Lecture: OPS Master Plan for Spanish Ports Project. Study of potential acoustic benefits of on-shore power supply at berth
Author(s): Santander Alvaro, Aspuru Itziar, Fernandez Pilar
Summary:
The “OPS Master Plan for Spanish Ports” project aims at drafting a Master Plan for the supply of electric power to ships at berth in Spanish Ports. In addition to the development of pilot cases that will provide electrical equipment in some ports and the adaptation of the ships that dock there, the project includes series of technical studies to identify the environmental benefits linked to the implementation of this new technology. This framework has supported the development of an analysis of the potential reduction of acoustic impact from ships at berth if power is supplied from the electric grid instead of using auxiliary engines generators. This issue has been already studied and it is known that there are other sources of noise from ships at berth (ventilation inlets/outlets from engines room and cargo decks, and reefers) that continue operating and could reduce the potential acoustic benefits.\nThe communication presents results achieved in this study, considering only the noise coming from the ships and excluding the loading and unloading activities or other installation at port. Noise measurements were conducted in the Bilbao Port to estimate the sound power of relevant noise sources of three types of ships: container, Ro-Ro and cruiser. An estimation of the acoustic benefits of the OPS is developed and although the number of ships measured cannot be considered representative, it is discussed how these types of ships could be classified to predict the acoustic benefits of OPS implemented in a port
