The measurement of radiated noise from ships to meet the
recently published international standards is a challenging
undertaking. In the absence of a fixed noise range a vessel
deployed mobile hydrophone array is the most viable alternative.
The design and deployment methodology of such an array will
inevitably have significant implications on the reliability and
uncertainty of the measured data due to possible self-noise of the
array. The data presented in this paper provide an indication of
some of the practical issues encountered with the deployment of a
typical array
