Abstract:
An improved multi-bolt and nut torque wrench for installing and removing bolts or nuts from flanged joints or the like which includes a plurality of torque stations having a plurality of high torque wrenches for engaging the heads of the bolts or nuts during a high torque phase of removal or installation; a plurality of low-torque motors operatively engaged with the wrenches for rotating the bolts or nuts during the low torque phase of removal or installation; a source of hydraulic fluid for driving the low-torque motors during the low-torque phase, and driving the high-torque wrenches during the high torque phase; and a mechanism for switching between the two phases depending on the torque needed.

Claim (Index 32):
A method of breaking out a riser string, comprising the following steps:\n (a) providing a plurality of torque stations, each torque station including:\n (i) a wrench body that includes first and second end portions, and a drive head on the first end portion of the body; \n (ii) a torque wrench operatively connected to the drive head for turning the drive head a driving rotational speed; \n (iii) a horizontal positioning mechanism for moving the drive head in a generally horizontal direction; and \n (iv) a vertical positioning mechanism for moving the drive head in a generally vertical direction, wherein when the drive head is engaged with a threaded bolt or nut member, the vertical positioning mechanism can vertically position the drive head independent from operation of the torque wrench, and wherein the horizontal positioning mechanism moves the drive head along a generally horizontally extending line; \n (b) providing a controller that controls the plurality of torque stations, including the torque wrenches, the horizontal positioning mechanisms, and the vertical positioning mechanisms; (c) supporting a riser string on a drilling rig or platform, the riser string including a plurality of joints of riser sections, wherein the riser joint sections are threadably connected together with a plurality of riser threaded bolt members; (d) the controller causing the plurality of drive heads to each engage one of the plurality of riser threaded bolt members on one of the plurality of riser joint sections; (e) the controller causing each of the drive heads to break out their respectively engaged riser threaded bolt member; (f) causing the plurality of drive heads to spin up their respectively engaged riser threaded bolt members, wherein, during the spin up process, the respective torque wrenches turning their respective drive heads; (g) the controller causing the plurality of drive heads to disengage the plurality of riser threaded bolt members, and providing clearance for another one of the plurality of riser joint sections to be broken out of the riser string; (h) removing and retrieving the riser joint section of the riser string; and (i) raising the riser string a distance so that another one of the plurality of riser joint sections can be broken out, removed, and retrieved; and wherein the controller automatically controls the plurality of torque stations.
