Subsea casing hanger running tool with anti-rotation feature and method for rotating casing into complex and deviated wellbores

A system for running casing, comprising:

• a tool string;
• a running tool, coupled to the tool string;
• and
• a casing torque tool, coupled to the running tool, and configured to releasably engage at least a portion of a casing string, the casing torque tool comprising:
• a translatable cam within a casing torque tool bore, the cam having a recess formed in an outer diameter and a notch formed in an inner diameter, the recess having a smaller recess diameter than a planar section of the outer diameter;
• a tool key adapted to move radially with respect to the casing torque tool bore, the tool key bearing against at least a portion of the translatable cam and, in response to movement of the translatable cam, transitioning between a retracted position, wherein at least a portion of the tool key is positioned within the recess, and an extended position, position wherein at least a portion of the tool key extends radially outward beyond a casing torque tool outer diameter;
• and
• a pin adapted to move radially with respect to the casing torque tool bore, the pin translating into the casing torque tool bore in response to being at least partially aligned with the recess.
