EN ISO 13628-11:2008 PDF

Overview

EN ISO 13628-11:2008 - Petroleum and natural gas industries: Flexible pipe systems for subsea and marine applications provides guidance for the design, analysis, manufacture, testing, installation and operation of flexible pipes and flexible pipe systems used in onshore, subsea and marine environments. It covers assemblies (flexible pipe segments with end fittings) and complete flexible pipe systems including ancillary components. Both unbonded and bonded pipe types are addressed. The standard applies to sweet- and sour-service production (export and injection), for static and dynamic applications as flowlines, risers and jumpers, and generally addresses offshore loading systems. It does not cover choke/kill lines or umbilical/control lines.

Key Topics

• Scope and definitions: Terms, symbols and system descriptions for flexible pipe assemblies and systems.
• Pipe and component description: Construction details for bonded and unbonded flexible pipes and associated ancillary components (end fittings, connectors).
• Design considerations: Design overview, failure modes, design criteria and load cases for subsea and marine service.
• Materials: Requirements and test procedures for polymer/elastomer and metallic materials used in flexible pipes (separate guidance for bonded vs unbonded pipes).
• Analysis: Recommended analysis techniques, load modelling, and evaluation of global response for dynamic and static systems.
• Prototype testing & qualification: Classification, test programmes, protocols and special test procedures (including high-temperature and polymer exposure tests covered in normative annexes).
• Manufacturing & quality: Manufacturing requirements, marking, storage and production controls for flexible pipe assemblies.
• Handling, transportation & installation: Best practices for safe handling, transport, installation, pre-commissioning and commissioning.
• Retrieval, reuse & integrity monitoring: Procedures for retrieval, assessment for reuse and methods for condition monitoring and integrity management.

Applications

EN ISO 13628-11:2008 is intended for professionals involved in:

• Subsea production system design and engineering (flowlines, risers, jumpers)
• Flexible pipe manufacturing and quality assurance
• Offshore operators and asset owners managing export and injection systems (sweet and sour service)
• Subsea installation contractors, ROV/installation teams and commissioning engineers
• Inspection, integrity management and lifecycle maintenance teams

Use cases include specifying flexible pipe assemblies for production risers, designing dynamic riser systems, qualifying end fittings and planning installation/maintenance sequences.
