Computer aided design and simulation of remotely operational underwater vehicle (ROV)

Abstract

Advancements in technology in this day and age have led to the creation of robots to increase work efficiency and reduce human works. Remotely operated underwater vehicles (ROV s) are unoccupied, highly manoeuvrable tethered underwater robots that operate with response to human commands. They are made for underwater exploration and documentation, recoveries, inspections, search and rescue, trenching, cable burial and much more. This thesis discussed about the different designs of micro class Remotely-Operated Vehicle (ROV) and its simulation performance to operate in shallow water. The objectives of this study are to develop a micro class remotely operated vehicle (ROV), to propose five designs that able to fulfil its mission requirements and to analyze the performance of the candidate designs in terms of its resistance and hydrostatics using simulation software. The study is conducted based on theoretical modelling and simulation software to determine the best ROV design and its performance in a shallow water environment. All of the designs are created and fulfilled the requirements needed of a basic ROV. To summarize, the best design is selected after some data comparison generated from the analysis of several factors like pressure, velocity and drag coefficient. Some recommendation and suggestion were also made so that it can be applied in order to produce better and much more superior designs of a micro class ROV in the future.
