Built in the Fincantieri shipyards and launched in 1976, the Nazario Sauro submarine was retired in 2005 after covering a total distance of 111,875 miles with its 51-man crew. Renovated at the same shipyards, it is now enjoying a second lease of life at the heart of Costa Edutainment’s exhibition and on-shore pre-show at “Galata Museo del Mare” - a project with a total investment of €2.4 million. Before boarding the sub, visitors center the interactive pre-show in the harbour-side museum, designed by director Pierangelo Campodonico. This enables them to understand the hardships of a submariner’s life, try their skills at underwater and surface navigation and even earn a submariner certificate. Visitors board the sub in groups of 36 via a stairway installed by Fincantieri shipyards. This provides access to the first zone: the electrical control room. IBR’s Lucio Barbucci continues: “This area is fitted with a subwoofer, two enclosures and an interactive intercom. The room hosting the pumps used to control the ballast tanks is located below the motor room and, although not open to visitors, can be viewed through a grille in the floor, through which the noise of the pumps (reproduced by another Ecler enclosure) is heard”. The pump room hosts a rack containing an Ecler AMI2-70 amplified mixer with two mic/stereo line input channels, plus three Ecler MPA series multichannel amplifiers: an MPA6-80 six-channel unit, an MPA4-150 four-channel model and an MPA6-150 six-channel power amp. Another rack hosts the PCs that control the audio signals fed throughout the submarine, according to the status of the proximity sensors distributed along the visit route through the submarine and the electronic interfaces between the PCs, sensors and actuators. Barbucci continues: “The propeller shaft/electric motor room is not accessible to visitors, but it is visible through the access door, through which another enclosure hidden in the electric motor reproduces the changing noise level and tone of the engine according to crew control. The diesel engine room hosts the engines used to charge the submarine’s batteries: visitors pass along a narrow gangway between the two banks of engines along the left and right of the room and four enclosures hidden in the engine banks reproduce sounds of the start-up and running of the engine according to visitor traffic”. Located in the centre of the submarine are the non-commissioned officers’ quarters and the radio shack. The door of the latter is closed, but visitors can hear radio and telegraph communications with other craft (and interference), via another Audeo 106BK in the room.
