Sažetak
In this paper, the noise predictions on board ro- ro passenger ship and self-propelled cutter suction dredger are performed, by means of the general noise assessment software Designer-NOISE which is based on the hybrid Statistical Energy Analysis. All typical noise sources in ships (main engine, auxiliary engines, propeller, HVAC, exhaust system, etc.) as well as the non-typical ones in the latter case (sand moving through the pipelines, winches, dredging pumps, etc.) are taken into account. The prediction is based on vessels drawings and noise source properties, both provided by the shipyard. The A-weighted noise levels are evaluated in the frequency range from 63 Hz to 4 kHz. From the regulation viewpoint, BV Guidance Note NI-174-DNC and IMO Resolution A.468 (12) were applied and conclusions on the ship noise performances are drawn.
