Petroleum and natural gas industries - Specific requirements for offshore structures - Part 1: Metocean design and operating considerations (ISO 19901-1:2015)
ISO 19901-1:2015 gives general requirements for the determination and use of meteorological and oceanographic (metocean) conditions for the design, construction and operation of offshore structures of all types used in the petroleum and natural gas industries.
The requirements are divided into two broad types:
- those that relate to the determination of environmental conditions in general, together with the metocean parameters that are required to adequately describe them;
- those that relate to the characterization and use of metocean parameters for the design, the construction activities or the operation of offshore structures.
The environmental conditions and metocean parameters discussed are:
- extreme and abnormal values of metocean parameters that recur with given return periods that are considerably longer than the design service life of the structure,
- long-term distributions of metocean parameters, in the form of cumulative, conditional, marginal or joint statistics of metocean parameters, and
- normal environmental conditions that are expected to occur frequently during the design service life of the structure.
Metocean parameters are applicable to:
- the determination of actions for the design of new structures,
- the determination of actions for the assessment of existing structures,
- the site-specific assessment of mobile offshore units,
- the determination of limiting environmental conditions, weather windows, actions and action effects for pre-service and post-service situations (i.e. fabrication, transportation and installation or decommissioning and removal of a structure), and
- the operation of the platform, where appropriate.
NOTE Specific metocean requirements for site-specific assessment of jack-ups are contained in ISO 19905‑1, for arctic offshore structures in ISO 19906 and for topside structures in ISO 19901‑3.

Industries du pétrole et du gaz naturel - Exigences spécifiques relatives aux structures en mer - Partie 1: Dispositions océano-météorologiques pour la conception et l'exploitation (ISO 19901-1:2015)
L'ISO 19901-1:2015 fournit des exigences générales relatives à la détermination et à l'utilisation des conditions océanographiques et météorologiques («océano-météorologiques») pour la conception, la construction et l'exploitation des structures en mer de tous les types utilisés dans les industries du pétrole et du gaz naturel.
Les exigences sont scindées en deux grandes catégories:
? celles liées à la détermination des conditions environnementales en général, associées aux paramètres océano-météorologiques requis pour les décrire de manière appropriée;
? celles liées à la caractérisation et à l'utilisation des paramètres océano-météorologiques pour la conception, les activités de construction ou l'exploitation des structures en mer.
Les conditions environnementales et les paramètres océano-météorologiques examinés sont:
? les valeurs extrêmes et anormales des paramètres océano-météorologiques qui réapparaissent à des intervalles de récurrence donnés nettement plus longs que la durée de vie en service de la structure;
? les distributions à long terme des paramètres océano-météorologiques, sous forme de statistiques cumulées, conditionnelles, marginales ou conjointes; et
? les conditions environnementales normales dont l'occurrence fréquente est attendue tout au long de la durée de vie en service de la structure.
Les paramètres océano-météorologiques sont applicables à:
? la détermination des actions pour la conception des nouvelles structures;
? la détermination des actions pour l'évaluation des structures existantes;
? l'évaluation spécifique au site des unités mobiles en mer;
? la détermination des conditions environnementales restrictives, des fenêtres météorologiques, des actions et de leurs effets pour les situations de pré- et post-service (c'est-à-dire la fabrication, le transport et l'installation ou la mise hors service et l'enlèvement d'une structure); et
? l'exploitation de la plate-forme, le cas échéant.
Industrija za predelavo nafte in zemeljskega plina - Posebne zahteve za naftne ploščadi - 1. del: Določila za načrtovanje in obratovanje ob upoštevanju oceanografskih in meteoroloških vidikov (ISO 19901-1:2015)
Ta del standarda ISO 19901 vsebuje splošne zahteve za določanje in uporabo meteoroloških in
oceanografskih (metoceanskih) pogojev za načrtovanje, gradnjo in delovanje naftnih ploščadi
vseh vrst, ki se uporabljajo v industriji nafte in zemeljskega plina.
Zahteve so razdeljene v dve osnovni vrsti:
– zahteve, povezane z določanjem okoljskih pogojev na splošno, skupaj z meteorološkimi in oceanografskimi parametri, ki so potrebni za njihov ustrezen opis;
– zahteve, povezane z opredelitvijo in uporabo meteoroloških in oceanografskih parametrov za načrtovanje, gradbene dejavnosti ali delovanje naftnih ploščadi.
Okoljski pogoji ter obravnavani meteorološki in oceanografski parametri so naslednji:
– ekstremne in nenormalne vrednosti meteoroloških in oceanografskih parametrov, ki se pojavljajo z določenimi povratnimi dobami, ki so precej daljše od življenjske dobe strukture,
– dolgoročne motnje meteoroloških in oceanografskih parametrov v obliki kumulativnih, pogojnih, mejnih ali skupnih statističnih podatkov o meteoroloških in oceanografskih parametrih ter
– običajni okoljski pogoji, ki naj bi se pogosto pojavili med življenjsko dobo strukture.
Meteorološki in oceanografski parametri se uporabljajo za:
– določanje ukrepov za načrtovanje novih struktur,
– določanje ukrepov za oceno obstoječih struktur,
– oceno mobilnih naftnih ploščadi na področju postavitve,
– določanje omejenih okoljskih pogojev, vremenskih oken, ukrepov in učinkov ukrepov za okoliščine pred storitvijo in po njej (tj. izdelava, promet in namestitev ali prenehanje uporabe ter odstranitev strukture) in
– po potrebi delovanje platforme.
OPOMBA: Posebne meteorološke in oceanografske zahteve za oceno dvižnih ploščadi na področju postavitve so zajete v standardu ISO 19905-1, za arktične naftne ploščadi v standardu ISO 19906 in za strukture na palubi v standardu ISO 19901-3.
