Petroleum and natural gas industries - Design and operation of subsea production systems - Part 10: Specification for bonded flexible pipe (ISO 13628-10:2006)

ISO 13628-10:2005 defines the technical requirements for safe, dimensionally and functionally interchangeable bonded flexible pipes that are designed and manufactured to uniform standards and criteria. Minimum requirements are specified for the design, material selection, manufacture, testing, marking and packaging of bonded flexible pipes, with reference to existing codes and standards where applicable.
ISO 13628-10:2005 applies to bonded flexible pipe assemblies, consisting of segments of flexible pipe body with end fittings attached to both ends.
ISO 13628-10:2005 applies to pipes with a design pressure greater than or equal to 1,5 MPa (15 bar). ISO 13628-10:2005 can be used for lower design pressure pipes, though the requirements of these pipes have not been specifically addressed.
ISO 13628-10:2005 does not cover flexible pipes of unbonded structure nor to flexible pipe ancillary components and does not apply to flexible pipes for use in choke and kill line applications..
ISO 13628-10:2005 can be applied to flexible pipes that include non-metallic reinforcing layers, though no effort was made to address the specific and unique technological aspects of this product, and to a bonded construction pipe that includes a material or layer construction that is covered in ISO 13628-2.
ISO 13628-10:2005 can be applied to flexible pipes for pile hammer, gas flare, water supply and jetting applications, though no effort was made to address the specific and unique technological aspects relating to each of these requirements.

Overview

EN ISO 13628-10:2006 (ISO 13628-10:2005) specifies technical requirements for bonded flexible pipe used in subsea production systems in the petroleum and natural gas industries. The standard defines minimum requirements for safe, dimensionally and functionally interchangeable bonded flexible pipe assemblies - including design, material selection, manufacture, testing, marking and packaging - with cross-references to existing codes where applicable. It applies primarily to bonded flexible pipes with a design pressure ≥ 1.5 MPa (15 bar) and to complete assemblies with end fittings attached.

Key Topics and Requirements

• Functional and design requirements: overall performance criteria, system-level requirements, and parameters for internal fluids and external environments.
• Design methodology: loads and load effects, pipe structure design and verification principles to ensure safe subsea operation.
• Materials and qualification: material selection, qualification testing and quality assurance for metallic and non-metallic layers where applicable.
• Manufacturing controls: production processes (carcass, elastomer winding, reinforcement layers), curing, manufacturing tolerances and repair procedures.
• Testing and acceptance: factory acceptance tests including hydrostatic, electrical continuity/resistance, vacuum and other specified checks.
• Documentation, marking and packaging: required design reports, manufacturing quality plans, as-built documentation, operation manuals, marking conventions and packaging for transport and storage.
• Scope limits: explicitly does not cover unbonded flexible pipe constructions, ancillary components, or flexible pipes for choke and kill line applications. It can be applied to bonded constructions that include non-metallic reinforcing layers, though it does not address every unique technological aspect of these variants.

Applications and Who Uses It

EN ISO 13628-10 is targeted at organizations involved in subsea infrastructure:

• Subsea engineers and designers specifying bonded flexible pipe for flowlines, risers and jumpers.
• Manufacturers and fabricators producing bonded flexible pipe assemblies and end fittings.
• Procurement, QA/QC and testing laboratories validating compliance via factory acceptance tests and material qualification.
• Operators and asset owners ensuring safe, interchangeable subsea pipe systems.
• Regulators and certification bodies referencing harmonized requirements for offshore projects.

Practical benefits include improved safety, interchangeability between vendors, clearer procurement specifications, and reduced technical disputes.

Related Standards

• ISO 13628 series (Part 1 - general, Part 2 - unbonded flexible pipe, Part 11 - flexible pipe systems for riser applications, etc.)
• EN adoption reference: EN ISO 13628-10:2006
• Historically derived from API Spec 17K (informative background)

Keywords: EN ISO 13628-10:2006, ISO 13628-10:2005, bonded flexible pipe, subsea production systems, design and manufacture, flexible pipe assemblies.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13628-10 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore
structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 4, Drilling and
production equipment.

Introduction
This part of ISO 13628 has been based on API Spec 17K, First Edition, September 2001.
Users of this International Standard should be aware that further or differing requirements might be needed for
individual applications. This International Standard is not intended to inhibit a vendor from offering, or the
purchaser from accepting, alternative equipment or engineering solutions for the individual application. This
may be particularly applicable where there is innovative or developing technology. Where an alternative is
offered, the vendor should identify any variations from this International Standard and provide details.

[30]
though the requirements of these pipes have not been specifically addressed. Reference OCIMF for
guidelines on these pipes.
1.3.2 This part of ISO 13628 does not apply to flexible pipes for use in choke and kill line applications. See
API Spec 16C for guidance on choke and kill line applications. This part of ISO 13628 can be applied to
