Subsea flange tool

A method of applying torque to a fastener of a flange connection in a subsea environment, the method comprising the steps of:

• providing a torqueing tool comprising:
• a first guide surface;
• a socket;
• and
• a first protruding member adjacent to the socket,
• positioning the first guide surface of the torqueing tool along a surface of a pipe;
• moving the torqueing tool along the surface of the pipe;
• mating the socket with a first fastener of the flange connection;
• inserting the first protruding member between a second fastener and the pipe to secure the torqueing tool in position and prevent rotation thereof;
• and
• actuating a motor to rotate the first fastener.

A torqueing tool for rotating bolts connecting a pipe flange in a subsea environment, the torqueing tool comprising:

• a first guiding surface for guiding movement of the torqueing tool along a pipe;
• a socket configured to engage a first bolt;
• a shaft for transferring torque from a motor to the socket;
• and
• a first protruding member adjacent the socket, wherein the first protruding member is configured such that when the first protruding member inserted between the pipe and a second bolt of the pipe flange the protruding member prevents rotation of the subsea tool, and wherein the socket and the first protruding member are even along a length of the torqueing tool.
