ROV trencher is a kind of ROV which trench the sea floor using specifically designed water jetting tool. For this trencher, maximization of trenching depth and trenching speed (or progress rate) are two of key performance, both of which directly depend on the proper design of jetting arm system. In this paper, we discuss some of optimal design considerations for water jetting arm system through laboratory...
ROV trencher is a kind of heavy-duty work class ROV with high pressure water jetting tools cutting the sea floor and burying the cable. This ROV is mostly used for PLIB (post lay inspection and burial) operation. For a ROV trencher, usually there is a pair of jetting legs mounted at the bottom and stowed in a horizontal position in its rest mode. While burying cable in the sea floor, they are folded...
