The reduction of acceptable NOx emission requires additional after-treatment. An approved technical solution is the use of an SRC catalyser. However, this takes up a significant amount of space. With KeSS, we developed an idea of a combined emissions system with silencers and an SCR catalyser in just one shell. This system would be 30% smaller, lighter and more affordable than conventional systems comprising single components.

Prototype of the 4 MW test system
Comparison between a conventional emissions after-treatment system and the new, innovative KeSS system
The idea was realised and successfully tested for a 4 MW system. Afterwards, different variants were tested on a 500 kW engine. This resulted in the definition of two generally suitable concepts which could be used respectively depending on the construction conditions. The space, weight and cost savings aimed for were achieved. Today, two ships which feature the certified KeSS system have been successfully delivered. The partners have applied for a patent for the KeSS system.
