REDUCING ACCOMMODATION NOISE DUE TO TRANSVERSE THRUSTERS IN LARGE SHIPS

The large, sea-going drilling ship Pelican is fitted with two stern and three bow thrusters which are a considerable source of noise during operations. The bow thrusters are situated in way of the accommodation presenting a serious noise nuisance to the off-duty members of the crew. In order to ascertain the efficiency of the acoustical countermeasures, measurements of structure-borne noise were made during the operation of the ship's thrusters. Equivalent source levels were obtained for a number of positions on tweendeck 3, the results being plotted in a series of graphs, showing, inter alia, the effects of isolating the thrusters and of insulating the cabins.
