ABSTRACT:
A pipe joint adapted to be utilized in flow lines or well casings in which clockwise and counter-clockwise rotation is imparted to the pipe joint in order to provide for the remote subsea make and break connections between a floating vessel and a subsea well or subsea production riser base. More particularly, the invention resides in a pipe joint incorporating a locking connection enabling the pipe joint between the floating vessel and the remote subsea make and break connection to be able to transmit torque, without in any manner affecting the mechanical and pressure integrity of the pipe joint.
