This e-book specializes in the hot result of the examine venture funded by way of a Grant-in-Aid for clinical learn (S) of the Japan Society for the advertising of technology (No. 23226017) from FY 2011 to FY 2015 on an independent spilled oil and gasoline monitoring buoy procedure and its functions to marine catastrophe prevention platforms from a systematic standpoint. This e-book spotlights learn on marine catastrophe prevention platforms concerning incidents regarding oil tankers and offshore structures, forthcoming those difficulties from new clinical and technological views. the main crucial point of this publication is the improvement of a deep-sea underwater robotic for real-time tracking of blowout habit of oil and fuel from the seabed and of a brand new kind of self sufficient floor motor vehicle for real-time monitoring and tracking of oil spill unfold and float at the sea floor utilizing an oil sensor. The undertaking of those robots is to supply the simulation versions for fuel and oil blowouts or spilled oil drifting at the sea floor with measured facts for extra precision of predictions of oil and fuel habit.

4 Tracking The robot absolute position is needed for several purposes, notably for robot guidance and water survey. Robot control relies on underwater position to determine the direction and distance in which the robot should go. The concentration of oil substances will be assigned to their absolute position. Then it is possible to know the distribution of oil in the area and use that to develop a strategy to track the oil slick or find the blowout gas source. SOTAB-I is fitted with a GPS receiver that can output the robot’s absolute position when it is on the sea surface.

4 Definition of parameters of the equation of motion 41 Symbols (X, Y, Z) (UX , UY , UZ ) (WX , WY , WZ ) (! X , ! Y , ! / Derivative with respect to time cylinder. Let us define (XE,i YE,i ZE,i ) and (XE,SOTAB YE,SOTAB ZE,SOTAB ) as the target point and the position of SOTAB-I, respectively, in the Earth-fixed coordinate. If we define (Xp , Yp , Zp ) as the offset of the present position from the target point in the body-fixed coordinate, (Xp , Yp , Zp ) can be obtained as follows. 5) A pair of wing angles is obtained using the PID control algorithm based on the offset components Xp and Yp .

10 Diagram of operation during at-sea experiments 32 M. Choyekh et al. 1 Ship Computer On board the ship, a portable computer running on Windows 7 operating system is employed. The integrated development environment (IDE) is Borland CCC6. The GUI and the TrackLink will be executed. TrackLink is the software that comes with the USBL product. TrackLink is used to determine the robot position and to manage the underwater communication. It connects to the external devices through an RS-232 serial interface (Fig.
