| dc.description.abstract | Sub-sea ground is digged by a trenching machine before cables or pipelines are laid on the sea bed. There are three methods for trenching the sea bed | - |
| dc.description.abstract | pump pressure, water flow rate, number of passes, stand-off distance, nozzle type, soil shear strength etc. In this research, basic concept design of water jet trenching machine is proposed. A new type of ejector, so called hood type ejector is invented. In the concept, the distance between nozzles and ground is deceased. This concept design will improve trenching affectivity. Employing such design concept a prototype model is published. | - |
| dc.description.abstract | mechanical cutter method, plough method and water jetting method. Water jet method is the most widely used over the world. Water jet depends on various parameters | - |
