ISO 13628-11:2007(E) © ISO 2007 – All rights reserved vForeword 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 13628-11 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. This first edition of ISO 13628-11 cancels and replaces ISO 10420:1994, which has been technically revised. ISO 13628 consists of the following parts, under the general title Petroleum and natural gas industries — Design and operation of subsea production systems: ⎯ Part 1: General requirements and recommendations ⎯ Part 2: Unbonded flexible pipe systems for subsea and marine applications ⎯ Part 3: Through flowline (TFL) systems ⎯ Part 4: Subsea wellhead and tree equipment ⎯ Part 5: Subsea umbilicals ⎯ Part 6: Subsea production control systems ⎯ Part 7: Completion/workover riser systems ⎯ Part 8: Remotely Operated Vehicle (ROV) interfaces on subsea production systems ⎯ Part 9: Remotely Operated Tool (ROT) intervention systems ⎯ Part 10: Specification for bonded flexible pipe ⎯ Part 11: Flexible pipe systems for subsea and marine applications A part 12 dealing with dynamic production risers, a part 13 dealing with remotely operated tools and interfaces on subsea production systems and a part 15 dealing with subsea structures and manifolds are under preparation.



ISO 13628-11:2007(E) vi © ISO 2007 – All rights reserved Introduction This part of ISO 13628 is based on API RP 17B and on matching ISO procedures and API procedures. This ISO standard has been technically updated and revised to cater for the needs of the international oil and natural gas industries. This part of ISO 13628 provides information complementary to ISO 13628-2 and ISO 13628-10. Users of this International Standard should be aware that further or differing requirements can 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 can 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.

This part of ISO 13628 supplements ISO 13628-2 and ISO 13628-10, which specify minimum requirements for the design, material selection, manufacture, testing, marking and packaging of unbonded and bonded flexible pipe, respectively. This part of ISO 13628 applies to flexible pipe assemblies, consisting of segments of flexible pipe body with end fittings attached to both ends. Both bonded and unbonded pipe types are covered. In addition, this part of ISO 13628 applies to flexible pipe systems, including ancillary components. The applications covered by this part of ISO 13628 are sweet- and sour-service production, including export and injection applications. This part of ISO 13628 applies to both static and dynamic flexible pipe systems used as flowlines, risers and jumpers. This part of ISO 13628 does cover, in general terms, the use of flexible pipes for offshore loading systems. NOTE Refer also to Reference [30] for offshore loading systems. This part of ISO 13628 does not cover flexible pipes for use in choke and kill lines or umbilical and control lines. 2 Normative references The following referenced documents are indispensable for the application of this document.
