| Summary: | The sustainability of anthropogenic activities at
sea is recently gaining more and more attention. As regards
shipping, emissions from ships into the environment
of various nature (engine exhaust gases, anti-fouling
paints leaching, ballast exchange, releases at sea of oil
and other noxious liquid or solid cargoes, of sewage and
of garbage) have been recognized as sources of pollution
and therefore controlled and limited since a long time.
The subject of noise emission has been identified only recently.
To study the problem, the EU has funded, among
others, the FP7 SILENV (Ship Innovative soLutions to rEduce
Noise and Vibrations) project that run from 2010 to
2012. In the present work, the holistic approach followed
within the project to characterize and control the ship as
a source of noise is presented. Three types of noise emissions
(in air, in water and inside the ship) are analyzed
highlighting peculiarities and different strategies adopted
to characterize the source, the impact on the receiver and
the possible solutions to set limits to the ship emissions.
The project outcome included a socalled “Green Label”: a
set of new prenormative requirements defined for the three
main areas mentioned above.
