The aim of the GATERS project is to design a new steering system (Gate Rudder), reduce the fuel consumption and emissions (CO 2 , NOX , SOX ) of ships and make ships energy efficient. In addition, the resulting design was produced and installed on designated ships to demonstrate the effectiveness of GRS in navigational trials.
There are 18 participants from different countries in the GATERS project, which is a European Union Project.
At İTÜ, which is an important stakeholder of the project, Ata Nutku carried out model measurements using the Ship Model Experiment Laboratory and Cavitation Tunnel (İTÜKAT) facilities.
Propeller open water measurement tests, cavitation tests behind the ship model, noise, pressure and wake measurements were carried out at İTÜKAT. Measurements were carried out separately for the conventional steering system (CRS) and the Gate Rudder system (GRS) and compared.
When the test results were examined, it was seen that GRS reduced the cavitation volume on the propeller blade and provided a 20 dB decrease in the noise level.
