ISO 13623:2017 PDF

Overview

ISO 13623:2017 - Petroleum and natural gas industries - Pipeline transportation systems specifies functional requirements and gives recommendations for the design, materials, construction, testing, operation, maintenance and abandonment of pipeline systems used in the petroleum and natural gas industries. The standard covers on‑land and offshore rigid metallic pipelines that connect wells, production and process plants, refineries and storage facilities (including pipeline sections inside facility boundaries). It applies to new pipeline systems and to modifications of existing systems (not intended to be retroactive for in‑service assets) and provides a basis for safe pipeline design, commissioning, operation and end‑of‑life abandonment.

Key topics and technical requirements

ISO 13623:2017 addresses the full pipeline life cycle with emphasis on safety, integrity and environmental protection. Major technical topics include:

• System definition and fluid categorization - defining pipeline function and classifying transported fluids for safety and design decisions.
• Hydraulic analysis and pressure control - requirements for flow modelling, pressure containment and overpressure protection.
• Design of pipeline and primary piping - route selection, on‑land and offshore surveys, load cases (functional, environmental, construction, accidental), strength and stability criteria, spanning and supports.
• Testing and commissioning - pressure test media, test levels, durations and acceptance criteria.
• Integrity, operation and maintenance - monitoring, pigging design, section isolation valves, integrity management and records.
• Stations and terminals - layout, safety, security, piping (primary/secondary), emergency shutdown, metering, compressor and storage considerations.
• Materials and coatings - material selection, sour‑service considerations, fracture toughness, fabrication, marking and documentation.
• Health, safety and environment (HSE) & competence assurance - management of HSE risks and competence verification for personnel.

Practical applications

ISO 13623:2017 is used to:

• Design new on‑land and offshore pipeline systems to recognized safety and engineering practices.
• Define technical requirements for procurement, welding, fabrication and coating of rigid metallic pipelines.
• Establish testing, commissioning and pressure testing programs.
• Guide pipeline operators in integrity management, pigging programs, maintenance planning and abandonment strategies.
• Support risk assessments, route and crossing planning, and regulatory compliance documentation.

Who should use this standard

• Pipeline designers and engineers
• Asset owners and operators in petroleum and natural gas industries
• Construction and fabrication contractors
• Integrity, maintenance and HSE managers
• Regulatory bodies and inspectors
• Engineering consultants and project managers

Related standards

ISO 13623 is typically applied alongside material, welding and testing standards and applicable national regulations for pipeline design, fabrication and operation (industry standards for pipe metallurgy, welding, non‑destructive testing and subsea engineering). Use ISO 13623 as the functional framework for safe pipeline transportation system practice.
