Abstract
Over the last few decades, underwater mechanical system became a necessity for ocean research and exploration. The necessity of this type of equipment provides a new type of marine platforms in different areas of oceanographic research. Until this moment, the underwater vehicles have developed in different shapes, sizes and means of propulsion. Take into consideration these characteristics, we could determinate the type and mission of the vehicle. In this paper we investigate the problem regarding the pressure exerted of remotely operated vehicle. The remotely operated vehicle is designed in order to achieve different mission regarding the surveillance in lakes, harbors and maritime environment. This mission can take place through a remote control system placed onshore or on seaborne platforms. To improve the endurance of remotely operated vehicle, we performed a simulation study during which we compare the drag forces acts on the underwater vehicle according to its shape. Using SolidWorks program to create the body simulation vehicle and Ansys CFX to realise the simulation, this paper present the result simulated for the forward part of the vehicle.

Summary
A Remotely Operated Vehicle (ROV) provide an important role regarding collecting various oceano-graphic information, defense missions or applications, petrol, gas and different mineral exploration programs or biology studies. There was reported many studies [1]-[3] regarding the viscous fluid flow around different body shapes, for example cylinder, sphere or spheroid. For complete solution of equations, it is necessary to be solved numerically in collaboration with a computer. The coupled algebraic equations from numerical discretisation scheme are solved and determinate discrete values of velocity and pressure at mesh nodes along the surface body or in different points. All this process represented by the theoretical, numerical and computational techniques gather in Computational Fluid Dynamics (CFD) simulation. The CFD method is very usefully because help to realise an economically evaluating regarding the manoeuvrability of an underwater vehicle
