The Norwegian company STADT has for many years been a frontrunner in development of electric propulsion for ships. The company’s latest generation solution, STADT Lean Propulsion ® have already been awarded for its revolutionary design with a set uniqueness’s : very high efficiency, STEALTH-silence, low signature, reduced weight, high reliability and low maintenance cost for shipowners.
To meet new requirements STADT now release a new feature in
Lean Propulsion , The VariAC ™ .
This option give customers the possibility to take increased effect / advantage of variable speed from Diesel or LNG-gensets fitted with variable speed-control.
STADT VariAC ™ operates on an AC grid with variable frequency in a range of 45-65 Hz, and will give ship operators more efficient and precise control of power-load and ship-speed via a seamless regulation of propeller speed (RPM) and Pitch in three different power-modes – Low, Medium and High-power – very scalable for propulsion systems in the range 1 to more than 50 MW pr propeller.
The first version of STADT VariAC ™ is designed and developed in cooperation with PON –
Caterpillar, with the utilization of Caterpillars and MaK products.
By the new VariAC™ feature, STADT have increased the Lean Propulsion® system benefits in a set areas, and will secure
- Overall lower fuel consumption and emission, especially on low and medium power
- Lower noise level during operation
- Less Lube oil consumption
- Less wear and tear on genset with lower maintenance cost
- Higher Propulsion efficiency
“In cooperation with leading LNG and Diesel-generator vendors, we see that we with the STADT VariAC™ can utilize latest generation motor-technology to even lower operational cost for our customers” says Hallvard Slettevoll, ceo at STADT AS.
