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.
Claims4
A method of operating a riser bolt torque system, the method comprising:
- adjusting a riser bolt torque device from a radially-offset position to a centered position relative to a first riser joint;
- adjusting the riser bolt torque device from an open configuration to a closed configuration by pivoting a first arm and a second arm of the riser bolt torque device toward one another about a same pivot point;
- adjusting a plurality of torque tools of the riser bolt torque device to engage a plurality of bolts that extend through the first riser joint;
- and
- operating the plurality of torque tools to apply torque to the plurality of bolts to couple the first riser joint to a second riser joint to extend a riser of a subsea drilling system.
