Counter rotating

Does your vessel have a shallow draft and you find low noise levels important? Then counter-rotating propellers may be of interest to you. Because the power is divided between two (smaller) propellers which rotate in opposite directions, a higher efficiency can be obtained with respect to a single propeller.

In contrast to other suppliers, Veth Propulsion offers a CR solution in which the propeller is mounted on two sides of the tail unit. This has a number of advantages:

  • The peripheral speed of the shaft seals is half that of systems with two propellers on one side, in that a shaft does not rotate inside another shaft.
  • Two separate (solid) shafts are each loaded between 45-55% of the output power
  • A durable bearing and seal is thus created, compared with two propellers on one side
  • By making use of a four-blade and a five-blade propeller, the power is distributed over nine blades
  • Less time in dock during dismantling. Seals remain in position when the propeller is removed and oil change is not necessary
  • At an equal propeller diameter, an efficiency gain of 15 to 20% is achieved compared to a single propeller

Veth Propulsion operates on a proven concept where a labyrinth is incorporated in the propeller hub. A great advantage is that the seal is well protected from fishing line or ropes.

In short, a counter-rotating Z-drive of Veth Propulsion makes the combination of high efficiency, small propeller diameters and low noise possible.
