本研究是以流體動力之數學模式來模擬船舶在波浪中具岸壁效應的
運動，程式中將船舶視為細長體並運用了二維截片理論來計算。一般船舶運動之模擬是在頻率域中且無岸壁效應，然而當船舶繫於碼頭邊時岸壁效應的影響是相當重要的，而風力、洋流、波浪和繫纜力…等都將影響船舶運動。為了瞭解在這些情況下船舶的反應，時間域的船舶模擬分析是有必要的。此處岸壁效應是利用類似於雙體船的影像法來模擬，並以四階Runge-Kutta法來計算時間域中的船舶運動。船舶與岸壁間不同的間隙大小與幾種不同海況下之情形將被考慮。此研究可提供船舶停靠碼頭時其繫纜系統之配置設計。

In this study, a hydrodynamic mathematical model for simulating the ship motion in waves with the bank effect is presented. The two-dimensional method and the strip theory are applied on the calculations. Usually the ship motion simulations are done without bank effect in frequency domain. However the bank effect is important and significant while the ship is mooring near the quay or wharf. The ship motions will be affected by wind, current, waves, and the mooring force, etc. In order to understand the ship behaviors under such circumstance, the time domain simulation for ship motions is necessary. The bank effects are treated by using the image method which is similar to the treatments of the twin hull ship. The time domain simulation is made using the 4th order Rung-Kutta method. Several sea states will be considered with respect to different clearances between the ship and bank. The present studies will be helpful for the design on the mooring system arrangement of the ship near the quay or
wharf.
