Abstract

System and method for heave compensated make-up and break-out of drill pipe connections, the system comprising: a blowout preventer on a wellhead, a drill string extending from the drilling vessel to a bottom of a subsea well, a sealing device provided above the blowout preventer to seal around the drill string during the drilling operation, a drilling mud return system connected below the sealing device and provided with a mud-lift pump and a mud return line extending to the drilling vessel, wherein an iron roughneck and power slips are mounted in a support frame arranged below a drill floor, the support frame is heave compensated suspended in the drill floor by a set of linear actuators, the support frame is vertically guided, and a control system is arranged for remote operation of the iron roughneck and power slips, and for hydraulic or electro-mechanical heave compensation of the support frame.

Claims (1)

P a t e n t c l a i m s
1. A system for heave compensated make-up and break-out of drill pipe connections during a drilling operation from a drilling vessel (13), the system comprising: a blowout preventer (14) locked on a wellhead (15), a drill string (7) extending from the drilling vessel (13) through the blowout preventer (14) to a bottom of a subsea well (16) in an oil and gas reservoir, a sealing device (17) provided above the blowout preventer (14), and arranged to seal around the drill string (7) during the drilling operation, a drilling mud return system (18) connected to the blow-out preventer (14) and provided with a mud-lift pump (18a) and a mud return line (18b) extending from underneath the sealing device (17) to the drilling vessel (13), c h a r a c t e r i z e d i n that an iron roughneck (1) and power slips (2) are mounted in a vertically displaceable support frame (3) arranged below a drill floor (4) of the drilling vessel (13), the support frame (3) is suspended in the drill floor (4) by a set of linear actuators (8; 9, 11) arranged for active heave compensation of the support frame (3), the support frame (3) is vertically guided in a guiding arrangement (5), and a control system (19) is arranged for remote operation of the iron roughneck (1) and power slips (2), and for hydraulic or electro-mechanical heave compensation of the support frame (3). The system according to claim 1 , wherein the drill string (7) is extending through a marine riser (20) suspended in the drilling vessel (13). The system according to claim 2, wherein the sealing device (17) is provided inside the marine riser (2). The system according to claim 1 , wherein the drill string (7) is extending through open water, and the sealing device (17) is connected to an upper portion of the blowout preventer (14). The system according to claim 1 , wherein the set of linear actuators comprises several hydraulically operated cylinders (8). The system according to claim 1 , wherein the set of linear actuators comprises several wire-ropes (9) extending from one or more winches (11). A method of heave compensated make-up and break-out of drill pipe connections during drilling of a subsea well (16), in connection with a need to at least reduce bottom hole pressure variations induced by vertical motion of a drilling vessel (13) and transferred to a drill string (7) during drill pipe connect or disconnect operations, c h a r a c t e r i z e d i n that the method comprises the steps of: a) providing a system according to claim 1 ; b) assembling the drill string (7) with a bottom hole assembly and extending the drill string (7) through the iron roughneck (1) and the power slips (2) assembly mounted on the support frame (3) below the drill floor (4) by adding in sequence drill pipes to allow the bottom hole assembly reaching a well bottom, c) extending a wellbore by rotating the drill string (7) bottom hole assembly; d) upon need of extending the drill string (7), lifting the drill string (7) to provide clearance between the bottom hole assembly and the well bottom (16b); e) wedging the drill string (7) in the power slips (2); f) heave compensating the iron roughneck (1), the power slips (2) and the wedged drill string (7) by operating the linear actuators (8; 9, 11) to at least reduce the vertical motion of the drill string (7) in relation to a wellbore; g) making-up the drill string (7) by adding one or more drill pipes to the drill string (7); h) releasing the extended drill string (7) from the power slips (2) and lowering the drill string (7) to continue the drilling; i) upon need of retracting the drill string (7) from the well, lifting the drill string (7) to provide clearance between the bottom hole assembly and the well bottom; j) wedging the drill string (7) in the power slips (2); k) heave compensating the iron roughneck (1), the power slips (2) and the wedged drill string (7) by operating the linear actuators (8; 9, 11) to at least reduce the vertical motion of the drill string (7) in relation to the wellbore; l) breaking-out the drill string (7) by removing one or more drill pipes from the drill string (7); and m) releasing the shortened drill string (7) from the power slips (2) and lifting the drill string (7) to continue the break-out.
