Introduction
Problems discovered during integrity management program (IMP) inspections and
pipeline accident investigations
Critical knowledge gaps in current ILI technology
- Holistic analysis of ILI data – key element in a successful pipeline integrity management program
- ILI data analysis terminology
- Defects: main threats and localities of pipeline loss of integrity
Types and classification of pipeline defects
- Pipeline defects and remaining life
- Structural reliability and performance risk of pipelines with defects
- Basics of ILI technology
DAY 2
ILI – most important single method of pipeline diagnostics
- Contemporary methods of ILI
- Four stages of ILI technology
- Three possible outcomes of ILI
- International ILI qualification standards: an overview
Comprehensive review and analysis of existing international standards:
- API 1163, NACE Standard RP 0102-2002, NACE 35100, ASNT ILI- PQ 2005
- Selection of an ILI system (API 1163, RP 0102-2002, RP 35100)
- Operational characteristics & constraints (API 1163, NACE)
- ILI system performance specification (API 1163)
DAY 3
ILI systems performance verification (API 1163)
Basics of holistic ILI data acquisition, mining, analysis, and management
- ILI as a measurement system
- Main sources of variability in ILI measurements
- Typical ILI results
- Seven basic ILI performance quality metrics
- Probability of true detection (PTD)
- Probability of true location/positioning
- Probability of true identification/discrimination (PTI)
- Defect sizing accuracy metrics
- ILI system measurement and verification models
- Flow chart of holistic analysis of ILI results
- Solving the problem of missing and false ILI data
- Calibration of ILI tools and results of runs
- Field verification of ILI data
- Number of confirmatory digs needed for corroboration of the ILI data
- Contractual criteria for defect reports
- ILI quality management
- Cost/benefit analysis of ILI technology
DAY 4
Workshop # 1: Working examples of total analysis of ILI data
Implementation of ILI analysis output in risk-based pipeline IMPs
- Manual for the IMP manager: from holistic ILI data to IMP activities
- Assessment of rupture pressure (B31mod, Shell, Battelle, DNV, etc.)
- Defect-growth models
- Corrosion
- Stress corrosion
- Low-cycle fatigue cracks
- Interaction rules
- Fitness-for-purpose assessment
- Remaining lifetime
- Planning the next ILI
Case studies: application of PRIMA software
Workshop # 2: Risk-based prioritization of pipeline segments with defects for maintenance/repair: making clever decisions on actionable anomalies
Role of the human factor in ILI technology
DAY 5
Influence of ILI-induced human errors on pipeline safety and reliability
- Personnel education, qualification, certification, training and experience requirements
(as per ASNT ILI PQ requirements)
Existing approaches to quantitative assessment of human factor/errors
- Repeatability and reproducibility of ILI and field-verification measurements
- Interaction of pipeline operators, ILI vendors, and regulatory bodies
Understanding ILI tool data submitted by vendors
- Information exchange flow between operator and vendor before, during, and after ILI
- Regulators and ILI quality
- ILI tender issues
