Abstract
Recently, the reduction of ship noise and underwater radiated noise has become animportant issue. Engines and Z-pellers (azimuth thrusters) are considered as major sources of noise, and a quantitative evaluation of each sound source is required. In this paper, the contributions of engine and Z-peller were evaluated by noise and vibration measurement results in a hybrid tug ship. In order to predict the structure-borne noise level from the engine, an excitation force measurement was performed for both rigid and rubber-mounted engines. Underwater radiated noise emitted from the Z-peller was evaluated from cavitation noise tests using a water tank. In these tests, two types of Zpeller configurations were proposed, and the noise reduction effect was confirmed. Theresults are presented in this paper.
