Computer aided design and analysis of remotely operated vehicle for shallow water operation

Abstract

Remotely Operated Vehicle (ROVs) for underwater research have been under study and developed over the past few years. It is an important exploration tool especially for underwater research. As these researches have improved from time to time, it also increases the depth of underwater research exploration. Due to environment hazardous to human ability in which at high depth that pressurized divers and bring difficulty for the underwater tasks, ROVs are somehow important and needed to be improved to meets the required performance. Therefore, the objective of this project is to design and develop a micro-class remotely operated vehicle for shallow water operation mainly used for academic purposes. This paper discussed about the different designs of micro class ROY and its CFO analysis for shallow water operation. Five candidate designs of ROY with different specification and shapes are proposed for the design stage. All the designs of ROVs are needed to be analysed the performance in terms of its coefficient of drag and stability. Data are collected based on the drag coefficient and stability values calculated from formulas. The best design is selected after some data comparison generated from these two analyses. The selection criteria of the design are based on the lowest value on coefficient of drag and higher value of stability data. Some recommendation and suggestion were also made so that it can be applied in order to redesign a better and much more futuristic design of ROY for the underwater vehicle development.
