Petroleum, petrochemical and natural gas industries - Reliability modelling and calculation of safety systems (ISO/TR 12489:2013)

ISO/TR 12489:2013 aims to close the gap between the state-of-the-art and the application of probabilistic calculations for the safety systems of the petroleum, petrochemical and natural gas industries. It provides guidelines for reliability and safety system analysts and the oil and gas industries.
The elementary approaches (e.g. PHA, HAZID, HAZOP, FMECA) are out of the scope of ISO/TR 12489:2013. Yet they are of utmost importance as their results provide the input information essential to properly undertake the implementation of the approaches described in ISO/TR 12489:2013: analytical formulae, Boolean approaches (reliability block diagrams, fault trees, event trees, etc.), Markov graphs and Petri nets.
ISO/TR 12489:2013 is focused on probabilistic calculations of random failures and, therefore, the non-random failures are out of the scope even if, to some extent, they are partly included into the reliability data collected from the field.

Petrokemična industrija ter industrija za predelavo nafte in zemeljskega plina - Zanesljivost modeliranja in izračun varnostnega sistema (ISO/TR 12489:2013)

To tehnično poročilo želi zapolniti vrzel med najsodobnejšo tehnologijo in uporabo verjetnostnih izračunov za varnostne sisteme v petrokemični industriji ter industriji za predelavo nafte in zemeljskega plina. Poročilo podaja smernice za analitike sistemov zanesljivosti in varnosti v industriji za predelavo nafte in zemeljskega plina, ki jim omogočajo, da:
• pravilno razumejo pomen opredelitev, uporabljenih na področju zanesljivosti;
• prepoznajo
– zadevne varnostne sisteme;
– težave, s katerimi se lahko soočijo pri obravnavanju modeliranja zanesljivosti in izračunih varnostnih sistemov;
– relevantne verjetnostne parametre, ki jih je treba upoštevati;
• so obveščeni o učinkovitih rešitvah za premagovanje težav, s katerimi se soočijo, in lahko izvedejo
izračune na podlagi relevantnih verjetnostnih parametrov;
• pridobijo zadostno znanje o načelih in ogrodjih (npr. zmožnosti in omejitve modeliranja) ustaljenih pristopov, ki se trenutno uporabljajo na področju zanesljivosti:
– analitične formule;[1][2][13]
– Boolovi:
• blokovni diagrami zanesljivosti;[4]
• drevesa napak;[5]
– zaporedni diagrami: drevesa dogodkov,[8] diagrami vzroka in posledice[10] in diagram za analizo plasti zaščite (LOPA);[9]
– modeli Markova;[6]
– Petrijeve mreže;[7]
• pridobijo zadostno znanje o načelih verjetnostnih ocen:
– analitični izračuni (izvedeni npr. na Boolovih modelih ali modelih Markova);[1][2][3]
– simulacija Monte Carlo (izvedena npr. na Petrijevih mrežah[7]);
• izberejo pristop, ki ustreza zahtevnosti zadevnega varnostnega sistema in izvedene
raziskave zanesljivosti;
• varnost in zanesljivost (npr. za zagotavljanje proizvodnje, glejte točko 3.1.1) obravnavajo v okviru istega
ogrodja zanesljivosti.
Elementarni pristopi (npr. PHA, HAZID, HAZOP, FMECA) ne spadajo v področje uporabe tega tehničnega poročila. Kljub temu so ti pristopi nadvse pomembni in jih je treba primarno uporabiti, saj njihovi rezultati zagotovijo vhodne informacije, ki so ključnega pomena za ustrezno implementacijo pristopov, opisanih v tem tehničnem poročilu: analitičnih formul, Boolovih pristopov (blokovnih diagramov zanesljivosti, dreves napak, dreves
dogodkov itn.), grafov Markova in Petrijevih mrež.
To tehnično poročilo se osredotoča na verjetnostne izračune naključnih napak, zato nenaključne napake (tj. sistematične napake, kot so poimenovane v mednarodnem izrazju na področju zanesljivosti IEV 191[14]), ne spadajo v področje uporabe tega standarda, čeprav so v določeni meri vključene v podatke o zanesljivosti, zbrane na terenu.
