... ABSTRACT The analysis of the propulsion performance considering the ship motion in waves is an important factor for the efficient operation of a ship. The interaction between the propeller and the free surface due to the ship motion in waves has a great influence on the propulsion performance...

... over constant and sloped bottom. Ship motion over sloping bottom has been considered by Buchner (2006), Ferreira and Newman (2008) and Hauteclocque et al. (2009). To solve the ship motion, they have used panel method and have treated sloped bottom as extra body. However, this second-body approach...

... ABSTRACT: The second order wave exciting force on a floating ship considering tank liquid dynamic effect is examined. The second order drift forces are quadratic products of the first order quantities. The ship motions in wave considering tank liquid dynamic effect are calculated by linear...

... structures motion and wave loads on the storm wave is one of the most difficult problems in design and life cycle support. Nowadays, using computer technologies and numerical methods we can solve very complex practical problems. Last two decades the numerical simulators of the marine waves and ship motion...

... ABSTRACT: Wings, which are attached to near ship-bow bottom, is generally called bow wings. By using a bow wing, we can reduce added resistance of ships due to waves and ship motions. As even a fixed bow wing shows those performances, a movable wing is expected. To design the wings movable, we...

... ABSTRACT: It is known that ship motions in waves can be decreased by using a bow-wing. But it is not known that the bow-wing simultaneously decreases an added resistance and generates a thrust. A thrust is generated more efficiently by using the controlled bow-wings. We design a device...

... ( 8) In case the wave force or the magnifica- tion factor is large, the ship motion may set the fender into a nonlinear state. rhe stiff- ness nature of the fender may be character- ized as a bilinear curve, then EI can be ex- pressed as E ( 9 ) where Kx1 is the stiffness of the fender in the first...
