SIMPLY THE BEST SOLUTION FOR FUTURE SHIPS

The STADT Group was founded by Hallvard L. Slettevoll in 1985. In December 2015 - the 30th anniversary was celebrated. At the same time the group moved in to the new and modern STADT Maritime Center in Gjerdsvika. With a location in the middle of the maritime cluster on the west coast of Norway, the aim has always been to develop power inverters for ship applications. In 1997, after several years of intensive developments, an innovative and modern inverter series was launched. A major advantage of these inverters, was the very compact design due to direct water cooling. The first STADT...

STADT LEAN PROPULSION DESIGN - PATENTED LEAN TECHNOLOGY Superior technology with Stealth performance. The STADT NO-LOSS drive provides sinusoidal voltage and current to the electric motor and back to the main switchboard. This gives very low harmonic disturbances in main switchboard and AC motor. A SUSTAINABLE LEAN SOLUTION, BECAUSE: • • • • • • • • • Reduced fuel consumption, by up to 60 % Reduced electric losses in systems, only 6 % Reduced NOx, SOx and CO2 emission Reduced maintenance and high redundancy MTBF: 7 Years, MTTR: 1 Hours Reduced noise and no EMC – a Stealth solution Highly...
