Abstract

A number of in situ measurements of source level radiated from various dredging ships were carried out with hydrophones attached to anchored buoys and suspended from a survey vessel to determine the noise level for each of these ships in UK coastal waters. In order to determine the distribution of the noise sources from the ships, a 7-element hydrophone vertical line array was deployed from the survey vessel to measure the radiated noise. A digital compass was attached to the array to determine the orientation of the array to aid the beam forming. The noise from various operational modes, such as dredging in opposite directions, pump off and transit was recorded and processed to demonstrate the differences in noise levels and positions of the sources in the water column. The results of beam forming on the noise are presented and it is shown that full dredging does generate a very wide spectrum of noise and the most likely source is from the inline pump.
