Abstract
Today, the Propulsion System installed in vessels has become diversified as the military science and technology has become highly modernized including automatization of the battlefront at sea, the multipurposing the mission that is given to the naval vessels, and the optimization of survivability in order to continue long-term combat capability, etc.

Particularly, in case of the newest vessels which have the role of dealing with different missions, relating to threats from submarines, ships and aircraft. To achieve an efficient mission capability, it has become necessary to deliver a superior performance characteristic for the propulsion system.

At this moment, the mechanical propulsion system has been changed into either hybrid propulsion system or an electrical propulsion system from. Therefore, the control and monitoring of the each propulsion equipment system has become complicated and as a result of that, the role of PSI (Propulsion System Integration) has become very important.

It is hard to perform PSI in an independent way objectively because PSI performances are carried out in a critical design phase and furthermore, a PSI agency signs a contract with a shipyard. Thus, in this paper, two solutions are suggested to solve the above mentioned issues.

Establishing a professional PSI technical institute in order to perform PSI in a fair and independent way

Performing PSI from the schematic design phase and following its execution procedures

Describing the above two suggestions in detail, and achieving PSI according to the preliminary design, the researcher has defined the output that can be obtained through the preliminary design of PSI, and multi-party collaboration among PSI professional institutes, shipyards, the navy and defense acquisition program administration.

Furthermore, the simulation program has been developed to verify the process of propulsion system changeover. With this program, the research has analyzed data of axial load and rotation speed, and also it has verified the proposed propulsion system changeover.
