The Sub-Sea Hydrojet Rock Trenching System -
The Miah Hydrojet Underwater Rock Trencher is a high production Trenching System and a dramatic improvement over present conventional methods of excavating rock in the ocean floor for purposes of burying pipelines, submarine electrical
cables, fibre optic cables, etc. Present subsurface excavation methods in solid rock include dredging, ripping and blasting,which in many cases extensively disturb the biological environment in which they are utilized. One major objective in developing The Miah Underwater Trenching System included reducing environmental damage while subsurface work is being accomplished and to be able to restore the ocean floor to close as possible to its natural state.
