Owner/Manager: Transatlantic RAB Sweden
Vessel type: Ro-Ro
Main engine: 2 x MaK 6M552C, 9000 kW
Exhaust gas boiler: 2 x HTI, 800 kW each

Installation year/s: 1999
Infrasound generators: 2 x APM100, 1 x APM10

The first two infrasound generators, installed in 1999 keep the catalysts and economizers after two main engines clean. A third infrasound generator, installed in 2004 is keeping the catalyst after one of the auxiliary engines clean.

Some of the benefits that the Infrasound Cleaning System has brought to the customer are:

  • Eliminated need of additional cleaning methods
  • Reduced steam consumption
  • Increased lifetime of catalysts and economizers
  • Reduced maintenance costs of economizer and catalyst

The Chief Engineer on M/V Ortviken, October 25th 2004 has provided the following information:

For the catalysts the infrasound generators have proven to be so effective that no other soot cleaning devices need to be used. The steam soot blowers are in fact permanently shut down.
