Over the last 55 years Veth Propulsion BV

has gained a reputation in the maritime

world. During this time the company has

evolved as a specialist for thrusters known

for their intelligent design, solid construction

and easy maintenance. The Veth-Z-Drive and

the Compact-Jet were developed In

Papendrecht. Various kinds of bow thrusters

– such as the well-known Veth-Jet channel

system – were also originally developed by

the Dutch company.

Apart from the thrusters Veth Propulsion BV

has a Diesel engine department which

makes it possible to supply the thrusters

together with a Diesel engine, whenever

required. Also, generator sets are built by

the same department.

The Veth-Z-Drive has proven

its reliability for many years.

With the rudder propeller,

independently designed and

manufactured, Veth Propulsion

shows that high efficiency and

excellent manoeuvrability do

not have to be a contradiction.

The Veth-Z-Drive gives full thrust

power over a circle of 360°, thus enabling a maximum

manoeuvrability of the vessel. With its wide differentiation

of types over the years, the Veth-Z-Drive offers a solution for

numerous applications. Veth Propulsion stands for innovation

in the shipping industry.

Certificates by recognized classification societies can be

obtained to accompany each installation. Veth Propulsion

maintains a comprehensive service network with excellent

service for its customers world-wide.

The Veth-Z-Drive allows a greater

flexibility than conventional drives when

planning the setup of the engine room.

Because the engine can be placed next to

the Veth-Z-Drive the space necessary is

reduced to a minimum – leaving extra

room for passengers or cargo.

For mounting inside the hull the rudder propeller is provided

with a foundation the bottom plate of which corresponds with

the line of the hull plating. This foundation can be flexibly

mounted to avoid contact with the ship’s body from the engine

to the propeller. The Veth-Z-Drive is therefore an excellent

choice where the noise level has to be kept low. One more

advantage: the unit can be mounted or dismounted

- depending on the vessel’s draught - without the ship

being dry-docked.

Apart from the standard design

Veth Propulsion BV offers a counter-

rotating system (CR). The CR

Veth-Z-Drives present a completely

new dimension of efficient

low-noise propulsion. The CR unit

combines high efficiency and small

propeller diameters with reduced noise emission.

The power is distributed over two propellers which results in a

better performance. Within the CR unit both propellers rotate in

opposite directions, so that the second propeller compensates

the whirling of the water caused by the first propeller.

As a consequence rotation loss is minimized with maximum

efficiency gained from the available power and propeller

diameters.

The optimum number of revolutions is about 20% less than a

single propeller or two rotating in the same direction. The low stress

on the propeller blades and the lessened turbulence of the water

contribute in obtaining a low vibration and a silencing effect.

The propellers of the counter-rotating Veth-Z-Drive are mounted

on opposite sides of the hydrodynamic streamlined underwater

gearbox. With this arrangement, a more solid bearing and secure

sealing system is created compared to placing the two propellers

on one side.

The Veth-Z-Drive has a built-in disc-clutch to achieve a short

construction length. This robust clutch is especially laid out for

heavy-duty operations, such as the frequent engaging and

disengaging of gears on a ferry boat.

What is not possible with conventional propulsion, poses no

problem to a Veth-Z-Drive, the height of the propeller is adjustable

thus enabling a discharged ship to manoeuvre without ballast.

This application allows an adjustment of the installation to various

heights. It is also possible to make installations, which can be

completely retracted within the ship’s construction (photos above),

an application often used for auxiliary propulsion for off-shore

installations or for mega-yachts.

Because of the ingenious universal gear coupling system,

the Veth-Z-Drive can be completely uncoupled from the driving

engine, in particular when combined with Diesel engine installations.

This makes it possible to reduce the space for the installation in spite

of the height adjustment.

The Veth-L-Drive is a good choice when

an installation is driven electrically or

hydraulically. In this case the engine is

mounted vertically but without the upper

gear-box with the free-wheel clutch.

The integrated steering wheels, however,

are the same as in the Veth-Z-Drive.

Over the years Veth Propulsion BV has

obtained special expertise with Diesel

electric installations. A frequency control

can be supplied together with the

electromotor.

Easy installation is an advantage of the

Veth-Z-Drive. It can be mounted and dismounted

outside a dry dock, depending on the vessel’s

draught. The Veth-Z-Drives are custom-made with

a foundation adapted to the hull’s construction.

The Veth-Z-Drives are very compact due to

the integration of transmission, clutch and

steering wheels into one system. Up to an input

power of 550 kW a worm gear is used for steering.

For drive power exceeding 550 kW a slewing gear

is used. Large transmissions ensure extremely

accurate steering.

Veth Propulsion BV has changed

many a vessel without it’s own

drive into an independent self-

propelling vessel by means of deck

installations, for which well

insulated, noise-absorbing casings

are used. The construction of the

shell is as compact as possible,

while the engine remains within

easy reach for service and

maintenance. Deck installations

are often furnished with a height

adjustable propeller.

The electronics department of

Veth Propulsion BV puts considerable effort

into research and development. Complete

operating systems for the Veth-Z-Drives are

designed and manufactured by the company.

Although reliability and functional

efficiency come first, good appearance

also gets attention. For the particular Veth-line

foil panels with an ergonomic control lever are

used. Veth Propulsion BV regularly develops

specific solutions for its clients, such as

synchronized control levers by means of

an electronic shaft system, or electronic

interfaces for a Dynamic Positioning System

or pilot. Veth Propulsion has also developed

an intelligent electronic pilot mainly for river

navigation.
