Petroleum and natural gas industries - Fixed steel offshore structures (ISO 19902:2020)
This document specifies requirements and provides recommendations applicable to the following types of fixed steel offshore structures for the petroleum and natural gas industries:
? caissons, free-standing and braced;
? jackets;
? monotowers;
? towers.
In addition, it is applicable to compliant bottom founded structures, steel gravity structures, jack-ups, other bottom founded structures and other structures related to offshore structures (such as underwater oil storage tanks, bridges and connecting structures).
This document contains requirements for planning and engineering of the design, fabrication, transportation and installation of new structures as well as, if relevant, their future removal.
NOTE 1 Specific requirements for the design of fixed steel offshore structures in arctic environments are presented in ISO 19906.
NOTE 2 Requirements for topsides structures are presented in ISO 19901-3; for marine operations in, ISO 19901‑6; for structural integrity management, in ISO 19901-9 and for the site-specific assessment of jack-ups, in ISO 19905‑1.

Industries du pétrole et du gaz naturel - Structures en mer fixes en acier (ISO 19902:2020)
Le présent document spécifie des exigences et fournit des recommandations applicables aux types suivants de structures en mer fixes en acier pour les industries du pétrole et du gaz naturel :
— caissons, autoportants et ancrés ;
— jaquettes ;
— tours mono ;
— tours.
En outre, elle est applicable à des structures élastiques prenant appui sur le fond marin, à des structures en acier posées par gravité, à des plateformes auto-élévatrices, à d'autres structures prenant appui sur le fond marin et à d'autres structures associées aux structures en mer (telles que des citernes sous-marines de stockage de pétrole, des ponts et des structures de joint).
Le présent document contient des exigences pour la planification et l'ingénierie de la conception, de la fabrication, du transport et de l'installation de nouvelles structures de même que, le cas échéant, de leur enlèvement futur.
NOTE 1 Des exigences spécifiques concernant la conception de structures en mer fixes en acier dans les environnements arctiques sont présentées dans l'ISO 19906.
