Azimuth thruster for ships : Z-drive
(with twin counter-rotating propellers) VETH MOTOREN

Veth Motoren belongs worldwide to the market leaders of counter rotated rudder propellers.

Two propellers are mounted either side of the tail, each turning in opposite directions. The second propeller eliminates the rotation in the water caused by the first propeller. This improves the vessels performance up to even 15% compared to a single propeller! As the power is divided over two propellers, it is possible to put more power on smaller propeller diameters.

Another advantage of the counter rotated system is that it is extremely quiet. The reason for this is that the blade load is lower, because the input power is divided over two propellers and because of the rotational speed which is lower than with a single propeller.

This is a.o. why this system is more and more applied in passenger vessels, where a low sound level is very important. But also other types of vessels are more and more equipped with this counter rotated system, because of the high performance and the small propeller diameters.
