Cruise ship Amadea to be retrofitted with new green system

MAN Energy Solutions’ after-sales division in Augsburg, Germany has developed an ultra-compact SCR (Selective Catalytic Reduction) system that will be retrofitted aboard Amadea, a cruise ship chartered by Phoenix Reisen (Germany) and managed by BSM Cruise Services, and will meet exacting Norwegian emission standards.

The retrofit devised by MAN PrimeServ Augsburg sees 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.

Alexander Schäfer, Head of MAN PrimeServ Turbocharger & Exhaust Gas Treatment said: “The concept of clean cruising is a major, coming trend within the cruise industry and the Amadea therefore runs on high-quality marine diesel-oil alone.

“With our SCR solution, Phoenix and BSM are establishing themselves as trailblazers within the segment in terms of emission reduction. It is always a pleasure to be part of something extraordinary that benefits the environment.”

MAN PrimeServ Augsburg has previously retrofitted 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.
