Combined Acoustic and Hydrodynamic Experimental Data Acquisition in Towing Tank: Moonpool Experiments Available to Purchase

Time and cost effective experimental verification and accuracy procedures are the first and utmost requirements in ship building research conducted in towing tank. This paper presents towing tank experimental setup and procedures to acquire acoustic and hydrodynamic data at the same time for a moonpool experiment. The same technique can be applied on a variety of configurations to acquire combined acoustic and hydrodynamic data. In present work the experimental technique possesses the ability to monitor pressure fluctuations, acoustics, free surface wave height inside a moonpool and structural vibration of a moonpool model at the same time with a better estimation and accuracy. The results are compared with numerical modeling, empirical relations and a detailed collected data comparison analysis is given in light of ‘Empirical Mode Decomposition’ (EMD) method. Collected data from sensors are proved to be in engineering practice limits proving the importance and authenticity of the data acquisition procedure discussed here. We believe that the results and methods given in this paper have surely a permanent space in the technical literature.
