29、nternational 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
30、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 electrotechnica
31、l 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 bod
32、ies 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
33、 or all such patent rights. ISO 13628-7 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. ISO 13628 consists of the following parts, under the gene
34、ral 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 equipme

36、art 11: Flexible pipe systems for subsea and marine applications Recommended Practice 17G / ISO 13628-7v ISO 13628-7:2005(E) vi ISO 2005 All rights reservedIntroduction This part of ISO 13628 has been prepared to provide general requirements, recommendations and overall guidance for the user to the
37、various areas requiring consideration during development of subsea production system. The functional requirements defined in this part of ISO 13628 allow alternatives in order to suit specific field requirements. This part of ISO 13628 constitutes the overall C/WO riser system standard. Functional r
38、equirements for components comprising the system and detailed requirements for riser pipe and connector design and analysis are included herein. This part of ISO 13628 was developed on the basis of API RP 17G:1995, and other relevant documents on subsea production systems. It is necessary that the u
39、sers of this part of ISO 13628 be aware that further or different requirements might be needed for individual applications. This part of ISO 13628 is not intended to inhibit a vendor from offering, or the purchaser from accepting, alternative equipment or engineering solutions for the individual app
40、lication. This is probably particularly applicable where there is innovative or developing technology. Where an alternative is offered, it is the vendors responsibility to identify any variations from this part of ISO 13628 and provide details. Recommended Practice 17G / ISO 13628-7vi INTERNATIONAL

42、cation, testing and operation of subsea completion/workover (C/WO) riser systems run from a floating vessel. It is applicable to all new C/WO riser systems and may be applied to modifications, operation of existing systems and reuse at different locations and with different floating vessels. This pa
43、rt of ISO 13628 is intended to serve as a common reference for designers, manufacturers and operators/users, thereby reducing the need for company specifications. This part of ISO 13628 is limited to risers, manufactured from low alloy carbon steels. Risers fabricated from special materials such as
44、titanium, composite materials and flexible pipes are beyond the scope of this part of ISO 13628. Specific equipment covered by this part of ISO 13628 is listed as follows: riser joints; connectors; workover control systems; surface flow trees; surface tree tension frames; lower workover riser packag
45、es; lubricator valves; retainer valves; subsea test trees; shear subs; tubing hanger orientation systems; swivels; annulus circulation hoses; Recommended Practice 17G / ISO 13628-71 ISO 13628-7:2005(E) 2 ISO 2005 All rights reserved riser spiders; umbilical clamps; handling and test tools; tree cap
46、running tools. Associated equipment not covered by this part of ISO 13628 is listed below: tubing hangers; internal and external tree caps; tubing hanger running tools; surface coiled tubing units; surface wireline units; surface tree kill and production jumpers. 2 Normative references The following
