...David Molyneux; Jie Xu; Neil Bose This paper presents the results of experiments to measure flow velocities around the hull of an escort tug model operating at a yaw angle of 45 deg using particle image velocimetry (PIV). The paper describes the setup, calibration, and operation of the PIV system...

... for displacement-type ships, Journal of Ship Research, 46, 3, 208–213]. These side bulbs are designed to create a wave pattern that interacts with the ship wave system of the hull at the desired speed range. This concept was first successfully tested on a coaster tanker and then extended to the UBC series hull...

...Hisayoshi Endo; Yasuhira Yamada The critical striking velocity (VBcr) and the critical collision angle (θcr) are introduced as the measures to represent the performance level of buffer bow. Those critical events are defined as the threshold whether the inner hull of struck tanker is ruptured...

...Roko Dejhalla; Zoran Mrša; Senka Vukovic´ A genetic algorithm-based optimization method is proposed for an optimization of a ship hull from a hydrodynamic point of view. In the optimization procedure, the wave resistance has been selected as an objective function. The genetic algorithm is coupled...
