Abstract
The invention is for a submarine pipe laying device which is mounted to pt on two axes on a pipeline laying vessel and which allows for mating and deploying sections of the pipe in a string. A cradle is used to hold a length of pipe and a clamp holds the end of the last deployed section of pipe while a torque box unit attaches and allows each successive length of pipe to be lowered into the water. The dual axis pivoting allows the vessel to be moored in any position and is not required to be aligned with the pipeline being layed.
