15、d 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 technica
16、l 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 ele
17、ctrotechnical 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 th
18、e member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of
19、normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (I
20、SO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three
21、years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of th
22、e 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.

PD CEN ISO/TS 12747:2013ISO/TS 12747:2011(E) ISO 2011 All rights reserved vIntroduction Within ISO/TC 67/SC 2 there has been a series of discussions concerning both the needs and level of prescription required to address pipeline life exten
24、sion issues. These have highlighted that operators are applying differing approaches, which leads to inefficient use of both operator and authority resources; the assessment and upgrading of existing facilities have been based on probabilistic or reliability-based methods; the level of detail delive
25、red varies. The purpose of this Technical Specification is to address the above concerns by providing a consistent approach to pipeline life extension assessment that can be applied by operators (or parties acting on their behalf) across the industry. This Technical Specification is concerned with t
26、he proof of technical integrity of the pipeline system for the justification of extended operation. Integrity management is not covered in detail. However, the interface between a PIMS and the life extension process is considered because a PIMS, where present, forms an integral part of the integrity
27、 assessment of the pipeline system; a PIMS of some form is required for operation in extended life. Factors affecting the future operability of the system but not the technical integrity, such as the loss of a control umbilical, are flagged as requiring assessment but are not addressed in full in th
28、is Technical Specification. Whilst this Technical Specification is aimed primarily at the pipeline operators, it can also be of interest to other stakeholders such as regulators approving the life extension application; members of the public affected by the life extension application, such as landow
29、ners and developers. In light of this, an overview of the life extension process and the key principles involved is given in Clause 5. The remainder of the document is intended to provide detailed guidance to those performing the life extension assessments. All guidance is provided for use in conjun
30、ction with sound engineering practice and judgment. This Technical Specification is not intended for use as a design code.

31、tation systems Recommended practice for pipeline life extension 1 Scope This Technical Specification gives guidance to follow, as a minimum, in order to assess the feasibility of extending the service life of a pipeline system, as defined in ISO 13623, beyond its specified design life. Pump stations
32、, compressor stations, pressure-reduction stations and depots are not specifically addressed in this Technical Specification, as shown in Figure 1. This Technical Specification applies to rigid metallic pipelines. It is not applicable to the following: flexible pipelines; pipelines constructed from
33、other materials, such as glass reinforced plastics; umbilicals; topsides equipment; structures and structural components. This Technical Specification is limited to life extension, which is an example of a change to the original design. Other changes, such as MAOP up-ratings, are excluded. NOTE The
34、assessment methodology is applicable to other changes to the design at the discretion of the user. 2 Normative references The following referenced documents are indispensable for the application of this document.
