An apparatus for facilitating the connection of tubulars using a top drive, said apparatus comprising a motor (4, 4') for rotating a tool (30) for drivingly engaging a tubular, and means (3) for connecting said motor (4, 4') to said top drive, the apparatus being such that, in use, said motor (4, 4'
An apparatus for facilitating the connection of tubulars using a top drive, said apparatus comprising a motor (4, 4') for rotating a tool (30) for drivingly engaging a tubular, and means (3) for connecting said motor (4, 4') to said top drive, the apparatus being such that, in use, said motor (4, 4') can rotate one tubular with respect to another to connect said tubular.
The invention claimed is: 1. A method of facilitating making of a connection between an upper tubular and a lower tubular, comprising: engaging the upper tubular with a tubular engagement tool of a top drive having a suspension unit; engaging a lower end of the upper tubular with an upper end of th
The invention claimed is: 1. A method of facilitating making of a connection between an upper tubular and a lower tubular, comprising: engaging the upper tubular with a tubular engagement tool of a top drive having a suspension unit; engaging a lower end of the upper tubular with an upper end of the lower tubular; rotating the upper tubular via the tubular engagement tool, thereby threading the tubulars to form the connection; torquing the connection via the tubular engagement tool; and compensating for movement of the upper tubular with the suspension unit during the threading. 2. The method of claim 1, further comprising adjusting the suspension unit to move the upper tubular in at least two planes. 3. The method of claim 1, wherein compensating for movement of the upper tubular comprises pneumatically compensating via at least one piston and cylinder arrangement. 4. A method of facilitating making of a connection between an upper tubular and a lower tubular, comprising: engaging the upper tubular with gripping assembly having at least one radially displaceable element for gripping the upper tubular, wherein the gripping assembly is connected to a top drive having a suspension unit; compensating for weight of the upper tubular to accommodate movement of the upper tubular while engaged by the gripping assembly; engaging a lower end of the upper tubular with an upper end of the lower tubular to form the connection therebetween; and delivering torque to the upper tubular via the gripping assembly. 5. The method of claim 4, wherein engaging the lower end of the upper tubular with the upper end of the lower tubular includes rotating the upper tubular, thereby threading the tubulars together. 6. The method of claim 4, further comprising compensating for movement of the upper tubular with the suspension unit during the threading. 7. The method of claim 4, further comprising adjusting the suspension unit to move the upper tubular in at least two planes. 8. The method of claim 4, wherein compensating for weight of the upper tubular comprises compensating via at least one piston and cylinder arrangement. 9. The method of claim 4, wherein compensating for weight of the upper tubular is pneumatic. 10. A method of facilitating making of a connection between an upper tubular and a lower tubular, comprising: providing a make-up unit having a top drive, a suspension unit and a tubular engagement tool; engaging the upper tubular with the tubular engagement tool; engaging a lower end of the upper tubular with an upper end of the lower tubular; rotating the upper tubular with the top drive via the tubular engagement tool, thereby threading the tubulars to form the connection; torquing the connection with the top drive via the tubular engagement tool; and compensating for movement of the upper tubular with the suspension unit during the threading. 11. The method of claim 10, further comprising adjusting the suspension unit to move the upper tubular in at least two planes. 12. The method of claim 10, wherein compensating for movement of the upper tubular comprises pneumatically compensating via at least one piston and cylinder arrangement. 13. The method of claim 10, wherein compensating for movement of the upper tubular comprises compensating via at least one piston and cylinder arrangement. 14. The method of claim 10, wherein the tubular engagement tool includes at least one gripping element displaceable in a radial direction for engagement with a wall of the upper tubular during engaging the upper tubular.
