Oil and gas industries including lower carbon energy — Cathodic protection of pipeline transportation systems — Part 2: Offshore pipelines

This document specifies requirements and gives recommendations for the pre-installation surveys, design, materials, equipment, fabrication, installation, commissioning, operation, inspection and maintenance of cathodic protection (CP) systems for offshore pipelines for the petroleum, petrochemical and natural gas industries as defined in ISO 13623. Flexible pipelines, in-field flowlines, spools and risers are included in this document. Subsea production and injection equipment and structures are not included in this document. This document is applicable to carbon steel, stainless steel and flexible metallic pipelines in offshore service. This document is applicable to retrofits, modifications and repairs made to existing pipeline systems. This document is applicable to all types of seawater and seabed environments encountered in submerged conditions and on risers up to mean water level.

Industries du pétrole et du gaz y compris les énergies à faible teneur en carbone — Protection cathodique des systèmes de transport par conduites — Partie 2: Conduites en mer

Le présent document spécifie les exigences et donne des recommandations pour les visites d'inspection avant installation, pour la conception, pour les matériaux, pour les équipements, pour la fabrication, pour l'installation, pour la mise en service, pour l'exploitation, pour l'inspection et pour la maintenance des systèmes de protection cathodique destinés aux conduites en mer pour les industries du pétrole, de la pétrochimie et du gaz naturel telles que définies dans l'ISO 13623. Les conduites souples, les lignes de production, les manchettes et les colonnes montantes sont incluses dans le présent document. Les équipements et structures de production et d'injection sous-marines ne sont pas inclus dans ce document. Le présent document est applicable aux conduites en acier au carbone et en acier inoxydable ainsi qu'aux conduites métalliques souples utilisées en mer. Le présent document est applicable aux rénovations, modifications ou réparations effectuées sur les systèmes de conduites existants. Le présent document s'applique à tous les types d'environnements eau de mer ou fond marin rencontrés en configuration submergée et sur les colonnes montantes jusqu'au niveau d'eau moyen.
