Abstract
The motion of ship in wave can be discussed in seakeeping and maneuvering. In model tests, the former is found by the motion response of waves while the latter requires captive model test to acquire hydrodynamic derivatives. The hydrodynamic derivatives in waves are discovered to be different from those in calm water. To understand better the behavior of maneuverability in waves, maneuvering tests in a wide range of waves are performed in this study. This study presents an experimental investigation into the maneuvering behavior of a container ship in regular waves, covering a wide range of wavelengths from half to twice the ship’s length. Captive model tests including Oblique Towing Tests (OTT) and pure sway tests were conducted in a towing basin. Maneuvering derivatives were found and suggests that third-order polynomial model may lacks sufficient flexibility to describe maneuverability in waves. Regarding high-frequency forces, components at multiples of the encounter frequency were observed with significant magnitude. The distribution of nonlinearity is found to be strongly dependent on wavelength.
