1.4. Objectives of the project
The objectives of the project are:
a. To design a low cost ROV that is lower than RM1000 using for monitoring and surveillances application.
b. To design a waterproofing body structure of with optimal size, weight and submerging depth.
c. To study the performance of the ROV in terms of stability, velocity and acceleration for monitoring application.
1.5. Scope of the project
The scopes and limitations of this project are:
a. Design and fabricate a prototype of ROV equipped with thruster to control the ROV movement.
b. This ROV only the prototypes of the real ROV, so the characteristics is lower in terms of material, power consumption and speed.
c. The platform will only consist of simple control system and basic equipment. d. The depth of testing the prototype will be less than 5 meter.
e. Controller of ROV is connect by wired to the mainland. f. The maneuverability consisted forward-reverse motion, submerge-resurface
motion and left-right rotation. g. Environment for testing selected is controllable for control environment at
laboratory pool and swimming pool.
CHAPTER 2
LITERATURE REVIEW
This chapter contains general information on ROV. The related review will focus on behavior of mechanical part while submerge body in terms of its
hydrodynamics, quantitative theories and the component related to the performance of the ROV. The facts and information were collected from reliable source and elaborated
based on understanding of the review. The information, methodologies and design from previous research will be used as references and guidelines for this project.
2.1. ROV Classification
Nowadays many ROV are being developed around the world. The main problem to build a ROV is the cost and effectiveness of the ROV itself. So, in order to
deduce this price the chosen of material type is important. Other than that, this project needs to develop new design of ROV that can fulfill important task only according to
the ROV type. From the research, the ROV is divided by several classes referring to their work ability. As NORSOK, 2003 said the classes of ROV as below [3]:
a. Class 1 – Pure Observation Pure observation vehicle are only focusing on video observation. Usually the size
was small but can fitted with lights and thrusters [3].
b. Class 2 – Observation with payload option This class of vehicles must capable to carrying additional sensors. This class
should be able to carrying at least two additional sensor without loss of original function [3].
c. Class 3 – Work Class Vehicle This vehicle is large enough to carry additional sensors and manipulators. Class 3
vehicles commonly have a multiplexing capability that allows additional sensors and tools to operate without being “hardwired” through the umbilical system.
These vehicles are larger and more powerful than Class 1 and 2 [3].
d. Class 4 – Seabed-Working Vehicles Seabed-working vehicles usually are designed for special purpose tasks. The size
must be larger than class 3. This type of ROV was able to do such tasks like cable trenching, excavation, dredging and construction works. [3].
e. Class 5 – Prototype or development vehicle This class of ROV include as prototypes.AUV is classified in this class [3].
By looking all the classes above, this project are categorized on Class 1. Besides, there are also has several factors that need to be considered while designing
an observation ROV. The factors are:
a. Material Frame Body b. Pressure Hulls
c. Buoyancy and stability d. Thruster
e. Tether
