Abstract:
Some results of the concept working out are proposed to improve ecological
parameters in the inland Danube navigation by increasing energy efficiency of the already owned
fleet at the basis of possible methods, which also were proposed during GRENDEL (Green and
Efficient Danube Fleet) Project, finished in November, 2020. It has been a pilot project directed
to coordinate the Danube fleet modernization according to the European Green Deal conception.
The results, introduced during GRENDEL Final Event show an active interest of all participants
to the main objectives of the project, and both to the prolongation of investigations in this sphere.
Obviously, the main interest is concentrated around issues of harmful emissions of ship main
engines decreasing as soon as preparing Danube inland vessels for using technologies of zero
emission. However, very expensive practical realization, Danube market falling, pandemic
limitations, points of wasteland in Danube countries economics – these all factors make
impossible to use modern findings and solutions in sphere of the Danube fleet modernization for
today’s shipowners. Nowadays shipowners are using to feel financial deficits even for current
operational maintenance
