Starting point

The MS Waldstätter (built in 1998) has been powered by a conventional, two-engine diesel system since 2008. In order to make it fit for future use, the propulsion system was updated to make it state-of-the-art.

Goals

In the future it will become increasingly important to reduce fuel consumption and therefore carbon emissions. The system should also be able to handle conversion to a genuinely sustainable energy supply in the future. The exhaust gas system has also been updated and now complies with the Euronorm Stage-V standard.

The project was launched in February 2018, and the first systems were dismantled in December 2018. The assembly of the new drive units began in January 2019. The work was completed with various test runs at the end of April 2019.

Challenges

The project covered the following points:

  • Replacement of the propulsion system, incl. gears, thrust bearings and starter batteries.
  • Adjustment of the exhaust system (silencer, insulation)
  • New generator set
  • Conversion of the control panel incl. associated devices

It’s exciting to see how efficient the new hybrid drive system is compared to the conventional one.
