Abstract: In present computer based simulations play a huge role in understanding, analyzing and solving real world problems. There is a vast area of study related to the eld. One such application in natural phenomena is ocean simulations. The maritime studies are carried out with ocean behaviors, ship movements, tug boat operation and etc. The area of the this study is on ship generated waves. Simulations can be categorized as real time and non-real time methods. Non real time methods can focus on higher quality than the running time. But in real time simulations it needs to focus on a particular time limit. All the processes are needed to be carried out within a time frame. When considering the movement of vessels, there are two major areas to be concerned. One is the study on the behavior of ship due to the ocean surface. And the other one is the e ect on ocean surface. Ship waves are generated because of the e ect on ocean surface due to the moving vessels. The typical pattern of a ship generated wave is known as Kelvin Ship Wave pattern. The discussed methodology through the research is a geometrical approach to give a solution to the Kelvin Wave problem. The kelvin wave pattern is consisted with two major sub patterns such that transverse wave and the divergent wave. The transverse waves move along the sailing line and the divergent waves move away from the sailing line. The wave pattern represents a V shape. The shape varies with the external factors. The study is carried out to the vessels which are moving on Deep Ocean with a Froude number less than 1.The objective of the study is to come up with a real time simulation module to generate ocean going vessels. Keywords: ship waves, hydrodynamics, kelvin ship wave, Cartesian grid, Computer Sim- ulation
