Research and Development a Remotely Operated Underwater Vehicle

This paper presents a research and development of a Removed Operated Underwater Vehicles (ROV). It is torpedo-shaped ROV with 3.2 m in length, 0.3 m in diameter. The main hull of the ROV is made by steel and aluminum. In this design, the ROV is driven by flexible steering system. In horizontal direction, the ROV is driven by a couple of blade ruder. In vertical direction, the ROV is driven by a couple of thrusters. For increasing the ROV stability, three fixed fins are designed with hydro dynamic profiles and located on the back and at the rear of the ROV. Resistance of the ROV has been estimated by CFD method before selecting its main propulsive propeller and selection of the main electrical motor. For communication and controlling, the ROV uses both wire and wireless technologies. The ROV pulls a float when it moving underwater. Communication between the ROV and the float is wire communication. Communication from the float to a control station on land is wireless.
