Prediction of propeller forces during ship maneuvering

Tomasz Abramowski
A method is proposed for the determination of propeller forces during ship maneuvering. Artificial neural networks were applied to the performance prediction of a propeller working under such conditions as braking, stopping and running astern. Furthermore, an effect of oblique motion of a maneuvering ship, is studied by means of computational fluid dynamics methods. Wake distributions in the propeller plane are presented when the drift angle gets higher. A simple application example of the discussed methods is presented for a real case of a maneuvering ship.
