ISO 13628-10:2005

Overview

ISO 13628-10:2005 - "Petroleum and natural gas industries - Design and operation of subsea production systems - Part 10: Specification for bonded flexible pipe" defines minimum technical requirements for bonded flexible pipe used in subsea production systems. The standard sets out requirements for safe, dimensionally and functionally interchangeable bonded flexible pipe assemblies (pipe body segments with end fittings) with a design pressure ≥ 1.5 MPa (15 bar). It focuses on design, material selection, manufacture, testing, marking and packaging, and references existing codes where applicable.

Key topics and technical requirements

• Scope and product definition: Applies to bonded (composite) flexible pipes only - it does not cover unbonded flexible pipes (see ISO 13628-2) or ancillary components.
• Design requirements: Functional and structural design parameters, loads and load effects, and system-level design to ensure interchangeability and safe operation.
• Materials and qualification: Minimum material requirements, qualification and quality assurance processes for metallic and polymeric layers; can be applied to pipes with non‑metallic reinforcement (no specific technological details are addressed).
• Manufacturing: Processes including carcass preparation, elastomer winding, reinforcement layers, curing and special processes, plus manufacturing tolerances and repair procedures.
• Testing and acceptance: Factory Acceptance Tests (FATs) such as hydrostatic pressure tests, electrical continuity/resistance tests, vacuum and kerosene tests, and dimensional/gauge checks.
• Documentation, marking and packaging: Design reports, as‑built documentation, manufacturing quality plans, operation manuals, marking and packaging requirements for traceability and safe handling.
• Limitations & exclusions: Not intended for choke and kill lines; can be used for lower pressure pipes or for applications like risers, flowlines, jumpers, loading/discharge hoses, pile hammer or flare lines, but special technological aspects for those uses are not specifically addressed.

Practical applications

• Use for subsea flowlines, risers, jumpers, offshore loading and discharge hoses in oil & gas production (sweet and sour services, export and injection).
• Suitable for static and dynamic flexible pipe installations where bonded construction is preferred.
• Intended to provide a consistent basis for procurement, manufacturing and inspection of bonded flexible pipe assemblies.

Who should use this standard

• Subsea engineers, pipeline designers and integrity specialists
• Flexible pipe manufacturers and QA/QC teams
• Procurement and equipment specification authors for offshore projects
• Testing and inspection providers performing factory acceptance tests
