Oil and gas industries including low carbon energy — Design and operation of subsea production systems — Part 1: General requirements and recommendations
This document provides general requirements and recommendations for the development and operation of subsea production/injection systems, from the concept development phase to decommissioning and abandonment. Flexible pipe standards form part of the API 17-series of documents (see 4.3.3); however, this document (technically equivalent to API RP 17A 6th edition) does not generally cover flowlines/pipelines or production/injection risers (associated with flowlines/pipelines). These components form part of a complete subsea production system (SPS), as shown in Figure 1.
Industries du pétrole et du gaz, y compris les énergies à faible teneur en carbone — Conception et exploitation des systèmes de production immergés — Partie 1: Exigences générales et recommandations
Le présent document fournit des exigences générales et des recommandations pour le développement et l'exploitation des systèmes de production/d'injection immergés, depuis la phase de développement du concept jusqu'au démantèlement et à l'abandon. Les normes relatives aux canalisations flexibles font partie intégrante des documents de la série API 17 (voir 4.3.3) ; toutefois, le présent document (techniquement équivalent à la 6e édition de l'API RP 17A) ne couvre généralement pas les conduites d'écoulement/canalisations ou les colonnes montantes de production/injection (associées aux conduites d'écoulement/canalisations). Ces composants font partie d'un système de production immergé (SPS) complet, comme le montre la Figure 1.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
