... but it is hard to predict roll motion because the theory just takes account of the wave radiation damping but fails to account for the viscous damping, flow separation, and vortex generation. And roll motion of ships is strongly related to viscosity effects and is extremely sensitive to viscosity-induced flow...

... case, the roll motion of a rectangular floating structure in regular wave has been simulated. KEY WORDS: wave-structure interactions; potential flow; viscous flow; nonlinearity; vortex INTRODUCTION Safety is always a main concern in the design of some of the offshore structures. Minimum air gaps...

... ABSTRACT: An adaptive operation of a disturbance accommodating controller(DAC) depending on the seastate number for roll motion of a ship is suggested. DAC suggested in this paper assumes the shape of the disturbance, i. e. the wave slope excitation as a harmonic signal that consists of two...

... ABSTRACT: Demand of good seakeeping performance is increasing for sea going vessels such as cruisers, naval ships and container ships. Especially roll motion is one of major concerns in evaluation of seakeeping performance because of its large resonance motion. Since large roll resonance...
