Abstract
A device for cutting and plugging underwater pipes, the device includes a frame with one or more clamps for securing the device to the pipe. Attached to the frame is an arm having a first end and a second end. The first end is attached to an actuation element that in combination with a support bar can pivot and extend the arm. A motor is attached to the second end of the arm. A saw blade and pipe plug is concentrically mounted to the motor. The motor powers the saw blade to cut the pipe transversely. The arm then positions the pipe plug concentric with the cut pipe, and in combination with rotation of the motor, plugs the cut pipe with the pipe plug.
