| Abstract: | The 21000 DWT multi-purpose ship is a liner of shanghai Ocean Shipping Company on south America route.According to the comprehensive analysis on voyage, ship numbers and schedule.the main engine delivered power of 7239. 75 kW is required to reach the ship speed of 16. 5 kn. when taking sea margin 15% into account. Aiming at this high ship speed index given by the ship owner. the bulhous bow design and the optimization tests on stern straightening ducts and rudder bulbs were carried out. The design idea and test results are introduced in the paper. |
