Abstract
One construction method for burying offshore pipelines utilizes a segmented excavation shield for forming a trench in the seafloor. The present invention provides a propulsion method for advancing the shield which eliminates the need to pull the shield. This is done by advancing skin plates which are attached to the shield, then advancing the shield by transmitting soil reaction through the skin plates, which remain stationary, to the shield.
