection or perform specific tasks,
including:

PROJECT PLANNING AND SUPPORT

• ILI plan and procedures support
• Risk and threat assessments
• Method and tool selection
• Assessment scoping
• Contingency planning

FIELD SUPPORT

• Inspection services (retrofits; launcher/receiver installations)
• Location of above ground markers (AGM) and pig tracking
• Tool run project management and run success confirmation
• ILI verification and validation per API Std 1163
• Direct examination of anomalies including metallurgical analyses
• Repair/replacement decisions

ENGINEERING

• ILI program management
• Piggability and feasibility studies
• Software Analysis for data integration with other integrity evaluations

ILI DATA ANALYSIS AND POSTASSESSMENT

• Run-to-run analysis, comparison, and growthrate estimates for crack and
  metal loss surveys
• Global and local strain analysis for dents and deformations
• Advance analysis services (MFL, hard spots (HS) MFL, C-MFL, ultrasonic for
  crack detection/metal loss, and EMAT)
• Secondary ILI data analysis and assessments for channeling corrosion,
  narrow axial external corrosion, selective seam weld corrosion
• ILI trouble shooting, speed excursions, sensor loss, tool rotation, and
  data degradation

ILI DATA INTEGRATION SUPPORT (PIMS SOFTWARE)

ENTRUST offers the PIMS software to analyze spatial Interrelationship in
accordance with 192.917(b) “Data gathering and integration (for gas
pipelines)” and 195.452(g) “What is an information analysis? (for hazardous
liquid pipelines)”. The PIMS tool combines seamlessly GIS and Integrated
Management Solutions (IMS) to match tens-of-thousands of anomalies from
multiple ILIs. PIMS can also integrate data from other integrity surveys
including CIS, ACVG/ DCVG, Depth of Cover, Direct Assessments, AC and DC
interference information (including voltages & current densities), as well
as CP data.

The PIMS software has a complete set of tools for ILI data processing such
as clustering and grouping of anomalies, pressure-based calculations (for
corrosion and crack anomalies), anomaly prioritization, unity plots, dig
sheets generation, and others.

• Data review and anomaly classification/ prioritization
• Integrated GIS and data alignment
• Recommended dig selections
• Remaining life and re-inspection interval estimation
• Information Analysis (IA)
• Identification of preventive and mitigative measures
