La Spezia Container Terminal has installed new devices of acoustic avvisamento on means of large square

The new alarms use the so-called technology to "white sound"

The terminalista society La Spezia Container Terminal (LSCT) of the group Contship Italy has installed new devices of acoustic avvisamento on own means of large square with the scope to increase the level of safety for the workers and to diminish the impact in terms of acoustic emissions. Draft of alarms activated automatically during the maneuvers of backward motion of the carts and during the translation of the cranes to portal. New called devices BBS-tek® are realized by the Brigade Electronic, filial Italian of the English group Brigade Electronics, leader of market in the security systems in maneuver for vehicles.

The new alarms use the so-called technology to "white sound" and replace the old alarms based on emissions to "tonal sound", commonly used beginning from years ‘70. These devices guarantee immediate localization of the source (carts and crane and other cars operators) and thanks to the sound to broadband they are perceived in better way from the operators in large square while they wear the personal devices of safety - DPI (as the bob). The alarm to white sound emits a less annoying sound that is dispersed fastly and therefore is circumscribed to the single zone of danger. To 50 meters the reduction of the sound level measured equivalent already diminishes of beyond 4,5 dB regarding the precedence installed announcers of tonal type, so as demonstrated from the tests in operating conditions. They are meaningful decreases considering that every doubling of sonorous power corresponds to an increment of 3 dB.

"Al moment - Alfredo Scalisi has explained, general manager of the terminalista society spezzina - we have installed 21 announcers BBS Teak on the 22 reach stacker operating and seven BBS teak on the 12 operating RTG, but it is only a small part of the investments that in the past couple of years the terminal has put in field in order to mitigate the acoustic emissions". Scalisi has remembered that they are invested beyond 20 million euros for the average renewal of the park and the maintenance of the large squares and that the company is moreover working with the customers through the command ship in order to reduce, when possible, uses it of the generators during the permanence of the ships in port to demonstration of the LSCT engagement in order to act also on the sources that do not depend directly from own activity.

In occasion of the today's presentation of the new devices installed on means of LSCT, the mayor of La Spezia, Pierluigi Peracchini, than evidenced that until from the beginning the new municipal administration one has been interested to the problem of the acoustic pollution in a new way regarding the past. "Not in terms negatives, of contrast - it has specified Peracchini - but in terms of constructive dialogue with all the parts in cause. The port and the city are not two entity uniforms but the port is part integrating of the city, because it gives development, job and allows a local, regional, national increase economic. At the same time, but, a better cohabitation between the citizenship that weevers to tightened contact with this truth - it has observed the mayor - is right and the installation of these new devices represent a first concrete step towards this direction".
