Products and services - certified for shipping

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

Baumüller has had its products specially adapted and certified for shipbuilding. For example, the DST2 high-torque motors are equipped with wing-mounts that make it much easier to integrate into the ship's design. In addition, Lloyd's Register has confirmed that the high-torque motors meet the specific requirements of shipping. The DST2 marine motors are available with outputs from 3 to 1150 kW and nominal speeds between 100 and 2000 min-1.

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


Baumüller has equipped ferries, inland waterway vessels, yachts, etc. with its solutions and thus offers a wealth of experience in the equipping or conversion of ships and offshore vessels.

Ship drives with Baumüller motors: Your secure way to increase efficiency

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

An engine achieves optimum output at a certain speed. Every deviation from this speed reduces efficiency, often in the double-digit percentage range. This results in an unnecessary increase in fuel consumption. An electric or hybrid drive employs power in a different way so the motor always runs at the optimum speed. For this reason, a ship drive with Baumüller motors is the safe way to increase efficiency for ships.

Hybrid drive system for more efficiency

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. Numerous advantages make the combination of diesel engines and electric motors particularly attractive for shipping. In addition to significantly reducing fuel consumption, by up to 28% in flowing water, noise and vibration can also be reduced.

A further advantage lies in the improvement of the overall efficiency by reducing the power output of the diesel engine, i.e. traveling in the optimum speed range. For instance, only a low power level is required for ships that need to maneuver precisely out on the open sea or that need to keep to a fixed deployment location. With a pure diesel drive the speed in these cases is massively reduced when compared to the previous, faster moving journey. This means the engine isn’t operating in its ideal efficiency range. By contrast, when an electric drive is used in these situations, the frequency converter controls the propeller speed directly via the synchronous motor, thus enabling it to run far more slowly. Since synchronous motors achieve high efficiency even at low speeds, the electric mode saves fuel.

Perfect combination – E-ships with hybrid drive systems

With a hybrid drive, the ship’s propellers are powered electrically by converter-fed synchronous motors which receive their energy from battery and diesel generators, e.g. LNG, diesel, fuel cells, etc. Numerous advantages make the combination of diesel and electric motors particularly attractive for shipping. Along with a significant reduction in fuel consumption in moving bodies of water, this system also reduces noise and vibrations by up to 28 percent.

Optimum efficiency – e-ships with parallel hybrid drive

In a parallel hybrid ship’s drive the diesel engine and electric motor are connected in series. The output and the torque are added. The electric motor can be connected and disconnected. The combustion engine is kept at a very good efficiency. The actuator absorbs the load peaks and also generates energy.

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

Quiet and completely free of fine dust, these are the key advantages of a fully electric or battery-powered electric motor for ships and boats. The motors are operated entirely without diesel engines, using lithium-ion batteries.

In collaboration with companies such as battery manufacturers, the system engineering experts from Baumüller create complete solutions for drive and automation systems and fit out ships using in-house torque motors, converters and control units, among other devices. The Baumüller complete solution includes electric motors, scalable lithium-ion batteries with energy management systems, control cabinets, thruster and propeller control units. The integrated automation systems, which are linked to all other subsystems via CAN bus and Ethercat, serve to control and monitor on-board machines and auxiliary systems. Also, the battery-powered electric drive system is supplemented by two diesel emergency units. These are legally required safety drives which ensure maneuverability even when the battery is empty and are therefore redundantly designed.

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

Over 80 ships and boats successfully electrified

We have experience with hybrid cargo ships for inland waterways and coastal use, hybrid working vessels as well as hybrid and electric ferries.

We are the experts in the complete drive system: From control unit to battery management. Past implementations have included e.g. hybrid cargo ships for inland waterways and coastal applications, hybrid work ships, as well as hybrid and electrical ferries. Whether original equipment or a remotorization – our marine drives impress with their lower environmental impact, improved maneuverability and space-saving installation compared to classic diesel drives.
