“…In contrast with the flourishing literature and number of mitigation actions for the aforementioned noise sources, very little attention has been paid to addressing noise produced by ports in their surroundings. Most of the scientific studies about noise generated from vessels concern onboard noise [29][30][31] or interference with animal life [32][33][34] and oceanic ambient noise [35,36], since, currently, noise produced underwater is more studied than airborne noise [37][38][39][40]. Overall underwater ship-radiated noise is the sum of propulsion noise, propeller noise, auxiliary noise, and hydrodynamic noise [41], with eventual tonal components caused by the propeller and associated cavitation noise [42].…”

After the European Environmental Noise Directive prescribed noise maps and action plans, wide scientific literature and a consistent number of mitigation strategies emerged for road, railway, airport, and industrial noise. Unfortunately, very little attention has been paid to the noise produced by ports in their surroundings, even though there could be many areas affected by it. At present, more attention seems to be paid to noise produced underwater, mostly for military and security reasons and for its interference with wildlife, rather than airborne noise and its influence on human health. In the framework of a project aiming to shed more light on a topic so far under-investigated, this paper presents an acoustical characterization of different small vessels at various speeds that move around on a daily basis in every type of port, produced by means of short- and long-term measurements. The new information acquired was used to produce a map of noise generated by vessels moving in Livorno’s canals, which branch off in a densely inhabited area. The simulations were validated using long-term measurement. The number of citizens exposed was also estimated and used to calculate the number of highly annoyed people according to the recent curve for road traffic noise proposed by Guski et al. In order to prevent citizen exposure to noise and possible complaints about small boats, different scenarios and possible future situations such as various vessel speeds, limited flow, restricted areas for some categories, or new residential areas were studied.

“…In addition, the age and technical condition of used propulsion systems is being regulated [5] [6]. At the same time, the accompanying issue of noise pollution is an increasing source of concern [7] [8]. This directly results in a conclusion that in the near future, environmental concerns -mainly the awareness that certain environmental changes resulting from pollution cannot be reversed -might become of such high importance that the currently used propulsion systems will not be allowed to operate any longer.…”

In recent years, there has been a significant development in “green” and energy efficient propulsion systems, which fits into the general trend of environmentally friendly “green shipping”. The pursued goal is to construct a safe passenger ship that is low in energy demand and equipped with a highly energy efficient, emission-free propulsion system. The paper presents main problems encountered by designers of a small, hybrid-powered ferry powered lithium batteries. The conducted research allowed to create a design of an energy efficient hull shape, which decreases the demand for energy. Completed remote control model tests resulted in a proposal of an energy efficient and safe propulsion system with good manoeuvring capabilities. Measurements completed on an existing ferry permitted completing energy balance and forming an energy management policy. The paper contains the emission calculations computed for the existing ferry that are necessary for the environmental impact analysis. The soon to be constructed, newly designed vessel will provide a valuable contribution to hybrid-propulsion, energy management and unmanned technologies research.

“…Numerous publications by authors from all over the world can be found in recent literature which focus on economic issues of applications of propulsion systems on inland and sea-going vessels and their effect on the environment [12] [17]. More and more attention is also paid to noise emission by watercraft units [18] [19]. This issue is of special importance in inland navigation, in which the waterways frequently lead through densely urbanised areas.…”
