To provide experimental data on the hydrodynamic characteristics and features of DP (dynamic positioning) thrusters under variable operating conditions, wake measurements were performed on a DP thruster model using 2D LDV (laser Doppler velocimetry) and SPIV (stereoscopic particle image velocimetry). These tests were performed with and without a nozzle and over a range of advance coefficient values including the bollard pull condition. In this paper a detailed analysis of the hydrodynamic characteristics of the wake at a plane equal to a distance of 0.5 diameters downstream from the thruster, at advance coefficient values of 0, 0.4, and 0.45 are presented for both the LDV and SPIV measurements showing a comparison between the results of each technique. The effect of the duct and of changes in the advance coefficient values is presented in this paper.
