Abstract

The present invention is directed to a heave compensating system for a floating drilling vessel. The system comprises: - a rig floor of the floating drilling vessel, - a drilling riser attached to a well via a wellhead, - a tubular extending through an opening of the rig floor, - a slips for holding the tubular, - a top drive and/or an elevator for holding the tubular at an upper end, - a telescopic joint comprising an outer barrel and an inner barrel, wherein the outer barrel is connected to a wellhead, and the inner barrel is telescopically arranged inside the outer barrel, - a riser tensioning system arranged between the drilling riser and the floating drilling vessel, wherein the heave compensating system comprises a draw work heave compensating system arranged between the top drive and/or elevator and the rig floor, and a slips heave compensating system for heave compensation of the slips, wherein the heave compensating systems may be synchronized, compensating for the floating drilling vessel's heave movement.

Claims (18)

1. A heave compensating system for a floating drilling vessel comprising: a rig floor (14) of the floating drilling vessel, a drilling riser (2) attached to a well (3) via a wellhead (5), a tubular (17) extending through an opening of the rig floor (14), a slips (16) for holding the tubular (17), a top drive (19) and/or an elevator for holding the tubular (17) at an upper end, a telescopic joint comprising an outer barrel (7) and an inner barrel (8), wherein the outer barrel (7) is connected to a wellhead (5), and the inner barrel (8) is telescopically arranged inside the outer barrel (7), a riser tensioning system (10) arranged between the drilling riser (2) and the floating drilling vessel, wherein the heave compensating system comprises a draw work heave compensating system (18) arranged between the top drive (19) and/or elevator and the rig floor (14), and a slips heave compensating system (25) for heave compensation of the slips (16), wherein the heave compensating systems may be synchronized, compensating for the floating drilling vesselâ s heave movement.
2. The heave compensating system according to claim 1, wherein the slips heave compensating system comprises a stroking arrangement, wherein a load from the tubular is held in the slips and transferred further to a tensioning means.
3. The heave compensating system according to claim 2, wherein the slips and an iron roughneck or casing tong (22) is located on top of the stroking arrangement.
4. The heave compensating system according to claim 2 or 3, wherein the stroking arrangement is the inner barrel (8) moving inside the outer barrel (7), and wherein the tensioning means is connected between the rig floor (8) and the inner barrel (8).
5. The heave compensating system according to claim 4, wherein the tensioning means comprises wire ropes, sheaves and wire winches.
6. The heave compensating system according to any one of the preceding claims, wherein the inner barrel (8) is connected to the slips (16) via a flex joint (12) and an inner barrel extension (23) which extends the inner barrel (8) upwards to the rig floor (14).
7. The heave compensating system according to any one of the preceding claims, wherein an iron roughneck or casing tong (22) is retractable to allow the top drive (19) to drill or run the full stand.
8. The heave compensating system according to any one of the preceding claims, wherein a riser flow diverter (13) is arranged below a riser tension ring (11) for allowing diverting flow from the well away from the rig floor (14).
9. The heave compensating system according to claim 8, wherein flow lines for mud return, riser fill and trip tank fill are attached to the riser flow diverter (13).
10. The heave compensating system according to claim 2 or 3, wherein the stroking arrangement comprises an outer guide that guides a stroking structure connected to the slips (16), wherein a riser spacer is arranged to allow the stroking structure to move vertically inside the drilling riser (2).
11. The heave compensating system according to claim 10, wherein the tensioning means comprises hydraulic cylinders, wire rope and sheaves.
12. The heave compensating system according to claim 10 or 11, wherein the stroking structure is located in a master bushing / rotary bushing location in a rotary table and extends inside a flow diverter housing and the riser spacer between a flow diverter housing and a flex joint.
13. The heave compensating system according to any one of claim 10-12, wherein a lower end of the stroking structure is located above the flex joint.
14. The heave compensating system according to any one of the preceding claims, wherein the draw work heave compensating system (18) and/or the slips compensating system (25) are Active Heave Compensating (AHC) systems.
15. The heave compensating system according to claim 14, wherein the slips heave compensating system (25) is electronically synchronized with the draw work heave compensating system (18) so that both top drive and/or elevator and slips (16) are fully synchronized and compensated for the floating drilling vesselâ s heave movement.
16. The heave compensating system according to claim 14 or 15, wherein the system comprises one or more control systems for controlling the AHC systems.
17. The heave compensating system according to claim 16, wherein a main control system controls the one or more control systems for synchronizing the system for different operational modes of the floating drilling vessel.
18. The heave compensating system according to any one of the preceding claims, wherein in operation, at least one of the draw work heave compensating system (18) and/or the slips heave compensating system (25) is active or inactive.
