Oil and gas industries including lower carbon energy - Site-specific assessment of mobile offshore units - Part 1: Jack-ups: elevated at a site (ISO 19905-1:2023, Corrected version 2024-07)

This document specifies requirements and provides recommendation and guidance for the elevated site-specific assessment (SSA-E) of independent leg jack‑up units for use in the petroleum and natural gas industries. It addresses:
a)       occupied non-evacuated, occupied evacuated and unoccupied jack‑ups;
b)       the installed (or elevated) phase at a specific site.
It also addresses the requirement that the as-installed condition matches the assumptions used in the assessment.
This document does not address the site-specific assessment of installation and removal (SSA-I).
To ensure acceptable reliability, the provisions of this document form an integrated approach, which is used in its entirety for the site-specific assessment of a jack‑up.
When assessing a jack-up operating in regions subject to sea ice and icebergs, it is intended that the assessor supplements the provisions of this document with the relevant provisions relating to ice actions contained in ISO 19906 and procedures for ice management contained in ISO 35104. This document does not address design, transit to and from site, or installation and removal from site.
This document is applicable only to independent leg mobile jack-up units that are structurally sound and adequately maintained, which is normally demonstrated through holding a valid recognized classification society, classification certificate. Jack‑ups that do not hold a valid recognized classification society certificate are assessed according to the provisions of ISO 19902, supplemented by methodologies from this document, where applicable.
NOTE 1        Well conductors can be 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 document. See A.1 for guidance on this topic.
NOTE 2        RCS rules and the IMO MODU code (International Maritime Organisation Mobile Offshore Drilling Unit code) provide guidance for the design of jack-ups.

Öl- und Gasindustrie einschließlich kohlenstoffarmer Energieträger – Standortspezifische Beurteilung mobiler Offshore-Einheiten - Teil 1: Hubinseln: aufgeständert an einem Standort (ISO 19905-1:2023, korrigierte Fassung 2024-07)

Industries du pétrole et du gaz, y compris les énergies à faible teneur en carbone - Évaluation spécifique du site d'unités mobiles en mer - Partie 1: Plateformes auto-élévatrices : Surélévées sur un site (ISO 19905-1:2023, Version corrigée 2024-07)

Le présent document spécifie les exigences et fournit des recommandations pour l'évaluation spécifique du site en condition surélevée (SSA-E) d'unités de plateformes auto-élévatrices à jambes indépendantes à utiliser dans les industries du pétrole et du gaz naturel. Il traite :
a)       des plates‐formes auto‑élévatrices occupées et non évacuées, occupées et évacuées, et non occupées ;
b)       de la phase installée (ou surélevée sur les jambes) sur un site spécifique.
Il couvre également l'exigence d'adéquation de la configuration à l'état installé avec les hypothèses utilisées dans l'évaluation.
Le présent document ne traite pas de l'évaluation spécifique du site pour l'installation et l’enlèvement (SSA-I).
Pour assurer une fiabilité acceptable, les dispositions du présent document forment une approche intégrée qui est utilisée dans sa totalité pour l'évaluation spécifique du site d'une plateforme.
Lors de l'évaluation d'une plate‐forme auto‐élévatrice opérant dans des régions sujettes à la glace de mer et aux icebergs, il est prévu que l'évaluateur complète les dispositions du présent document par les dispositions pertinentes se rapportant aux actions de la glace contenues dans l'ISO 19906 et par les procédures se rapportant à la gestion de la glace contenues dans l'ISO 35104. Le présent document ne traite pas de la conception, du transport vers et depuis un site ou de l'installation et l’enlèvement du site.
Le présent document n'est applicable qu'aux unités de plateformes auto-élévatrices à jambes indépendantes dont la structure est saine et entretenue de manière adéquate, ce qui est normalement démontré par la mise à disposition d'un certificat de classification en cours de validité, délivré par une société de classification reconnue (RCS). Les plates‐formes auto-‑élévatrices qui ne possèdent pas de certificat en cours de validité délivré par une société de certification reconnue sont évaluées conformément aux dispositions de l'ISO 19902, complétées par des méthodologies issues du présent document, le cas échéant.
NOTE 1        Les tubes conducteurs de puits peuvent être 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 du site des plates‐formes auto‑élévatrices et, en conséquence, n'est pas traitée dans le présent document. Voir A.1 pour des recommandations sur ce sujet.
NOTE 2        Les règles RCS et le code MODU (Mobile Offshore Drilling Unit) de l'OMI (Organisation maritime internationale) fournissent des recommandations pour la conception des plateformes auto-élévatrices.

Naftna in plinska industrija, vključno z nizkoogljično energijo - Ocenjevanje premičnih naftnih ploščadi na področju postavitve - 1. del: Dvižne ploščadi (ISO 19905-1:2023)

Ta dokument določa zahteve ter podaja priporočila in smernice za ocenjevanje dvižnih ploščadi s samostojnimi nogami na področju postavitve (SSA-E) 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 (ali dviga) na določenem področju.
Prav tako obravnava zahtevo, da se mora konfiguracija pri namestitvi ujemati s predpostavkami, ki se uporabljajo pri ocenjevanju.
Ta dokument ne obravnava ocenjevanja namestitve na področje postavitve in odstranitve z njega (SSA-I).
Pri določbah tega dokumenta je zaradi zagotavljanja sprejemljive zanesljivosti uporabljen celosten pristop, ki se v celoti uporablja za ocenjevanje dvižne ploščadi na področju postavitve.
Pri ocenjevanju dvižne ploščadi, ki obratuje v območjih, kjer se na morju pojavljajo led in ledene gore, naj bi ocenjevalec določbe tega dokumenta dopolnil z ustreznimi določbami v zvezi z ukrepi in postopki za ravnanje v primeru ledu iz standardov ISO 19906 in ISO 35104. Ta dokument ne obravnava načrtovanja, prevoza na področje postavitve ali z njega ali namestitve na področje postavitve in odstranitve z njega.
Ta dokument se uporablja samo za premične dvižne ploščadi s samostojnimi nogami, ki so strukturno trdne in ustrezno vzdrževane, kar se običajno izkazuje z veljavnim certifikatom priznanega klasifikacijskega zavoda. Dvižne ploščadi, ki nimajo veljavnega certifikata priznanega klasifikacijskega zavoda, so ocenjene v skladu z določbami standarda ISO 19902, ki jih dopolnjujejo metodologije iz tega dokumenta, kjer je to primerno.
OPOMBA 1:        Vodniki vrtine so lahko varnostno-kritični element delovanja dvižnih ploščadi. Vendar pa celovitost vodnikov vrtin ni del postopka ocenjevanja dvižnih ploščadi na področju postavitve in se zato v tem dokumentu ne obravnava. Za navodila v zvezi s to temo glej točko A.1.
OPOMBA 2:        Pravila RCS in kodeks IMO MODU (International Maritime Organisation Mobile Offshore Drilling Unit) podajajo napotke za zasnovo dvižnih ploščadi.
