Drilling installation: handling system, method for independent operations
Drilling installation comprising a cantilever with a drilling floor for performing drilling operations; further comprising an independent operations handling system arranged for handling equipment underneath the drilling floor independent of the drilling operations on the drilling floor, wherein the independent operations handling system comprises a handling element for cooperation with the equipment to be handled, wherein the handling element is extendible underneath the cantilever.
1. A cantilever for mounting on a drilling installation, the cantilever comprising a drilling floor for performing drilling operations and further comprising an independent operations handling system,
wherein, in an extended position of the cantilever, in which the cantilever extends outside of an area of a deck of the drilling installation, the independent operations handling system is configured for handling equipment on a jacket or well platform that is underneath the cantilever and outside of said area of the deck of the drilling installation.
2. The cantilever of claim 1 , wherein the independent operations handling system is configured for handling said equipment, independent of said drilling operations on the drilling floor.
3. The cantilever of claim 1 , wherein the independent operations handling system is movable with respect to the cantilever.
4. The cantilever of claim 3 , wherein the independent operations handling system is translatable with respect to the cantilever.
5. The cantilever of claim 1 , wherein the independent operations handling system is mounted to a bottom side of the cantilever.
6. The cantilever of claim 5 , wherein the independent operations handling system is mounted to a rail at said bottom side of the cantilever.
7. The cantilever of claim 6 , wherein the independent operations handling system is movable in a forward and a backward direction along the rail.
8. The cantilever of claim 1 , wherein the independent operations handling system comprises a handling element for cooperation with the equipment.
9. The cantilever of claim 8 , wherein the handling element is movable underneath the cantilever.
10. The cantilever of claim 8 , wherein the handling element provides hoisting and/or lifting capacity.
11. The cantilever of claim 8 , wherein the handling element is a lifting hook or a clamping mechanism.
12. The cantilever of claim 8 , wherein the handling system comprises an arm and the handling element is at a free end of the arm.
13. The cantilever of claim 1 , wherein the cantilever is translatable above the deck of the drilling installation.
14. The cantilever of claim 13 , wherein the cantilever is translatable in an X-direction only, is translatable in both the X-direction and a Y-direction, or is translatable in the X-direction and rotatable.
15. The cantilever of claim 1 , wherein, in a retracted position of the cantilever, the cantilever is positioned substantially above the area of the deck of the drilling installation.
16. A drilling installation, said drilling installation having mounted thereon the cantilever of claim 1 .
17. A cantilever for mounting on a drilling installation, the cantilever comprising a drilling floor for performing drilling operations and being extendible outside of an area of a deck of the drilling installation, the cantilever further comprising an independent operations handling system configured for handling equipment underneath the cantilever, independent of the drilling operations,
wherein the independent operations handling system comprises a handling element for cooperation with the equipment, said handling element being movable underneath the cantilever, and
wherein the independent operations handling system is mounted to a rail at a bottom side of the cantilever.
18. The cantilever of claim 17 , wherein the handling element provides hoisting and/or lifting capacity.
19. The cantilever of claim 17 , wherein the handling element is a lifting hook or a clamping mechanism.
20. A cantilever for mounting on a drilling installation, the cantilever comprising a drilling floor for performing drilling operations and further comprising an independent operations handling system,
wherein, in an extended position of the cantilever, in which the cantilever extends outside of an area of a deck of the drilling installation, the independent operations handling system is configured for handling equipment underneath the cantilever, and
wherein the independent operations handling system is movable with respect to the cantilever.
21. The cantilever of claim 20 , wherein the independent operations handling system is translatable with respect to the cantilever.
22. The cantilever of claim 20 , wherein the independent operations handling system is mounted to a bottom side of the cantilever.
