Abstract
A torquing tool for rotating bolts connecting a pipe flange in a subsea environment, comprising a first guide for guiding movement of the torquing along a pipe, a socket for engaging a first bolt, a shaft for transferring torque from a motor to the socket, and a first protruding member for insertion between the pipe and a second bolt of the pipe flange, to prevent the torquing tool from rotating due to counter torque created while applying torque to the first fastener. The torquing tool can further comprise a second protruding member adjacent the socket, wherein the second protruding member can be inserted between the pipe and a third bolt of the pipe flange. The torquing tool can further comprise an angled shaft for transferring torque from the motor to the socket, wherein an axis of rotation of the motor is different from an axis of rotation of the socket.
