SIMPLY THE BEST SOLUTION FOR FUTURE SHIPS
2 STADT - AWARDED TECHNOLOGY LEADER 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 delivery went to the Norwegian coastguard K/V Tromsø. 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 well as offshore applications on oil rigs and for industrial use. Companies like TFDS -Hurtigruten, Geo Shipping, PGS, Sanco Shipping, Aker, Statoil, Hydro, BP and Bayer AG became regular customers. In 2001 the water cooled STADT IGBT-converter business, based on PWM technology, was sold to ABB, which incorporated them into their marine product range. Since 2001 STADT has been working with development of the 5. generation AC drives, the STADT Lean Drives. This new no loss technology is based on sinus control and developed upon a lean perspective. It was patented in 2008, and launched to the first ship applications the same year. The new drive technology has been awarded several times for its unique characteristics, and many ships are now sailing with the Lean Drive technology all over the world. Long experience from development of motordrives has resulted in the patented STADT technology. This has huge advantages compared to traditional PWM-technology, since it is free from electric disturbances. The STADT Lean Drive is also a very efficient power drive system, bringing reliability up to a new standard.

8 WHY WE USE CPP - CONTROLLABLE PITCH PROPELLER, AND NOT FP THE PATENTED STADT LEAN DRIVE COMBINES PITCH AND RPM-CONTROL Significantly improved overall efficiency at varying load and/or varying speed conditions Better manoeuvrability (acceleration, breaking, crash stop)- Better performance at reversing and in DP. Better operational conditions for gear, shaft, and bearings, especially at low speed Forgiving for design errors Each blade may be changed independently if damaged, at sea Future-proof with regard to changes of use of the vessel, slow steaming, extensions, etc. Possibility for full feathering position, which is saving fuel when only running one propeller
