STADT AS develops integrated electric propulsion systems and AC drives for marine vessels. The company’s latest product is the STADT Lean Drive innovative electric propulsion system
In December 2015, STADT celebrated its 30th anniversary in the maritime technology sector, and moved to its modern maritime centre in Gjerdsvik, Norway.
Approximately 31 ships in different categories were using the STADT Lean Drive technology by the end of 2015.
Marine drives for electric propulsion systems
The STADT Lean Drive electric propulsion system is the company’s fifth generation of its electric propulsion systems for ships. Available in models from 100kW to 80MW, the system features low and medium voltages up to 15kV.
The system minimises fuel consumption and reduces CO₂, SOx, and NOx pollution. It also performs silently without any electric disturbances.
STADT Lean Drive for propulsion systems
The STADT Lean Drive electric propulsion system is the product of four years of research and development.
Company director Hallvard Slettevoll describes the new system as a ‘breakthrough in technology’, because it combines the unique features of pure sinusoidal electric power for the main switchboard, electric motors and other electric consumers while minimising space occupation and cost.
Sinusoidal waveform on current and voltage protects sensitive electronic equipment from interference by inverter drives, such as echo sounders, radars, and seismic research instrumentation. It also minimises noise produced by electric motors and drives and guarantees protection from bearing damages.
This gives STADT’s system an edge over other well-known electric drives suppliers, who have supplied systems with a high degree of electric noise / pollution in their main switchboard grids, as well as EMI (EMC) to the surroundings.
Silent and space-saving electric propulsion system
Since large propulsion transformers are not required, the STADT Lean Drive propulsion system saves space and achieves a total harmonic distortion (THD) level of less than 2%.
Sustainable and robust technology
STADT Lean Drive is extremely reliable and offers a long lifespan of 30 years or more.
This durability is achieved by using fewer components in the drive system, as well as different parallel technologies that are redundant to each other.
System integration
STADT has extensive experience in system design and integration for different kinds of ship projects.
Our broad range of system components, in different types of technologies, enables us to design optimum solutions for each individual project.
System Integration
STADT is a supplier of integrated electric propulsion systems, which the company refers to as LEAN Propulsion Design.
Motors
We offer custom-made asynchronous motors for any application in the shipping sector.
Switchboard
STADT designs and delivers custom-made, state-of-the-art, marine switchboards tailored according to customer specification.
Power Management System
The STADT PMS features functions required for controlling power generation and distribution on board a vessel, including generators, synchronisers, governors and main switchboard breakers.
Advanced Ship Propulsion Systems
A reliable propulsion system is crucial for ship safety. It enables the vessel to complete operations around the world and maintain its sailing schedule.
VariAC Lean Propulsion for Vessels
STADT Lean Drive technology is available in many options to control the propeller power by regulating both the pitch and the RPM of the propeller.
