Certified products and services for all ship propulsion needs

Baumüller offers solutions for all main and auxiliary drives in ships and, in addition to many years of experience in shipbuilding, offer support with a broad portfolio of services ranging from project planning to global service.

Baumüller has adjusted its products and had them certified for shipbuilding in particular. For example, the high-torque DST2 engines are equipped with wing mounts that make integration into the ship’s design much easier. In addition, Lloyd’s Register confirmed that the high-torque engines meet the specific requirements of shipping. DST2 ship motors are available with power ratings from 3 to 1150 kW and nominal speeds between 100 and 2000 rpm.

In addition to components and systems, the Baumüller Group provides project planning expertise and service concepts with a global service network and therefore offers a long-term partnership for the entire life cycle of your ship drives.

We have equipped ferries, inland waterway vessels, yachts, etc. with our solutions and thus offer a wealth of experience in equipping and retrofitting ships and offshore vessels with efficient ship drives.

Ship propulsion with Baumüller motors: Your sure path to increased efficiency

Switch to a hybrid or electric drive and reduce your diesel consumption by up to 25%.

A motor achieves optimum performance at a certain speed. Any deviation from this speed reduces efficiency, often by a double-digit percentage. This unnecessarily increases fuel consumption. An electric or hybrid drive uses the power differently, with the motor always running at the optimum number of revolutions no matter what. For this reason, ship propulsion with Baumüller motors is the sure path to increased efficiency for ships.

Diesel-electric drive: Greater efficiency through electrical operation with diesel generators

With a diesel-electric hybrid drive, the ship’s propellers are powered electrically by converter-fed synchronous motors which receive their energy from diesel generators. Many benefits make the combination of diesel engine and electric motor particularly attractive for the shipping industry. Along with a significant reduction in fuel consumption in moving bodies of water of up to 28%, the system also reduces noise and vibrations.

Ecological and fuel-efficient: Hybrid drive system

According to the principle of the hybrid drive system, diesel or methanol generators are cleverly combined with electric motors for maximum efficiency. Unlike drives, the generators are not exposed to power peaks and are thus always operated at optimum efficiency. This means that the generators can be smaller from the start.

The combination of generators and electric motors allows operators to save a considerable amount of fuel. Because less fuel has to be burned, the system emits fewer pollutants.

Fully electric and emission-free: E-ships with battery-powered drive

Quiet and completely free of fine particulates: These are the main advantages of a fully electric or battery-run e-motor for ships and boats. The motors are run completely with rechargeable lithium-ion batteries, without any diesel engines.

The advantages of the battery-powered ship solution from Baumüller lie, on the one hand, in the intelligent overall concept based on the company’s many years of experience in the ship propulsion sector and, on the other hand, in the highly efficient synchronous motors. The drive system thereby achieves a degree of efficiency of over 95%.

Hydrogen ship drive – emission-free opportunity for the future

Alternative ship drive with hydrogenAs specialists and pioneers in the field of alternative ship propulsion, we naturally also keep an eye on developments relating to hydrogen. This field opens up numerous opportunities for the future. Ships with fixed routes between certain destinations are particularly suitable for this alternative. It is even conceivable that ferry and offshore supply operations could be realized with hydrogen-powered ship drives in the near future. Efficient and emission-free drive technology will then also be usable with our Baumüller drive systems in the future. We keep a steady pace with the times.
