21、) 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 repr
22、esented 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 ar
23、e 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 Internation
24、al 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.

26、 v Introduction The petroleum and natural gas industries involve large capital investment costs as well as operational expenditures. The profitability of these industries is dependent upon the reliability, availability and maintainability of the systems and components that are used. Therefore, for o
27、ptimal production availability in the oil and gas business, a standardized, integrated reliability approach is required. The concept of production assurance, introduced in this International Standard, enables a common understanding with respect to use of reliability technology in the various life-cy
28、cle phases and covers the activities implemented to achieve and maintain a performance level that is at its optimum in terms of the overall economy and, at the same time, consistent with applicable regulatory and framework conditions. Annexes A through I are for information only. Licensed CopyChines

30、l and natural gas industries Production assurance and reliability management 1 Scope This International Standard introduces the concept of production assurance within the systems and operations associated with exploration drilling, exploitation, processing and transport of petroleum, petrochemical a
31、nd natural gas resources. This International Standard covers upstream (including subsea), midstream and downstream facilities and activities. It focuses on production assurance of oil and gas production, processing and associated activities and covers the analysis of reliability and maintenance of t
32、he components. It provides processes and activities, requirements and guidelines for systematic management, effective planning, execution and use of production assurance and reliability technology. This is to achieve cost- effective solutions over the life cycle of an asset-development project struc
33、tured around the following main elements: production-assurance management for optimum economy of the facility through all of its life-cycle phases, while also considering constraints arising from health, safety, environment, quality and human factors; planning, execution and implementation of reliab
34、ility technology; application of reliability and maintenance data; reliability-based design and operation improvement. For standards on equipment reliability and maintenance performance in general, see the IEC 60300-3 series. This International Standard designates 12 processes, of which seven are de
35、fined as core production- assurance processes and addressed in this International Standard. The remaining five processes are denoted as interacting processes and are outside the scope of this International Standard. The interaction of the core production-assurance processes with these interacting pr
36、ocesses, however, is within the scope of this International Standard as the information flow to and from these latter processes is required to ensure that production-assurance requirements can be fulfilled. This International Standard recommends that the listed processes and activities be initiated
37、only if they can be considered to add value. The only requirements mandated by this International Standard are the establishment and execution of the production-assurance programme (PAP). 2 Normative references The following referenced documents are indispensable for the application of this document

41、n cause failure failures of different items resulting from the same direct cause, occurring within a relatively short time, where these failures are not consequences of each other 3.1.3 corrective maintenance maintenance that is carried out after a fault recognition and intended to put an item into
42、a state in which it can perform a required function See IEC 60050-191:1990, Figure 191-10 2, for more specific information. 3.1.4 deliverability ratio of deliveries to planned deliveries over a specified period of time, when the effect of compensating elements, such as substitution from other produc
43、ers and downstream buffer storage, is included See Figure G.1 for further information. 3.1.5 design life planned usage time for the total system NOTE Design life should not be confused with MTTF (3.1.25), which is comprised of several items that may be allowed to fail within the design life of the s
44、ystem as long as repair or replacement is feasible. 3.1.6 down state internal disabled state of an item characterized either by a fault or by a possible inability to perform a required function during preventive maintenance 2 NOTE This state is related to availability performance. 3.1.7 downtime tim
45、e interval during which an item is in a non-working state 2 NOTE The downtime includes all the delays between the item failure and the restoration of its service. Downtime can be either planned or unplanned. 3.1.8 downstream business process, most commonly in the petroleum industry, associated with
46、post-production activities EXAMPLES Refining, transportation and marketing of petroleum products.

47、of an item to perform a required function NOTE 1 After failure, the item has a fault. NOTE 2 “Failure” is an event, as distinguished from “fault”, which is a state. 3.1.10 failure cause root cause circumstances during design, manufacture or use that have led to a failure 2 NOTE Generic failure cause
48、 codes applicable for equipment failures are defined in ISO 14224:2006, B.2.3. 3.1.11 failure data data characterizing the occurrence of a failure event 3.1.12 failure mode effect by which a failure is observed on the failed item NOTE Failure-mode codes are defined for some equipment classes in ISO
