  • the pipe or the string is disassembled in lengths comprising three pipe elements, so-called “set-backs", which by means of a special pipe hand ⁇ ling equipment is stord vertically, for example in so-called “finger stores” provided in the vicinity of the derrick itself.
  • the known system requires three different hoisting arrangement, a first hoisting arrangement for bringing the pipe elements from a basic level to a higher level, a second hoisting arrangement for bringing pipe elements from a hori ⁇ zontal to a vertical position, and a third hoisting arrange ⁇ ment for supporting the drilling string.
  • the object of the present invention is to eliminate the above mentioned disadvantages involved in previously known pipe handling systems.
  • a device of the type as stated in the preamble which according to the invention is character ⁇ ized in that it comprises an elongated unit which at its first end is rotatably attached to the hoisting arrangement of the derrick, and which at the second end is arranged displaceably along the working deck of the drilling plat ⁇ form, the unit comprising gripping means for holding pipe lengths which preferably are constituted by pre-assembled pipe elements.
  • Such a device entails a series of advantages compared to previously known pipe handling systems.
  • assembled pipe lengths might be brought direct to and from the drilling centre.

Abstract

Le dispositif et le procédé décrits servent à placer dans une position essentiellement verticale des éléments de conduite se trouvant dans une position essentiellement horizontale, en relation notamment avec un derrick se trouvant de préférence sur une plate-forme de forage flottante. Afin de supprimer les dispositifs existants de stockage vertical de conduites et tout équipement de manipulation de conduites associé et en même temps afin d'obtenir une structure de derrick simplifiée et une plate-forme ayant un point de gravité situé à un niveau inférieur, on produit selon la présente invention un dispositif de manipulation comprenant une unité allongée (51), fixée de façon rotative au niveau de sa première extrémité (52) au dispositif de levage (53) du derrick et disposée au niveau de sa seconde extrémité (56) de façon à pouvoir se déplacer le long du plan de travail (58) de la plate-forme de forage. L'unité (51) comprend un organe de serrage (59, 64) servant à maintenir des longueurs de conduite (60, 60n) constituées de préférence par des éléments de conduite préassemblés (60a, 60b, 60c). Etant donné que le dispositif de manipulation de conduites suit le mouvement du dispositif de levage, on risque moins facilement de perdre les conduites dans le trou de forage et on obtient une économie de temps totale et un forage plus suivi.
