Petroleum and natural gas industries - Site-specific assessment of mobile offshore units - Part 1: Jack-ups (ISO 19905-1:2016)
ISO 19905-1:2016 specifies requirements and guidance for the site-specific assessment of independent leg jack‑up units for use in the petroleum and natural gas industries. It addresses:
manned non-evacuated, manned evacuated and unmanned jack‑ups;
the installed phase at a specific site.
To ensure acceptable reliability, the provisions of this part of ISO 19905 form an integrated approach, which is used in its entirety for the site-specific assessment of a jack‑up.
This part of ISO 19905 does not apply specifically to mobile offshore drilling units operating in regions subject to sea ice and icebergs. When assessing a jack-up operating in such areas, it is intended that the assessor supplement the provisions of this part of ISO 19905 with the provisions relating to ice actions and procedures for ice management contained in ISO 19906.
This part of ISO 19905 does not address design, transportation to and from site, or installation and removal from site. However, it is advisable that the assumptions used in the assessment be checked against the as‑installed configuration.
To ensure that the design of the jack‑up is sound and the structure is adequately maintained, this part of ISO 19905 is applicable only to independent leg jack‑ups that either:
- hold a valid classification society certification from a recognized classification society (RCS) throughout the duration of the operation at the specific site subject to assessment; or
- have been verified by an independent competent body to be structurally fit for purpose for elevated situations and are subject to periodic inspection, both to the standards of an RCS.
NOTE 1 An RCS is an International Association of Classification Societies (IACS) member body, meeting the RCS definition given in 3.52.
Jack‑ups that do not comply with this requirement are assessed according to the provisions of ISO 19902, supplemented by methodologies from this part of ISO 19905, where applicable.
NOTE 2 Future revisions of this part of ISO 19905 can be expanded to cover mat-supported jack‑ups.
NOTE 3 Well conductors are a safety-critical element for jack‑up operations. However, the integrity of well conductors is not part of the site-specific assessment process for jack‑ups and is, therefore, not addressed in this part of ISO 19905. Annex A provides references to other publications addressing this topic.
Note 4 RCS rules and the IMO MODU code provide guidance for the design of jack-ups.
Erdöl- und Erdgasindustrie - Beurteilung von mobilen Offshore Einheiten bezüglich ihres Einsatzgebietes - Teil 1: Hubinseln (ISO 19905-1:2016)
Industries du pétrole et du gaz naturel - Évaluation spécifique au site d'unités mobiles en mer - Partie 1: Plates-formes auto-élévatrices (ISO 19905-1:2016)
L'ISO 19905-1:2016 spécifie les exigences et les lignes directrices pour l'évaluation spécifique au site d'unités de plates‑formes élévatrices à jambes indépendantes à utiliser dans les industries du pétrole et du gaz naturel. Elle traite:
des plates‑formes auto-élévatrices occupées par du personnel, non évacuées; occupées par du personnel, évacuées, et non occupées par du personnel;
de la phase installée au niveau d'un site spécifique.
Pour assurer la fiabilité acceptable, les dispositions de l'ISO 19905-1:2016 forment une approche intégrée qui est utilisée dans sa totalité pour l'évaluation liée au site d'une plate‑forme.
Elle ne s'applique pas spécifiquement aux unités de forage mobiles en mer fonctionnant dans des régions sujettes à la glace de mer et aux icebergs. Lors de l'évaluation d'une plate-forme auto-élévatrice opérant dans de telles zones, il est prévu que l'évaluateur complète les dispositions de l'ISO 19905-1:2016 par les dispositions se rapportant aux actions de la glace et par les procédures se rapportant à la gestion de la glace contenues dans l'ISO 19906.
L'ISO 19905-1:2016 ne traite pas de la conception, du transport vers et depuis un site ou de l'installation et du retrait du site. Cependant, il est recommandé que les hypothèses utilisées dans l'évaluation soient vérifiées par rapport à la configuration à l'état installé.
Pour garantir que la conception de la plate‑forme auto-élévatrice est saine et que la structure est entretenue de manière adéquate, l' ISO 19905-1:2016 est applicable seulement à des plates‑formes élévatrices à jambes indépendantes qui:
- soit détiennent une certification valide de société de classification délivrée par une société de classification (RCS) reconnue durant toute la durée de l'exploitation au niveau du site spécifique soumis à l'évaluation;
- soit ont fait l'objet d'une vérification par un organisme compétent indépendant concernant l'adéquation de la structure pour des situations en position élevée et sont soumises à une inspection périodique, toutes deux selon les normes d'une RCS.
NOTE 1 Une RCS est un membre de l'Association of Classification Societies (IACS), répondant à la définition d'une RCS donnée en 3.52.
Les plates‑formes élévatrices qui ne satisfont pas à cette exigence sont évaluées conformément aux dispositions de l'ISO 19902, complétées par des méthodologies issues de l'ISO 19905-1:2016, le cas échéant.
NOTE 2 De futures révisions de la présente partie de l'ISO 19905 peuvent être étendues afin de couvrir les plates‑formes élévatrices supportées par un plancher de stabilité.
NOTE 3 Les tubes conducteurs de puits sont un élément critique en termes de sécurité pour les opérations des plates‑formes auto-élévatrices. Cependant, l'intégrité des tubes conducteurs de puits ne fait pas partie du processus d'évaluation spécifique au site des plates‑formes auto-élévatrices et en conséquence n'est pas traitée dans l'ISO 19905-1 :2016. L'Annexe A fournit des références à d'autres publications qui traitent de ce sujet.
Note 4 Les règles RCS et le code IMO MODU fournissent des lignes directrices pour la conception des plates‑formes auto-élévatrices.
Industrija za predelavo nafte in zemeljskega plina - Ocenjevanje mobilnih naftnih ploščadi na področju postavitve - 1. del: Dvižne ploščadi (ISO 19905-1:2016)
Ta del standarda ISO 19905 določa zahteve in smernice za ocenjevanje dvižnih ploščadi s samostojnimi nogami na mestu postavitve za uporabo v industriji za predelavo nafte in zemeljskega plina. Obravnava:
a) neevakuirane dvižne ploščadi s posadko, evakuirane dvižne ploščadi s posadko in dvižne ploščadi brez posadke;
b) fazo postavitve na določenem področju.
Pri določbah tega dela standarda ISO 19905 je zaradi zagotavljanja sprejemljive zanesljivosti uporabljen celostni pristop, ki se v celoti uporablja za ocenjevanje dvižne ploščadi na področju postavitve.
Ta del standarda ISO 19905 se ne uporablja za mobilne vrtalne naftne ploščadi, ki se uporabljajo v regijah, kjer se na morju pojavljata led in ledene gore. Pri ocenjevanju dvižne ploščadi, ki obratuje na teh področjih, naj bi ocenjevalec določbe tega dela standarda ISO 19905 nadomestil z določbami v zvezi z ukrepi in postopki za ravnanje v primeru ledu iz standarda ISO 19906.
Ta del standarda ISO 19905 ne obravnava načrtovanja, prevoza na mesto ali z njega ali namestitve na mesto in odstranitve z njega. Vendar je priporočljivo, da se predpostavke, ki se uporabljajo pri ocenjevanju, preverijo glede na konfiguracijo pri namestitvi.
Da bi zagotovili zdravo zasnovo dvižne ploščadi in dobro vzdrževanje njene strukture, se ta del standarda
ISO 19905 nanaša samo na dvižne ploščadi s samostojnimi nogami, za katere velja:
– da imajo veljavno potrdilo priznanega klasifikacijskega zavoda (RCS) ves čas trajanja operacije na določenem mestu, ki je predmet presoje, ali
– da je neodvisni pristojni organ preveril, da so te dvižne ploščadi strukturno primerne za uporabo na
višini in da jih občasno preverjajo v skladu s standardi RCS.
OPOMBA 1: RCS je član mednarodnega združenja klasifikacijskih zavodov (IACS), ki ustreza opredelitvi RCS, podani v 3.52.
Dvižne ploščadi, ki niso v skladu s to zahtevo, so ocenjene v skladu z določbami standarda ISO 19902, ki jih dopolnjujejo metodologije iz tega dela standarda ISO 19905, kjer je to primerno.
OPOMBA 2: V prihodnje je mogoče, da bodo posodobitve tega dela standarda ISO 19905 razširjene na dvižne ploščadi, katerih noge počivajo na podstavku.
OPOMBA 3: Vodniki vrtine so varnostno-kritični element delovanja dvižnih ploščadi. Vendar pa celovitost vodnikov vrtin ni del postopka ocenjevanja dvižnih ploščadi na mestu namestitve in se zato ne obravnava v tem delu standarda ISO 19905. Dodatek A vsebuje reference na druge publikacije, ki obravnavajo to temo.
OPOMBA 4: Pravila RCS in kodeks IMO MODU dajejo napotke za zasnovo dvižnih ploščadi.
