The goal of this work is to develop an efficient vessel stabilization system that utilizes a gyroscopic device to reduce the ship's roll caused by waves or lateral forces. The requirements for the stabilizer are that the amplitude of the roll angle under external excitation is reduced by at least 50 %, and that the number of roll oscillations from a specific tilt angle to an amplitude of 2 degrees is also reduced by 50 %. The concept of the project encompasses the design process, dynamic model development, simulation, production, assembly, programming, and testing of the gyroscopic stabilizer installed in a ship model. The introduction will provide the theoretical foundations of ship seakeeping and the principles of the gyroscopic stabilization, followed by the development of the dynamic model for system simulation, and the simulation will be conducted using Matlab software. After that, the components used in the stabilizer system will be described. Next, the design process for the model parts in SolidWorks will be presented step by step. The model fabrication will be detailed in a separate chapter, as will the testing of the completed model and the final comparison with the simulations.
