Petroleum and natural gas industries - Drilling and production equipment - Offshore conductor design, setting depth and installation (ISO 3421:2022)
This document specifies the requirements and recommendations for the design, setting depth and installation of conductors for the offshore petroleum and natural gas industries. This document specifically addresses:
— design of the conductor, i.e. determination of the diameter, wall thickness, and steel grade;
— determination of the setting depth for three installation methods, namely, driving, drilling and cementing, and jetting;
— requirements for the three installation methods, including applicability, procedures, and documentation and quality control.
This document is applicable to:
— platform conductors: installed through a guide hole in the platform drill floor and then through guides attached to the jacket at intervals through the water column to support the conductor, withstand actions, and prevent excessive displacements;
— jack-up supported conductors: a temporary conductor used only during drilling operations, which is installed by a jack-up drilling rig. In some cases, the conductor is tensioned by tensioners attached to the drilling rig;
— free-standing conductors: a self-supporting conductor in cantilever mode installed in shallow water, typically water depths of about 10 m to 20 m. It provides sole support for the well and sometimes supports a small access deck and boat landing;
— subsea wellhead conductors: a fully submerged conductor extending only a few metres above the sea floor to which a BOP and drilling riser are attached. The drilling riser is connected to a floating drilling rig. The BOP, riser and rig are subject to wave and current actions while the riser can also be subject to VIV.
This document is not applicable to the design of drilling risers.

Industries du pétrole et du gaz naturel - Équipements de forage et de production - Conception des tubes conducteurs en mer, profondeur de mise en place et installation (ISO 3421:2022)
Le présent document spécifie les exigences et les recommandations relatives à la conception, la profondeur de mise en place et l'installation des tubes conducteurs destinés aux industries du pétrole et du gaz naturel en mer. Le présent document couvre plus particulièrement les aspects suivants:
— conception du tube conducteur, c'est-à-dire détermination du diamètre, de l'épaisseur de paroi et de la nuance d'acier;
— détermination de la profondeur de mise en place pour trois méthodes d'installation, à savoir battage, forage et cimentation, et injection;
— exigences pour les trois méthodes d'installation, notamment l'applicabilité, les modes opératoires, la documentation et le contrôle qualité.
Le présent document est applicable:
— aux tubes conducteurs de plate-forme: installés à travers un trou de guidage dans le plancher de forage de la plate-forme, puis à travers les guides fixés à la jacket par intervalles à travers la colonne d'eau pour soutenir le tube conducteur, supporter les actions et empêcher les déplacements excessifs;
— aux tubes conducteurs soutenus par une plate-forme auto-élévatrice: un tube conducteur temporaire utilisé uniquement lors des opérations de forage, qui est installé par une plate-forme de forage auto-élévatrice. Dans certains cas, le tube conducteur est mis en tension par des dispositifs de mise en tension fixés à l'appareil de forage;
— aux tubes conducteurs auto-porteurs: un tube conducteur autoportant en porte-à-faux installé dans des eaux peu profondes, habituellement des profondeurs d'eau d'environ 10 m à 20 m. Il fournit le seul soutien au puits et soutient parfois un petit pont d'accès et débarcadère;
— aux tubes conducteurs de tête de puits sous-marins: un tube conducteur entièrement immergé s'étendant seulement de quelques mètres au-dessus du fond marin et auquel sont fixés un BOP et un riser de forage. Le riser de forage est relié à un appareil de forage flottant. Le BOP, le riser et l'appareil de forage sont soumis aux actions des vagues et des courants, tandis que le tube prolongateur peut également être soumis aux VIV.
Le présent document n'est pas applicable à la conception des risers de forage.
Industrija za predelavo nafte in zemeljskega plina - Vrtalna in proizvodna oprema - Načrtovanje plavajočih vodnikov, nastavitev globine in vgradnja (ISO 3421:2022)
Ta dokument podaja zahteve za načrtovanje, nastavitev globine in vgradnjo vodnikov, ki se uporabljajo v industriji za predelavo nafte in zemeljskega plina na odprtem morju. Ta dokument obravnava:
– načrtovanje vodnika, tj. določitev premera, debeline stene in vrste jekla;
– določanje nastavitve globine za tri načine vgradnje, in sicer vgradnjo z zabijanjem, vrtanjem/cementiranjem in vodnim curkom;
– zahteve glede vgradnje za metode vgradnje, tj. načela izbire, delovne postopke in parametre.
Ta dokument se uporablja za:
– ploščadne vodnike: vgradijo se skozi vodilno luknjo v odru vrtalne ploščadi in se nato z vodili, nameščenimi v ustreznih razmikih vzdolž vodnega stolpca pritrdijo na plašč tako, da omejujejo vpliv meteoroloških in oceanografskih dejavnikov na vodnike ter preprečujejo prevelike vzdolžne premike;
– vodnike, podprte z dvigalom: začasni vodniki, ki se uporabljajo samo med postopki vrtanja in jih vgradi dvižna vrtalna ploščad. V nekaterih primerih se vodnik napne z napenjali, ki so pritrjena na vrtalno ploščad;
– prosto stoječe vodnike: samonosilni kesoni v konzolnem načinu, vgrajeni v plitvih vodah, katerih globina običajno dosega približno od 10 do 20 m. Zagotavlja edino podporo za vrtino ter včasih podpira manjšo ploščad za dostop in privez čolnov;
– Podvodni vodniki v ustju vrtine: vodniki, ki so v celoti pod vodno gladino in se dvigajo le nekaj metrov nad morskim dnom.
Ta dokument se ne uporablja za dvižne cevi za vrtanje.
