21、ional 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. Interna
22、tional 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 r
23、ules 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 a
24、t 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 20815 was prepared by Technical Committee ISO/T
25、C 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries. This corrected version of ISO 20815:2008 incorporates the following corrections: 3.1.13 “(t + t)” modified to “t, (t + t)”; 3.1.46, Equation (1) symbols and definitions modified; Clause G.2, E

The profitability of these industries is dependent upo
27、n the reliability, availability and maintainability of the systems and components that are used. Therefore, for optimal production availability in the oil and gas business, a standardized, integrated reliability approach is required. The concept of production assurance, introduced in this Internatio
28、nal Standard, enables a common understanding with respect to use of reliability technology in the various life-cycle 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
29、applicable regulatory and framework conditions. Annexes A through I are for information only.

30、ment 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 and natural gas resources. This International Standard covers upstream (i
31、ncluding 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 the components. It provides processes and activities, requirements and gu
32、idelines 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 structured around the following main elements: production-assurance management
33、 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 reliability technology; application of reliability and maintenance data; reliab
34、ility-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 defined as core production-assurance processes and addressed in this Intern
35、ational 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 processes, however, is within the scope of this International Standard as th
36、e 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 only if they can be considered to add value. The only requirements mandate
37、d 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.

39、Terms, definitions and abbreviated terms 3.1 Terms and definitions For the purpose of this document, the following terms and definitions apply. 3.1.1 availability ability of an item to be in a state to perform a required function under given conditions at a given instant of time, or in average over
40、a given time interval, assuming that the required external resources are provided See Figure G.1 for further information. 3.1.2 common cause failure failures of different items resulting from the same direct cause, occurring within a relatively short time, where these failures are not consequences o
41、f each other 3.1.3 corrective maintenance maintenance that is carried out after a fault recognition and intended to put an item into a state in which it can perform a required function See IEC 60050-191:1990, Figure 191-102, for more specific information. 3.1.4 deliverability ratio of deliveries to
42、planned deliveries over a specified period of time, when the effect of compensating elements, such as substitution from other producers 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
43、 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 system 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 pe
44、rform a required function during preventive maintenance2NOTE This state is related to availability performance. 3.1.7 downtime time interval during which an item is in a non-working state2NOTE The downtime includes all the delays between the item failure and the restoration of its service. Downtime
45、can be either planned or unplanned. 3.1.8 downstream business process, most commonly in the petroleum industry, associated with post-production activities EXAMPLES Refining, transportation and marketing of petroleum products.

46、failure termination of the ability 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 f
47、ailure2NOTE Generic failure cause 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 f
48、or some equipment classes in ISO 14224:2006, B.2.6. 3.1.13 failure rate limit, if this exists, of the ratio of the conditional probability that the instant of time, T, of a failure of an item falls within a given time interval, t, (t + t) and the length of this interval, t, when t tends to zero, giv
49、en that the item is in an up state at the beginning of the time interval See ISO 14224:2006, Clause C.3 for further explanation of the failure rate. NOTE 1 In this definition, t may also denote the time to failure or the time to first failure. NOTE 2 A practical interpretation of failure rate is the number of failures relative to the corresponding operational time. In some cases, time can be replaced by units of use. In most cases, the reciprocal of MTTF (3.1.25) can be used as the predictor for the failure rate, i.e.
