PrimeServ to Retrofit SCR System for German Cruise Ship

MAN Energy Solutions after-sales division in Augsburg in Germany MAN PrimeServ Augsburg has developed an SCR solution that will be retrofitted aboard the MS a‘Amadeaa’, a cruise ship chartered by PHOENIX Reisen GmbH Bonn and managed by BSM Cruise Services. Also known as a Das Traumschiff, the Amadea is well-known in Germany as the main filming set for a very popular television series. The retrofit devised by MAN PrimeServ Augsburg calls for the integration of two of MAN’s SCR systems, one each into both of the Amadea’s four-stroke MAN 7L58/64 propulsion-engines, to ensure maximum performance. Installation will begin in September 2021.
The retrofit reflects a general desire by PHOENIX to enhance its environmental friendliness and, more immediately, will enable the vessel to meet emission standards in the key Norwegian Heritage Fjord market. For the project, MAN PrimeServ prioritised keeping hazardous emissions to a minimum while maintaining engine performance and propulsion efficiency.
MAN PrimeServ Augsburg has previously retrofitted the Amadea’s turbochargers, in the process improving engine efficiency and significantly reducing CO2 emissions, and also introduced MGO instead of HFO injection nozzles in order to minimise black-carbon emissions. The combined work carried out on the vessel reflects MAN Energy Solutions’ desire to increasingly become a supplier of complete propulsion solutions.
The MAN SCR solution will bring the Amadea’s engines from Tier 0 status to Tier III emission level, and will reduce NOx emissions by 90%, equivalent to savings of 600 tons per annum. MAN’s SCR system is the greenest solution available on the market with the highest operational readiness and safety: the SCR will be available from just 15% engine load, enabling clean operation, also during slow-sailing in the fjords as well as close to port and populated areas.
The fully modular SCR solution will be integrated into the Amadea’s engine-control system. With its closed-loop system and a weather station that uses environmental data, the NOx-reduction rate is maximised and ammonia-slip minimised to just 10 ppm, comparable to that of a car. Low ammonia slip is not just good because ammonia is a greenhouse gas and affects the climate, but also because it reduces urea consumption, enabling the urea-tank size to be reduced.
