Conceptual Design of Remotely Operated Underwater Vehicle

Abstract

Research in the underwater of the sea is a very interesting field. However, due to the difficulties and dangerous condition, human activities under the sea water are limited. Thus, a dedicated tool or device such as a Remotely Operated Underwater Vehicle (ROV) is required in helping human to perform these research activities. This paper presents design and construction of ROV, which differ depending on its applications. Some of the ROV’s classifications include micro, mini, general, light work class, heavy work class and burial ROV. Therefore, it is essential to identify the design concept and the classification of a new proposed ROV for underwater application. Several main sub-modules need to be considered during the development of ROV, which include structured/ frame and fitting, control unit/CPU, monitoring system (camera), buoyancy and propulsion system. Each module needs to be properly designed so that the ROV can work as planned. This paper presents a concept design of the ROV including its specifications, before the main development and fabrication work can be carried out. The proposed ROV is designed so that it can operate with low resistance. In order to visualize this concept, 3D CAD models had been generated. An external flow analysis of the ROV had also been performed. Keywords : Underwater; External Flow; Underwater Robotics
