ISO 19345-1:2019 PDF

Overview

ISO 19345-1:2019 - Petroleum and natural gas industry - Pipeline transportation systems - Pipeline integrity management specification - Part 1: Full-life cycle integrity management for onshore pipeline - specifies requirements and recommendations for managing the integrity of onshore, rigid steel pipeline systems across their entire life cycle. The standard addresses integrity from design and construction through commissioning, operation, maintenance and abandonment, focusing on pipelines used to connect wells, production and process plants, refineries and storage facilities.

Key topics and technical requirements

ISO 19345-1:2019 structures an effective pipeline integrity management program and covers these core technical areas:

• Full life‑cycle approach: requirements for feasibility, design, procurement, fabrication, construction, commissioning, operation, modification and abandonment phases.
• Integrity management program elements: program scope, policy, roles and responsibilities, records and document control, management of change, audits and training.
• Risk assessment: segmentation, threat identification, probability and consequence assessment, and periodic reassessment to determine risk and inspection priorities.
• Inspection and monitoring: in‑line inspection (ILI) planning and baseline inspections, aboveground inspection, non‑destructive testing (NDT), river crossing inspections, excavation verification and monitoring strategies.
• Integrity assessment: fitness‑for‑purpose evaluations, defect data analysis, residual strength and remaining life assessment, plus reporting requirements.
• Mitigation and remediation: preventive measures, maintenance planning, repair criteria and failure management.
• Special technical methods: guidance on pressure testing, direct assessment and acceptance criteria for inspection data.
• Limitations and applicability: applies to rigid steel pipelines only; not for flexible pipelines or other materials (e.g., glass‑reinforced plastics). Non‑pipe elements are not covered specifically.

Practical applications

ISO 19345-1:2019 is used to:

• Develop or enhance a pipeline integrity management program aligned with international best practice.
• Plan and prioritize inspection and maintenance activities using risk‑based approaches.
• Prepare fitness-for-service and remaining life assessments to justify continued operation or remediation.
• Support regulatory compliance, asset management and safety cases.
• Inform procedures for pressure testing, ILI campaigns and direct assessment execution.

Who should use this standard

• Pipeline operators and asset managers in the petroleum and natural gas sector
• Integrity engineers, inspection planners and maintenance teams
• Design and construction engineers involved in pipeline projects
• Regulators, auditors and consultants supporting pipeline risk and safety assessments
• Contractors and service providers delivering ILI, NDT and remediation services

Related standards

• ISO 13623 (pipeline design and construction standards) - ISO 19345-1 complements and enhances design/construction from an integrity perspective.
