“…Furthermore, each single ship category has a series of peculiar operations and can emit in different ways, making it impossible to generalize the results. Studies have been dedicated to moored ships, to noise from machinery propagating through hull vibrations, aerodynamic noise produced by funnels, heating and ventilation systems [28,29,41,42]. However, less attention has been paid to cranes or loading/unloading operations.…”

“…As a consequence, ports have been poorly studied in the past, and only in recent years, some studies or projects concerning noise impact have been conducted [24][25][26]. Aiming at the acoustic characterization of a ship's sources, several authors studied noise emitted at berths [27][28][29], while our previous work dealt with small and large vessels in movement [30,31]. In addition to ships, many different sources (cranes, forklifts, reach stackers, etc.)…”

Maritime transportation is recognized to have advantages in terms of environmental impact compared to other forms of transportation. However, an increment in traffic volumes will also produce an increase in noise emissions in the surroundings for a greener source, as ports are frequently surrounded by urban areas. When more sources or higher noise emissions are introduced, the noise exposure of citizens increases, and the likelihood of official complaints rises. As a consequence, among the most demanding aspects of port management is effective noise management aimed at a reduction in the exposure of citizens while ensuring the growth of maritime traffic. At the same time, the topic has not been thoroughly studied by the scientific community, mostly because port areas are challenging from a noise management point of view; they are often characterized by a high degree of complexity, both in terms of the number of different noise sources and their interaction with the other main transportation infrastructure. Therefore, an effective methodology of noise modeling of the port area is currently missing. With regard to the INTERREG Maritime Program, the present paper reports a first attempt to define noise mapping guidelines. On the basis of the current state-of-the-art and the authors’ experiences, noise sources inside port areas can be divided into several different categories: road sources, railway sources, ship sources, port sources, and industrial sources. A further subdivision can be achieved according to the working operation mode and position of the sources. This classification simplifies actions of identification of the responsible source from control bodies, in the case that noise limits are exceeded or citizen complaints arise. It also represents a necessary tool to identify the best placing of medium/long-term noise monitoring stations. The results also act as a base for a future definition of specific and targeted procedures for the acoustic characterization of port noise sources.

“…The assessment of noise around ports is complicated, because the overall acoustic emission is the sum of roads, railways, or industrial installations in the area, as well as noise produced by ships themselves. Some authors investigated noise emitted from ships at berth [47][48][49][50][51] and all studies confirmed the complexity of the source. Internal machinery sources propagating trough hull vibrations, aerodynamic noise produced by funnels, heating and ventilation systems, and eventual outside cranes all contribute to the overall produced noise.…”

In the light of sustainability, satisfactory living conditions is an important factor for people’s positive feedback in their own living environment. Acoustic comfort and noise exposure should then be carefully monitored in all human settlements. Furthermore, it is already well-known that high or prolonged noise levels may lead to unwanted health effects. Unfortunately, while in the last decades scientists and public authorities have investigated the noise produced by roads, trains, and airports, not enough efforts have been spent in studying what happens around the coastal and port areas. Following the attention brought to the subject by recent European projects on noise in port areas, the present paper characterizes the sound power level and 1/3 octave band sound power spectrum of seagoing ships while moving at low speeds. Five different categories have been distinguished: Roll-on/roll-off (RORO), container ship, oil tanker, chemical tanker, and ferry. The analysis is based on a continuous noise measurement lasting more than three months, performed in the industrial canal of the port of Livorno (Italy). The resulting noise emissions are new and useful data that could be inserted in acoustic propagation models to properly assess the noise in the areas affected by port activities. Thus, the present work can act as a supporting tool in planning ship traffic in ports towards better sustainability.

“…The assessment of the impact is currently difficult due to the lack of specific standard instruments and indicators able to characterize and control the ship noise type [31][32][33][34][35]. Different approaches have been investigated in literature to evaluate ships sound power levels, considering ships both as mobile (ship under way) or stationary sources (ship berthed at wharf) [36][37][38][39][40][41][42][43][44], but a common method is still lacking.…”

The impact of environmental noise generated from ports: outcome of MESP project

et al. 2016

Ports are characterized by several complex operations. Accordingly, the analysis of noise results is complicated due to the presence in the same area of diverse sound from ships, trade and also from industrial and shipyards activities as well as auxiliary services producing negative effects on natural ecosystem and the urban population. The ENPI CBC MED project Managing the Environmental Sustainability of Ports for a durable development (MESP) addressed the pollution reduction from port activities through the implementation of a multidisciplinary approach in air, noise and water sectors, encompassing technological, regulatory and administrative solutions to ensure natural and urban sustainability and high level of life quality in surrounding territories. To prevent a heterogeneous development, the "status quo" of ports in Northern and Southern Shores of the Mediterranean Sea was analyzed and a guideline on methodologies, good practices and measurement assessment, adaptable and transferable in different port contexts was elaborated. To assess the procedures, validation tests have been carried out to different real cases. In noise sector pilot projects in the ports of Patras, Greece, and Tripoli, Lebanon, have been implemented. Due to the dissimilar scenarios, in terms of orography, facilities and activities, different noise mitigation actions and interventions were consequently accomplished.
