Behavier of the Large Tanker in Longitudinal Regular Waves

초대형선(超大型船)의 선형(船型) -종규칙파(縱規則波) 중에서의 운동응답(運動應答)에 대(對)하여

Heave and pitch amplitude and phase lag, relative vertical displacement, velocity and acceralation at bow as bow motion and wave exciting force and moment of a DWT 260,000 ton class tanker in the regular head wave have been calculated. All the calculations have been made by the computer program SD08 of Seoul National University. As the results it is cleared heave amplitude and acceralation have large value in the ballast condition and low Froude-number than full load condition and higher Froude numer as for as the $\frac{\lambda}{L}$ is lower than near around 1.0, however they have quite large values as $\frac{\lambda}{L}$ goes up.
