Petroleum and natural gas industries - Site-specific assessment of mobile offshore units - Part 3: Floating units (ISO 19905-3:2021)
This document specifies requirements and recommendations for the site-specific assessment of mobile floating units for use in the petroleum and natural gas industries. It addresses the installed phase, at a specific site, of manned non-evacuated, manned evacuated and unmanned mobile floating units.
This document addresses mobile floating units that are monohull (e.g. ship-shaped vessels or barges); column-stabilized, commonly referred to as semi-submersibles; or other hull forms (e.g. cylindrical/conical shaped). It is not applicable to tension leg platforms. Stationkeeping can be provided by a mooring system, a thruster assisted mooring system, or dynamic positioning. The function of the unit can be broad, including drilling, floatel, tender assist, etc. In situations where hydrocarbons are being produced, there can be additional requirements.
This document does not address all site considerations, and certain specific locations can require additional assessment.
This document is applicable only to mobile floating units that are structurally sound and adequately maintained, which is normally demonstrated through holding a valid RCS classification certificate.
This document does not address design, transportation to and from site, or installation and removal from site.
This document sets out the requirements for site-specific assessments, but generally relies on other documents to supply the details of how the assessments are to be undertaken. In general:
— ISO 19901‑7 is referenced for the assessment of the stationkeeping system;
— ISO 19904‑1 is referenced to determine the effects of the metocean actions on the unit;
— ISO 19906 is referenced for arctic and cold regions;
— the hull structure and air gap are assessed by use of a comparison between the site-specific metocean conditions and its design conditions, as set out in the RCS approved operations manual;
— ISO 13624‑1 and ISO/TR 13624‑2[1] are referenced for the assessment of the marine drilling riser of mobile floating drilling units. Equivalent alternative methodologies can be used;
— IMCA M 220 is referenced for developing an activity specific operating guidelines. Agreed alternative methodologies can be used.
NOTE RCS rules and the IMO MODU code[13] provide guidance for design and general operation of mobile floating units.

Industries du pétrole et du gaz naturel - Évaluation spécifique au site d'unités mobiles en mer - Partie 3: Unités flottantes (ISO 19905-3:2021)
Le présent document spécifie les exigences et les recommandations pour l'évaluation spécifique au site d'unités mobiles flottantes destinées à être utilisées dans les industries du pétrole et du gaz naturel. Il traite de la phase en place, au niveau d'un site spécifique, d'unités mobiles flottantes occupées par du personnel non évacué, occupées par du personnel évacué et non occupées par du personnel.
Le présent document traite des unités mobiles flottantes monocoques (par exemple, structures à profil de bateau ou barges); stabilisées par des colonnes, souvent désignées par le terme «structures semi-submersibles»; ou ayant d'autres formes de coque (par exemple, cylindriques/coniques). Il n'est pas applicable aux plates-formes à lignes d'ancrage verticales tendues (TLP). Le maintien en position peut être assuré par un système d'ancrage, un système d'ancrage assisté par des propulseurs, ou un système de positionnement dynamique. L'unité peut avoir plusieurs fonctions, notamment des fonctions de forage, d'hôtel flottant, de barge, etc. Dans les situations où des hydrocarbures sont produits, des exigences supplémentaires peuvent s'appliquer.
Le présent document ne traite pas de toutes les considérations relatives au site, et certains emplacements peuvent nécessiter une évaluation supplémentaire.
Le présent document n'est applicable qu'aux unités mobiles flottantes dont la structure est saine et entretenue de manière adéquate, ce qui est normalement démontré par la tenue à jour d'un certificat de classification en cours de validité, délivré par une société de classification reconnue (RCS).
Le présent document ne traite pas de la conception, du transport vers et depuis un site ou de l'installation et du retrait du site.
Le présent document spécifie les exigences pour des évaluations spécifiques aux sites, mais s'appuie généralement sur d'autres documents pour fournir les informations détaillées sur la manière dont les évaluations doivent être effectuées. En général:
— l'ISO 19901-7 est citée en référence pour l'évaluation du système de maintien en position;
— l'ISO 19904-1 est citée en référence pour la détermination des effets des actions océano-météorologiques sur l'unité;
— l'ISO 19906 est citée en référence pour les régions arctiques et froides;
— la structure de la coque et la garde d'air sont évaluées en procédant à une comparaison entre les conditions océano-météorologiques spécifiques au site et les conditions de conception de la coque, comme indiqué dans le manuel d'exploitation approuvé par une société de classification reconnue (RCS);
— l'ISO 13624-1 et l'ISO/TR 13624-2[1] sont citées en référence pour l'évaluation des tubes prolongateurs pour les forages en mer des unités de forage mobiles flottantes. D'autres méthodologies équivalentes peuvent être utilisées;
— l'IMCA M 220 est citée en référence pour l'élaboration d'un document d'instructions d'exploitation spécifiques à l'activité. D'autres méthodologies approuvées peuvent être utilisées.
NOTE Les règles RCS et le code MODU de l'OMI[13] fournissent des recommandations pour la conception et l'exploitation générale des unités mobiles flottantes.
Industrija za predelavo nafte in zemeljskega plina - Ocenjevanje premičnih naftnih ploščadi na področju postavitve - 3. del: Plavajoče enote (ISO 19905-3:2021)
Ta dokument določa zahteve in priporočila za ocenjevanje premičnih plavajočih enot na področju postavitve za uporabo v industriji za predelavo nafte in zemeljskega plina. Obravnava fazo postavitve na določenem področju za neevakuirane premične plavajoče enote s posadko, evakuirane premične plavajoče enote s posadko in za premične plavajoče enote brez posadke.
Ta dokument obravnava premične plavajoče enote, ki imajo en trup (npr. plovila v obliki ladje ali čolna); ki so stolpično stabilizirane in se običajno imenujejo enote, ki so pol pod vodo; ali ki imajo druge oblike trupa (npr. cilindrične ali stožčaste oblike). Ne uporablja se za navpično zasidrane ploščadi. Vzdrževalni sistemi se lahko zagotovijo s sistemi zasidranja, sistemi motorno podprtega zasidranja ali z dinamičnim pozicioniranjem. Enota lahko opravlja raznovrstne funkcije, vključno z vrtanjem, plovnimi hoteli, ponudniki pomoči itd. V primerih proizvodnje ogljikovodikov lahko obstajajo dodatne zahteve.
Ta dokument ne obravnava vseh pogojev področja postavitve in določene specifične lokacije lahko zahtevajo dodatno ocenjevanje.
Ta dokument se uporablja samo za premične plavajoče naftne enote, ki so strukturno trdne in ustrezno vzdrževane, kar se običajno izkazuje z veljavnim certifikatom klasifikacije RCS.
Ta dokument ne obravnava načrtovanja, prevoza na področje postavitve ali z njega ali namestitve na področje postavitve in odstranitve z njega.
Ta dokument podaja zahteve za oceno na področju postavitve, vendar se na splošno sklicuje na druge dokumente glede podajanja podrobnosti o tem, kako naj poteka ocenjevanje. Splošno:
– sklic na standard ISO 19901-7 za ocenjevanje vzdrževalnega sistema;
– sklic na standard ISO 19904-1 za določanje učinkov meteoroloških in oceanografskih vplivov na enoto;
– sklic na standard ISO 19906 za arktična in hladna območja;
– struktura trupa in zračna reža se ocenita na podlagi primerjave meteoroloških in oceanografskih pogojev, ki so specifični za področje postavitve, ter njihovih projektnih pogojev, kot je opredeljeno v s strani RCS odobrenih navodilih za uporabo;
– sklic na standarda ISO 13624-1 in ISO/TR 13624-2[1] za ocenjevanje morskih dvižnih cevi za vrtanje na premičnih plavajočih vrtalnih enotah. Uporabijo se lahko tudi enakovredne nadomestne metodologije;
– sklic na standard IMCA M 220 za razvoj smernic za delovanje, ki so specifične za dejavnost. Uporabijo se lahko tudi dogovorjene nadomestne metodologije.
OPOMBA: Pravila RCS in kodeks IMO MODU[13] podajajo napotke za načrtovanje in upravljanje premičnih plavajočih enot.
