Abstract
Present embodiments relate to a riser bolt torque device that is configured to couple a first riser joint to a second riser joint to form a riser of a subsea drilling system. The riser bolt torque device includes a first arm and a second arm, multiple torque tools supported on the first arm and the second arm, and one or more actuators configured to drive the first arm and the second arm to pivot relative to one another from an open configuration to a closed configuration to enable alignment between the multiple torque tools and a flange of the first riser joint.
Claims16
A riser bolt torque device configured to couple a first riser joint to a second riser joint to form a riser of a subsea drilling system, the riser bolt torque device comprising:
- a first arm having an inner curved surface and a second arm having an inner curved surface, wherein the first arm and the second arm are pivotably coupled to each other about a same pivot point;
- a plurality of torque tools supported on the first arm and the second arm;
- and
- one or more actuators configured to drive the first arm and the second arm to pivot relative to one another from an open configuration to a closed configuration to enable alignment between the plurality of torque tools and a flange of the first riser joint, wherein one or more grooves are formed radially along the inner curved surfaces of each of the first and second arms to accommodate one or more auxiliary lines when in the closed configuration.
A riser bolt torque system configured to couple a first riser joint to a second riser joint to form a riser of a subsea drilling system, the riser bolt torque system comprising:
- a riser bolt torque device, comprising:
- a first arm and a second arm each having inner curved surfaces and one or more grooves formed radially along the inner curved surfaces of each of the first and second arms to accommodate one or more auxiliary lines when in a closed configuration, wherein the first arm and the second arm are pivotably coupled to each other about a same pivot point;
- a plurality of torque tools supported on the first arm and the second arm;
- and one or more actuators;
- and
- a controller configured to:
- instruct the one or more actuators to drive the first arm and the second arm from an open configuration to the closed configuration to enable alignment between the plurality of torque tools and a flange of the first riser joint, wherein the first arm and the second arm form an annular ring that is configured to surround the first riser joint in the closed configuration;
- and
- instruct the plurality of torque tools to apply torque to one or more bolts to couple the first riser joint to the second riser joint to form the riser of the subsea drilling system.
