Petroleum and natural gas industry — Pipeline transportation systems — Pipeline integrity assessment specification

Edition date: 2023-07-11
In Force
Available languages: French, English
Summary:

This document specifies requirements and gives recommendations on the integrity assessment of pipelines of various applications as part of pipeline systems.

This document is mainly applicable to onshore pipeline systems, connecting wells, production plants, process plants, refineries and storage facilities, including any section of a pipeline constructed within the boundaries of such facilities for connection purpose, according to ISO 19345-1. The principles can also be used for offshore pipelines where applicable and practical.

This document applies to rigid, steel pipelines. It is not applicable for flexible pipelines or those constructed from other materials, such as glass-reinforced plastics.

This document does not cover all conditions which might be related to pipeline integrity. A competent pipeline integrity engineer can evaluate whether additional requirements are necessary.

This document does not cover the assessment of pipeline defect(s) found during fabrication/construction or installation, which would need to be done in accordance with the applicable standards of design, construction, material procurement and welding process applicable at that time. However, this document can be applied to the ongoing monitoring and assessment of known flaws from the time of construction.



Le présent document spécifie les exigences et fournit des recommandations pour évaluer l'intégrité des conduites destinées à diverses applications dans les systèmes de conduite.

Le présent document s'applique principalement aux systèmes de conduites à terre, au raccordement des puits, aux usines de production, aux usines de transformation, aux raffineries et aux installations de stockage, ainsi qu'à toute section de conduite construite dans les limites de ces installations à des fins de raccordement conformément à l'ISO 19345-1. Ces principes peuvent également être utilisés pour les conduites en mer dans la mesure où ils sont applicables et pratiques.

Le présent document s'applique également aux conduites en acier rigides. Il ne s'applique pas aux conduites souples, ni aux conduites réalisées à partir d'autres matériaux tels que le plastique renforcé en fibre de verre (GRP).

Le présent document ne couvre pas toutes les conditions qui pourraient être liées à l'intégrité des conduites. Un ingénieur compétent en intégrité des conduites pourra évaluer si des exigences supplémentaires sont nécessaires.

Le présent document ne couvre pas l'évaluation du ou des défaut(s) de conduites trouvé(s) lors de la fabrication/construction ou de l'installation, qui devra être effectuée conformément aux normes de conception, de construction, d'approvisionnement en matériaux et des procédures de soudage applicables à ce moment-là. Toutefois, le présent document peut être appliqué à la surveillance et à l'évaluation continues des défauts connus dès la construction.
