The motion of ships in waves
WebAn inherent research topic in this laboratory is the so-called seakeeping performance of ships, which includes ship's performance in propulsion and motion dynamics in waves. By synthesizing the analysis tools developed so far, we are developing an analysis system for predicting long-term propulsive performance of ships in actual seas and ... WebMay 1, 2024 · Two right-handed Cartesian coordinate systems are used to describe the motion of the ship in beam seas of regular waves, (Fig. 1).The first one is the o-xyz system, in which the origin o is fixed on the free surface to describe the fluid motion, the y-axis points to the wave direction and the z-axis is vertically oriented upward.The other coordinate …
