EN ISO 19345-2:2019 PDF

Overview

EN ISO 19345-2:2019 (ISO 19345-2:2019) specifies requirements and gives recommendations for pipeline integrity management of offshore pipelines throughout the full life cycle - from feasibility, design and construction to commissioning, operation, maintenance, modifications and abandonment. The standard applies to offshore rigid steel pipelines used for transporting petroleum and natural gas and is not applicable to flexible pipelines, dynamic risers or non-steel materials (e.g., glass‑reinforced plastics). It is intended to enhance design and construction from an integrity perspective and is aligned with European adoption (EN ISO 19345-2:2019 / SIST).

Key topics and technical requirements

• Full-life cycle integrity management: Establish an Integrity Management Program (IMP) that starts at design and continues through handover, operation and abandonment.
• Scope and system limits: Defines the offshore pipeline extent (e.g., to the first valve, flange or connection above water or connection point to the installation) including pup‑piece weld limits.
• Integrity management process elements:
  • Data acquisition, review and integration
  • Risk assessment (segmentation, threat identification, probability and consequence of failure)
  • Inspection and monitoring (planning, equipment requirements, reporting)
  • Integrity assessment and remaining-life evaluation
  • Mitigation activities and failure management
  • Performance measurement, improvement and emergency response planning
• Management system elements:
  • Policy and commitment, organization, roles and responsibilities
  • Records and document control, communication, management of change
  • Management review, audits, training and skills plan
• Lifecycle phase guidance: Specific integrity considerations for feasibility, design, procurement, fabrication, transport, installation, pre‑commissioning/commissioning, handover, operation/maintenance, modification and abandonment.
• Risk-based approach: Emphasis on threat identification, probability and consequence assessments, critical consequence area analysis, and periodic reassessments.

Practical applications

• Develop or improve an IMP for offshore pipeline assets to reduce failure risk and extend asset life.
• Plan and justify inspection and monitoring strategies (including risk-based inspection).
• Integrate integrity considerations into design, procurement, fabrication and installation activities.
• Prepare handover documentation and operational procedures that support long‑term integrity.
• Inform abandonment planning and ensure safe, compliant end-of-life actions.
• Support regulatory compliance, internal audits and due-diligence during M&A.

Who should use this standard

• Pipeline operators and asset owners in the petroleum and natural gas industry
• Integrity engineers, asset integrity managers and risk assessors
• Design and construction (EPC) organizations and fabrication yards
• Inspection and maintenance contractors, surveyors and NDT providers
• Regulators, auditors and safety/compliance teams

Related standards

• Design and construction standards such as ISO 13623 (noted in the document) - where design standards differ, ISO 19345-2 enhances integrity considerations.
• Standards and guidance from ISO/TC 67 for materials, equipment and offshore structures.
