Product catalog summary

Introduction to STADT and Its Founding:
STADT was founded by Hallvard L. Slettevoll in 1986 in Gjerdsvika, Norway, leveraging his experience from Philips in frequency converters. The company is strategically located in a maritime cluster, focusing on developing power inverters for ship applications.

Development and Innovation:
In 1997, STADT launched a modern inverter series with a compact design due to direct water cooling. The first delivery was to the Norwegian coastguard, marking a significant breakthrough. The inverters, with power up to 3500 kW 690 V, were used in diesel-electric propulsion for ships and offshore applications. In 2001, the water-cooled IGBT-converter business was sold to ABB.

STADT STASCHO Technology:
Post-2001, STADT developed the 5th generation AC drives, the STADT STASCHO, patented in 2008. This technology offers significant advantages over traditional PWM technology, including reduced electric disturbances and system losses of only 6%. It provides sinusoidal voltage and current, reducing harmonic disturbances and improving efficiency.

Environmental and Operational Benefits:
The STADT STASCHO technology reduces fuel consumption by up to 70%, lowers emissions (NOx, SOx, CO2), and minimizes maintenance needs. It is a highly reliable and compact system with an estimated lifetime of over 25 years, offering high maneuverability when combined with CP propellers.

Product and Service Offerings:
STADT provides engineering, manufacturing, commissioning, and global services. Their solutions include LNG-electric, diesel-electric, and hybrid-electric systems. The STADT STASCHO can deliver up to 100 MW at voltages up to 15 kV.

The picture shows founder, Hallvard L. Slettevoll, back in 1986 when he started the business in Gjerdsvika. Four years ahead of this, he worked as a engineer for Philips. He got the idea to start up a business based on the research work carried out by Philips in the field of frequency converters. With the Philips knowhow and some new ideas he returned to his home village, and founded the STADT company. This was a breakthrough, and the business improved rapidly. The main business area for the new inverters, made in powers up to 3500 kW 690 V, was for diesel-electric main propulsion of ships, as...
