What is Schottel propulsion?

What is Schottel propulsion?

Schottel is a manufacturer of propulsion and steering systems for ships and offshore applications. Today the company develops and manufactures azimuth propulsion, maneuvering and steering systems.

What is SRP propulsion?

The main distinguishing feature of the SRP is the combination of propulsion unit and azimuth steering. This makes a rudder superfluous and converts engine power into maximum thrust. The 360-degree steering of the rudder propeller means that the full propulsion power is available for manoeuvring.

What is an Azipod propulsion system?

Azipod® is a gearless 360° steerable propulsion system, where the electric motor is located in a submerged pod outside the ship hull. By utilizing the Azipod® system’s maneuverability, marine vessels can direct thrust in any direction with incredible precision, saving time and fuel.

What is a Becker rudder?

A Flap Rudder (aka a “Becker rudder”) is a specific type of multi-section rudder used on boats and ships. The hinged aft section gives the rudder an extra control surface, enhancing its efficiency. According to Kongsberg “A flap rudder produces more side force than a classic rudder of equivalent size.

How does Voith Schneider propeller work?

Each blade can rotate itself around a vertical axis. The internal gear changes the angle of attack of the blades in sync with the rotation of the plate, so that each blade can provide thrust in any direction, very similar to the collective and cyclic of helicopter flight controls.

What is the difference between azimuth and Azipod?

In the conventional azimuth thrusters such as Z-drive and L-drive thrusters, the propeller is driven by an electric motor or a diesel engine inside the ship’s hull. In the Azipod unit, the electric motor is mounted inside the propulsion unit and the propeller is connected directly to the motor shaft.

What is azimuth stern drive?

Azimuth, more commonly known as ASD (Azimuth Stern Drive), equipped with two stern engines capable of generating a 360°, all directional propulsion force. This enables them to work successfully on the vessel’s stern and shoulder. Also, when required, they can operate in ‘Bow-to-bow’ mode.

How does Becker rudder work?

The Becker-type rudder has a moving flap on the trailing edge. When the rudder moves, a mechanical linkage diverts the flap to a higher angle to maximise the sideways thrust. High-lift flap rudders are specified for vessels which require better manoeuvrability than a conventional rudder, can provide.

How do you use Becker rudder?

How to Use a Becker Rudder

1. Keep angles below 35 degrees when operating at full speed, or accelerating to the point of full speed, for maximum lateral force.
2. Use angles of 45 degrees or greater when maneuvering a Becker rudder on a ship while still in a harbor during the process of berthing or unberthing.

What is a Voith drive?

The Voith Schneider Propeller (VSP) is a specialized marine propulsion system (MPS) manufactured by the Voith Group based on a cyclorotor design. It is highly maneuverable, being able to change the direction of its thrust almost instantaneously. It is widely used on tugs and ferries.

Why are Azipods more efficient?

The pod’s propeller usually faces forward because in this pulling (or tractor) configuration the propeller is more efficient due to operation in undisturbed flow. Because it can rotate around its mount axis, the pod can apply its thrust in any direction.

How does azimuth stern drive work?

Azimuth, more commonly known as ASD (Azimuth Stern Drive), equipped with two stern engines capable of generating a 360°, all directional propulsion force. ASD tugs normally have a towing winch forward and, when commercially required, a towing winch and/or towing hook aft.

Do you need bio oils for Schottel transversethruster?

There is no need to use bio oils (EAL). This installation variant can also be supplied in an elastic version, which ensures a further reduction in noise and vibration levels during operation while enhancing comfort on board.

What can Schottel automation systems be used for?

SCHOTTEL Automation Systems and Marine Services can be used to exploit the further potential of individual vessels or even an entire fleet.

Which is the best propulsion unit for a tug?

Tugs play a key role in the efficient handling of cargo in ports. Their tasks are manifold: from ship handling and escort to salvage operations and berthing manoeuvres. Tugs need to be both powerful and manoeuvrable. These are two features that distinguish the SCHOTTEL RudderPropeller and make it the world’s leading propulsion unit for tugs.
