Petroleum, petrochemical and natural gas industries - Production assurance and reliability management (ISO 20815:2018)
This document describes 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 document covers upstream (including subsea), midstream and
downstream facilities, petrochemical and associated 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. This includes a variety of business categories and associated systems/
equipment in the oil and gas value chain. Production assurance addresses not only hydrocarbon
production, but also associated activities such as drilling, pipeline installation and subsea intervention.
This document 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 structured
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, and quality;
— planning, execution and implementation of reliability technology;
— application of reliability and maintenance data;
— reliability-based technology development, design and operational improvement.
The IEC 60300-3 series addresses equipment reliability and maintenance performance in general.
This document designates 12 processes, of which seven are defined as core production assurance
processes and addressed in this document. The remaining five processes are denoted as interacting
processes and are outside the scope of this document. The interaction of the core production assurance
processes with these interacting processes, however, is within the scope of this document as the
information flow to and from these latter processes is required to ensure that production assurance
requirements can be fulfilled.
The only requirement mandated by this document is the establishment and execution of the production
assurance programme (PAP). It is important to reflect the PAP in the overall project management in the
project for which it applies.
This document recommends that the listed processes and activities be initiated only if they can be
considered to add value.

Industries du pétrole, de la pétrochimie et du gaz naturel - Assurance de la production et management de la fiabilité (ISO 20815:2018)
Le présent document introduit le concept d'assurance production dans les systèmes et les opérations liés au forage, à l'exploitation, au traitement et au transport des ressources pétrolières, pétrochimiques et en gaz naturel. Le présent document couvre les installations et les activités amont (y compris sous-marines), intermédiaires et aval, la pétrochimie ainsi que les activités associées. Il est axé sur l'assurance production relative à la production du pétrole et du gaz, sur le traitement et les opérations associées et couvre l'analyse de la fiabilité et de la maintenance des composants. Cela comprend une variété de catégories d'activité et de systèmes/équipements associés au sein de la chaîne de valeur du gaz et du pétrole. L'assurance production concerne non seulement la production des hydrocarbures, mais également les activités associées telles que le forage, l'installation de conduites et les interventions sous-marines.
Le présent document fournit des processus et des activités, des exigences et des lignes directrices pour la gestion systématique, la planification, l'exécution et l'utilisation efficaces de l'assurance production et des techniques fiabilistes. Le but est d'obtenir des solutions rentables sur tout le cycle de vie d'un projet de développement d'une installation de production structurée autour des éléments principaux suivants:
— gestion de l'assurance production pour une économie optimale de l'installation durant toutes les phases de son cycle de vie, tout en tenant compte des contraintes résultant de facteurs liés à la santé, à la sécurité, à l'environnement et à la qualité;
— planification, exécution et mise en œuvre des techniques fiabilistes;
— application des données de fiabilité et de maintenance;
— amélioration du développement, de la conception et de l'exploitation de technologies basées sur la fiabilité.
La série IEC 60300-3 a trait à la fiabilité des équipements et à l'exécution de la maintenance.
Le présent document définit douze processus, dont sept sont définis comme des processus fondamentaux de l'assurance production et sont abordés dans le présent document. Les cinq processus restants sont appelés processus en interaction et ne relèvent pas du domaine d'application du présent document. L'interaction des processus fondamentaux de l'assurance production avec ces processus interactifs s'inscrit toutefois dans le domaine d'application du présent document car le flux d'informations à destination et en provenance de ces derniers processus est requis pour s'assurer que les exigences de l'assurance production peuvent être remplies.
La seule exigence spécifiée par le présent document concerne l'établissement et l'exécution du programme d'assurance production (PAP). Il est important que le PAP se reflète dans la gestion globale du projet auquel il s'applique.
Le présent document recommande de ne lancer les processus et activités qu'il énumère que s'ils peuvent apporter de la valeur ajoutée.
Petrokemična industrija ter industrija za predelavo nafte in zemeljskega plina - Optimizacija proizvodnje in upravljanje zanesljivosti (ISO 20815:2018)
Ta dokument opisuje koncept zagotavljanja proizvodnje v sistemih in operacijah, povezanih z raziskovalnim vrtanjem, izkoriščanjem, predelavo in prevozom nafte ter petrokemičnih virov in virov zemeljskega plina. Ta dokument zajema objekte geoloških raziskav in proizvodnje (vključno s podvodnimi), transporta, predelave in trženja nafte oziroma zemeljskega plina ter petrokemične in z njimi povezane dejavnosti. Osredotoča se na zagotavljanje proizvodnje nafte in plina, predelavo in s tem povezane dejavnosti ter zajema analizo zanesljivosti in vzdrževanja komponent. To vključuje različne poslovne kategorije in pripadajoče sisteme/opremo v vrednostni verigi nafte in zemeljskega plina. Zagotavljanje proizvodnje se ne nanaša samo na proizvodnjo ogljikovodikov, temveč tudi na povezane dejavnosti, kot so vrtanje, namestitev cevovodov in podvodni posegi. Ta dokument vsebuje postopke in dejavnosti, zahteve in smernice za sistematično upravljanje, učinkovito načrtovanje, izvajanje ter uporabo tehnologije za optimizacijo in zanesljivost proizvodnje. S tem se želi doseči stroškovno učinkovite rešitve v celotnem življenjskem ciklu projekta razvoja sredstev, oblikovanega na podlagi teh glavnih elementov:
– upravljanje optimizacije proizvodnje za optimalno ekonomičnost objekta skozi vse faze njegovega življenjskega cikla ob upoštevanju omejitev v zvezi z zdravjem, varnostjo, okoljem in kakovostjo;
– načrtovanje, izvajanje in uvajanje tehnologije zanesljivosti;
– uporaba podatkov o zanesljivosti in vzdrževanju;
– razvoj, projektiranje in izboljšanje delovanja na podlagi zanesljivosti.
Skupina standardov IEC 60300-3 obravnava zanesljivost in vzdrževanje opreme na splošno. Ta dokument opredeljuje 12 procesov, od katerih jih je sedem opredeljenih kot procesi optimizacije temeljne proizvodnje. Preostalih pet procesov je označenih kot medsebojno delujoči procesi in so zunaj področja uporabe tega dokumenta. Vzajemno delovanje procesov optimizacije temeljne proizvodnje s temi interakcijskimi procesi pa je zajeto v tem dokumentu, saj je za izpolnjevanje zahtev optimizacije proizvodnje potreben pretok informacij do teh procesov in iz njih.
Edina zahteva, določena v tem dokumentu, je vzpostavitev in izvajanje programa optimizacije proizvodnje (PAP). Pomembno je, da se program optimizacije proizvodnje odraža v celotnem vodenju projekta, za katerega se uporablja.
Ta dokument priporoča, da se navedeni procesi in aktivnosti začnejo izvajati le, če projektu lahko zagotovijo dodano vrednost.

Introduction
The petroleum, petrochemical 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 optimal
production availability in the oil and gas business, a standardized, integrated reliability approach is
required.
The concept of production assurance, introduced in this document, 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 applicable regulatory and framework conditions.
Annexes A to I are for information only.

EXAMPLE 1 A usual item with an up state (3.1.59) and a down state (3.1.10) is a binary item. Components A
and B in the figure below are binary items.
EXAMPLE 2 A system made up of two redundant binary items, A and B, has four states: S (both A and B in
1
up state), S (A in up state and B in down state), S (A in down state and B in up state), S (both A and B in down
2 3 4
state). If the system is able to operate as required in states S , S and S and not able in state S , it is a binary item
1 2 3 4
with the up state class {S , S , S } and the down class {S }. This is illustrated in the Figure showing availability
1 2 3 4
behaviour of an 1oo2 system.
3.1.5
common cause failure
failures of multiple items, which would otherwise be considered independent of one another, resulting
from a single cause
Note 1 to entry: See also Notes to entry for common cause failures in ISO 14224:2016, 3.5.
[SOURCE: IEC 60050-192:2015, 192-03-18, modified — Note 1 to entry has been added.]
3.1.6
condition monitoring
obtaining information about physical state or operational parameters
Note 1 to entry: Condition monitoring is used to determine when preventive maintenance may be required.
Note 2 to entry: Condition monitoring may be conducted automatically during operation or at planned intervals.
Note 3 to entry: Condition monitoring is part of condition-based maintenance. See also ISO 14224:2016, Figure 6.
[SOURCE: IEC 60050-192:2015, 192-06-28, modified — Note 3 to entry has been added.]
3.1.7
corrective maintenance
maintenance carried out after fault detection to effect restoration
Note 1 to entry: See also ISO/TR 12489:2013, Figures 5 and 6, which illustrate terms used for quantifying
corrective maintenance.

3.1.8
deliverability
ratio of deliveries to 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
Note 1 to entry: See Figure G.1 for further information.
3.1.9
design life
planned usage time for the total system
Note 1 to entry: to entry It is important not to confuse design life with the ‘mean time to failure’ (MTTF), which
is comprised of several items that might be allowed to fail within the design life of the system as long as repair or
replacement is feasible.
3.1.10
down state
unavailable state
internally disabled state
internal disabled state
state of being unable to perform as required, due to internal fault, or preventive
maintenance
Note 1 to entry: This concept is related to a binary item (3.1.4), which can have several down states forming the
down state class of the item. All the states in the down state class are considered to be equivalent with regard to
the unavailability of the considered item.
Note 2 to entry: See also Notes to entry for down state in ISO 14224:2016, 3.15.
EXAMPLE In the figure in 3.1.4, the down state class of the system S comprises only one state {S } and the
4
system S is in down state at time t .

[SOURCE: IEC 60050-192:2015, 192-02-20, modified — Notes 1 and 2 have been added.]
3.1.11
down time
time interval during which an item is in a down state
Note 1 to entry: The down time includes all the delays between the item failure and the restoration of its service.
Down time can be either planned or unplanned (see ISO 14224:2016, Table 4).
Note 2 to entry: Down time can be equipment down time (see Figure 4 and Table 4 in ISO 14224:2016), production
down time (see Figures I.1 and I.2) or down time for other operations (e.g. drilling). It is important to distinguish
between the equipment down time itself and the down time of the plant to which the equipment belongs.

failure
loss of ability to perform as required
Note 1 to entry: A failure of an item is an event that results in a fault (i.e. a state) of that item (see 3.1.18). This is
illustrated in the figure in 3.1.50 for a binary system S comprising two redundant components A and B.

3.1.14
failure cause
root cause
set of circumstances that leads to failure
Note 1 to entry: A failure cause can originate during specification, design, manufacture, installation, operation or
maintenance of an item.
Note 2 to entry: See also ISO 14224:2016, B.2.3 and Table B.3, which define failure causes for all equipment
classes.

3.1.16
failure mode
manner in which failure occurs
Note 1 to entry: See also the tables in ISO 14224:2016, B.2.6, on the relevant failure modes, which define failure
modes to be used for each equipment class.
[SOURCE: IEC 60050-192:2015, 192-03-17, modified — Note 1 to entry has been added.]
3.1.17
failure rate
conditional probability per unit of time that the item fails between t and t + dt, provided that it has been
working over [0, t]
[SOURCE: ISO/TR 12489:2013, modified — Notes 1 to 4 to entry have been added.]
Note 1 to entry: See ISO 14224:2016, C.3 for further explanation of the failure rate.
Note 2 to entry: This definition applies for the first failure of binary items (3.1.4).
Note 3 to entry: Under the assumptions that the failure rate is constant and that the item is as good as new after
repairs the failure rate can be estimated as the number of failures relative to the corresponding accumulated up
time divided by this accumulated up time. In this case this is the reciprocal of MTTF (3.1.34). In some cases, time
can be replaced by units of use.
Note 4 to entry: The estimation of the failure rate can be based on operating time or calendar time.
3.1.18
fault
inability to perform as required, due to an internal state
Note 1 to entry: A fault of an item results from a failure, either of the item itself, or from a deficiency in an earlier
stage of the life cycle, such as specification, design, manufacture or maintenance. See latent fault (ISO 14224:2016,
3.44). The down states of items A, B and S in the figure in 3.1.46 are examples of faults.

human error
discrepancy between the human action taken or omitted and that intended
EXAMPLE Performing an incorrect action; omitting a required action.
[81]
Note 1 to entry: Discrepancy with intention is considered essential in determining human error; see Reference .
Note 2 to entry: The term “human error” is often attributed in hindsight to a human decision, action or inaction
considered to be an initiator or contributory cause of a negative outcome such as loss or harm.
Note 3 to entry: In human reliability assessment, human error is defined as any member of a set of human actions
or activities that exceeds some limit of acceptability, this being an out of tolerance action or failure to act where
[78]
the limits of performance are defined by the system (see Reference ).

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 optimal production
availability in the oil and gas business, a standardized, integrated reliability approach is required.
The concept of production assurance, introduced in this document, 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 applicable regulatory and framework conditions.
Annexes A through I are for information only.

Petroleum, petrochemical and natural gas industries —
Production assurance and reliability management
1 Scope
This document describes 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 document covers upstream (including subsea), midstream and
downstream facilities, petrochemical and associated 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. This includes a variety of business categories and associated
systems/equipment in the oil and gas value chain. Production assurance addresses not only
hydrocarbon production, but also associated activities such as drilling, pipeline installation, subsea
intervention, etc.
This document 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 structured
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, and quality;
planning, execution and implementation of reliability technology;
application of reliability and maintenance data;
reliability-based technology development, design and operational improvement.
For standards on equipment reliability and maintenance performance in general, see the IEC 60300-3
series.
This document designates 12 processes, of which seven are defined as core production assurance
processes and addressed in this document. The remaining five processes are denoted as interacting
processes and are outside the scope of this document. The interaction of the core production assurance
processes with these interacting processes, however, is within the scope of this document as the
information flow to and from these latter processes is required to ensure that production assurance
requirements can be fulfilled.
This document recommends that the listed processes and activities be initiated only if they can be
considered to add value.
The only requirement mandated by this document is the establishment and execution of the production
assurance programme (PAP). It is important to reflect the PAP document in the overall project
management in the project for which it applies.
