A method for facilitating assembly and erection of a drilling rig, the drilling rig comprising a drill floor (12,112) and a substructure (16,116), the method comprising the steps of positioning a rig structure (17,40,140) adjacent the drill floor (12,112) with a vehicle (T), attaching said rig structure (40,140) to a movement apparatus (23p,26s,26t,27s,27t) of a support appa-ratus (21,22) of said drill floor (12,112) and activating said movement apparatus (23p,26s,26t,27s,27t) to move the rig structure (17,40,140) from the vehicle (T) sufficient to allow said vehicle to move away, and activating drill floor raising apparatus (16a) to raise the drill floor (12,112) and rig structure (17,117,40,140) to an operating height. A drilling rig comprising a drill floor (12,112) and a rig structure (17,117,40,140), characterised in that said drill floor (12,112) further comprises a support apparatus (21,22) comprising movement apparatus (23p,25,26), the support apparatus (21,22) for supporting the rig structure (17,117,40,140) from a side of the drill floor (12,112) and the movement apparatus (23p,26s,26t,27s,27t) for moving the rig struc-ture (17,117,40,140), the support apparatus (17,117,40,140) further comprising locking apparatus (Ps) for locking the rig structure (17,117,40,140) relative to the rig floor (12,112).
La présente invention concerne un procédé pour faciliter lassemblage et lélévation dune installation de forage, linstallation de forage comportant un plancher de forage (12, 112) et une sous-structure (16, 116). Le procédé comprend les étapes suivantes : le positionnement dune structure dinstallation (17,40, 140) adjacente au plancher de forage (12, 112) avec un véhicule (T), la fixation de ladite structure dinstallation (40, 140) à un appareil de déplacement (23p,26s,26t,27s,27t) dun appareil de support (21, 22) dudit plancher de forage (12, 112) et lactivation dudit appareil de déplacement (23p,26s,26t,27s,27t) pour déplacer la structure dinstallation (17,40,140) depuis le véhicule (T) suffisamment pour permettre léloignement du véhicule, et lactivation de lappareil de levage (16a) de plancher de forage pour soulever le plancher de forage (12, 112) et la structure dinstallation (17,117,40,140) jusquà une hauteur de fonctionnement. Linvention concerne également une installation de forage comportant un plancher de forage (12, 112) et une structure dinstallation (17,117,40,140), caractérisées en ce que ledit plancher de forage (12, 112) comporte également un appareil de support (21, 22) comprenant un appareil de déplacement (23p, 25, 26), lappareil de support (21m 22) permettant dassurer le support de la structure dinstallation (17,117,40,140), à partir du plancher de forage (12, 112) et lappareil de déplacement (23p,26s,26t,27s,27t) permettant dassurer le déplacement de la structure dinstallation (17,117,40,140), lappareil de support (17,117,40,140) comportant en outre un appareil de verrouillage (Ps) permettant de verrouiller la structure dinstallation (17,117,40,140) par rapport au plancher de forage (12, 112).
