MAN Energy Solutions director Kjeld Aabo discusses balancing emissions demands, simplifying the engineroom, after treatment, digitalisation and marine lubricants with Marine Propulsion.
Having to consider different emissions can create a paradox, according to Mr Aabo. For example, when reducing NOx emissions to Tier II, it must be accepted that efficiency will be lowered.
He also notes that enginerooms have become a lot more complicated in the last 10 years, with optimised engines and new fuels being used to meet emissions regulations. Mechanical engines were a lot simpler – you could see what was happening and feel if something was wrong.
