During the project execution of design and optimization the Remotely Operated Vehicle (ROV) research on its propulsion has been carried out. The entire project was supported by CFD and FEM calculations, which taking into account the characteristics of underwater vehicle. One of the tasks was to optimize the semi-open duct for horizontal propellers, which provided propulsion and controllability in horizontal plane. In order to create a measurable model of this task it was necessary to analyze numerical methodology of propeller design, propellerwith nozzle and contrarotating propellers. It was confronted with theoretical solutions which include running of analyzed propeller near underwater vehicle. Also a preliminary qualitative analysis of simplified system which included contrarotating propellers and semi-open duct were carried out. It enabled to proceed with design decision about ROVs duct form. Rapid prototyping SLS (Selective Laser Sintering)method was used to fabrication physical model of the propeller. As a consequence of this, it was necessary to verify the FEM model of the propeller, which based on the load obtained from the CFD model. The publication contains characteristic of ROV, theoretical base of propeller design for analyzed cases and results of CFD and FEM simulation.
