Veth Propulsion

Azimuth Thrusters

Veth Azimuth Thrusters are well-suited for a wide range of vessels, thanks to our flexibility and customization. Your preferences serve as the foundation, with several options, configurations, and drive lines to choose from. Our azimuth thrusters are available in either Z-drive or L-drive configurations and can be powered by any energy source. The control system for the azimuth system can be either electric or hydraulic. Additionally, the thruster units come with options for open propellers, counter-rotating propellers or nozzles.

L-drive

The L-Drive system incorporates azimuth thrusters with vertically mounted electric motors, eliminating the need for a second bevel gear in the drivetrain. This design modification leads to enhanced efficiency and reduced noise levels.

Z-drive

The Veth Z-Drive thruster offers exceptional 360-degree thrust control, providing unmatched maneuverability for a variety of vessels. Its compact, efficient design ensures enhanced fuel economy and reduced noise. Experience advanced marine propulsion with the Veth Z-Drive.

Benefits

The Z-Drive system, also known as an “azimuth thruster”, offers distinct advantages compared to other propulsion methods commonly used in marine and ship applications. Let’s explore these differences:

  • 360° full of thrust for optimal maneuverability
  • 2% more efficiency than with a conventional propeller
  • Possibility for flexible suspension (better insulation from noise and vibration)
  • Ability to change propeller without docking
  • Simple to install
  • More room for passengers/cargo due to compact construction
  • No separate gearbox needed
  • Ideally suited for Dynamic Positioning (DP)
  • Safer, through shorter emergency stopping distance and improved maneuverability

In summary, the Z-Drive system stands out due to its exceptional maneuverability, reduced complexity, noise reduction, and efficiency. However, each propulsion method has its own trade-offs, and the choice depends on the specific vessel type, operational requirements, and budget considerations.

Enhanced maneuverability

The Veth Z-Drive thruster offers unparalleled 360-degree rotation, allowing the propulsion unit to independently rotate to any angle. This capability vastly improves maneuverability, particularly in tight spaces, docking scenarios, and during precise positioning. Unlike traditional fixed propellers that require the entire vessel to turn, the Z-Drive enables vessels to change direction smoothly and efficiently, making it especially beneficial for applications requiring tight control, such as tugboats and offshore supply vessels.

Dynamic thrust vectoring

The Z-Drive’s dynamic thrust vectoring allows vessels to move forward, backward, or sideways without altering their orientation. This flexibility distinguishes the Z-Drive from conventional propellers that generate thrust along a fixed axis. The ability to change thrust direction on the fly provides superior control and adaptability, which is essential for specialized marine operations and enhances the overall versatility of the vessel in varied conditions.

Simplified drivetrain and noise reduction

With its direct motor-to-propeller connection, the Z-Drive simplifies the drivetrain by eliminating complex transmission systems and multiple gearboxes. This reduction in components lowers maintenance requirements and minimizes the risk of mechanical failures. Additionally, the vertical motor configuration of the Z-Drive significantly reduces noise and vibration, leading to improved onboard comfort. This noise reduction is particularly important for passenger vessels, research ships, and luxury yachts where crew and passenger comfort is a priority.

Efficiency and redundancy

The Veth Z-Drive’s direct connection minimizes energy losses, optimizing propulsion efficiency across various operational conditions. Vessels equipped with Z-Drives excel in station keeping and dynamic positioning, maintaining precise locations against external forces such as wind and currents. This capability is crucial for offshore platforms, research vessels, and cruise ships. Furthermore, Z-Drive systems often feature redundancy with multiple azimuth thrusters, ensuring continuous operation even in the event of a failure, which is vital for maintaining safety during critical marine operations.
