Oil and gas industries including lower carbon energy — Full ring ovalization test method for the evaluation of the cracking resistance of steel line pipe in sour service

Industries du pétrole et du gaz, y compris les énergies à faible teneur en carbone — Méthode d'essai de déformation du diamètre d'une conduite en acier pour évaluer sa tenue mécanique en environnement corrosif

Le présent document fournit une méthode pour déterminer la tenue mécanique des conduites en acier en environnement corrosif. La présente méthode d'essai utilise une éprouvette d'essai à pleine échelle consistant en un court tronçon de tube (une « section circulaire »), fermé de façon étanche à chaque extrémité afin de contenir la solution d'essai corrosive. La méthode d'essai s'applique à n'importe quelle conduite : sans soudure, soudée longitudinalement (avec ou sans métal d'apport), soudée en hélice, et aux soudures circulaires entre les conduites. NOTE 1 L'éprouvette consiste généralement en un tuyau, mais elle peut aussi consister en une collerette de bride ou une section de coude, ou un autre composant tubulaire ou une combinaison des éléments listés ci-avant. NOTE 2 La présente méthode d'essai peut également être utilisée pour les alliages résistant à la corrosion (CRA). La méthode d'essai utilise la déformation du diamètre par chargement mécanique afin de produire une contrainte circonférentielle, égale à la contrainte circonférentielle cible, à deux emplacements diamétralement opposés sur la surface intérieure de l'éprouvette d'essai. L'éprouvette d'essai est ensuite exposée sur un seul côté à l'environnement d'essai corrosif. NOTE 3 L'essai permet également de mesurer les vitesses de perméabilité à l'hydrogène.

Petroleum, petrochemical and natural gas industries — Qualification testing and acceptance criteria for protective coating systems under insulation

This document describes various corrosion under insulation (CUI) environments in refineries and other related industries and environments, and establishes CUI environmental categories including operating temperature ranges from −45 °C to 204 °C for topside and aboveground service only. This document specifies both established and other test methods for the assessment of coatings used for prevention of CUI for each given environment. This document also provides acceptance criteria for each CUI environment. NOTE The test results and acceptance criteria can be considered an aid in the selection of suitable coating systems. For service or peak temperatures below −45 °C an optional cryogenic test can be incorporated and for over 204 °C testing acceptance criteria can be agreed between interested parties. Additional or other test and acceptance measures are possible, but require particular agreement between the interested parties. This document covers spray-applied coatings applied on new carbon and austenitic stainless steel for use in CUI service. This document does not cover testing of sacrificial coatings, such as inorganic zinc, as these coatings can be consumed quickly in wet environments. Developing accelerated corrosion testing for what can be continuous wet service with sacrificial coatings is beyond the scope of this document. "Non-through porosity" thermal spray aluminium coatings with greater than 250 µm dry film thickness can be tested and qualified in accordance with this document. This document does not cover tape and sheet applied products for use in preventing CUI. This document does not deal with other aspects of coating degradation, such as those caused by abrasion, erosion, ultraviolet degradation or other methods that can exist given specific environment and construction methods.

Petroleum, petrochemical and natural gas industries — Production assurance and reliability management

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.

Petroleum, petrochemical and natural gas industries — Collection and exchange of reliability and maintenance data for equipment

ISO 14224:2016 provides a comprehensive basis for the collection of reliability and maintenance (RM) data in a standard format for equipment in all facilities and operations within the petroleum, natural gas and petrochemical industries during the operational life cycle of equipment. It describes data collection principles and associated terms and definitions that constitute a "reliability language" that can be useful for communicating operational experience. The failure modes defined in the normative part of this International Standard can be used as a "reliability thesaurus" for various quantitative as well as qualitative applications. This International Standard also describes data quality control and assurance practices to provide guidance for the user. Standardization of data collection practices facilitates the exchange of information between parties, e.g. plants, owners, manufacturers and contractors. This International Standard establishes requirements that any in-house or commercially available RM data system is required to meet when designed for RM data exchange. Examples, guidelines and principles for the exchange and merging of such RM data are addressed. This International Standard also provides a framework and guidelines for establishing performance objectives and requirements for equipment reliability and availability performance. Annex A contains a summary of equipment that is covered by this International Standard. ISO 14224:2016 defines a minimum amount of data that is required to be collected, and it focuses on two main issues: - data requirements for the categories of data to be collected for use in various analysis methodologies; - standardized data format to facilitate the exchange of reliability and maintenance data between plants, owners, manufacturers and contractors. The following main categories of data are to be collected: a) equipment data, e.g. equipment taxonomy, equipment attributes; b) failure data, e.g. failure cause, failure consequence; c) maintenance data, e.g. maintenance action, resources used, maintenance consequence, down time. NOTE Clause 9 gives further details on data content and data format. The main areas where such data are used are the following: 1) reliability, e.g. failure events and failure mechanisms; 2) availability/efficiency, e.g. equipment availability, system availability, plant production availability; 3) maintenance, e.g. corrective and preventive maintenance, maintenance plan, maintenance supportability; 4) safety and environment, e.g. equipment failures with adverse consequences for safety and/or environment. ISO 14224:2016 does not apply to the following: i. data on (direct) cost issues; ii. data from laboratory testing and manufacturing (e.g. accelerated lifetime testing), see also 5.2; iii. complete equipment data sheets (only data seen relevant for assessing the reliability performance are included); iv. additional on-service data that an operator, on an individual basis, can consider useful for operation and maintenance; v. methods for analysing and applying RM data (however, principles for how to calculate some basic reliability and maintenance parameters are included in the annexes).

Petroleum, petrochemical and natural gas industries — Reliability modelling and calculation of safety systems

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.
