摘　　要：为给现有船舶寻找一种方便、有效的节能措施,以5 668 TEU集装箱船为例进行节能研究。通过统计其以往的运营资料,分析其航行状态,发现船舶航行状态较差主要体现在球鼻艏与当前的航行条件不匹配。对此,提出对球鼻艏进行改造的节能措施。以权衡设计理念为指导,以模型试验结合数值分析作为球鼻艏优化手段,通过模型试验验证节能效果并将其应用到实船。测试结果表明:改造后的船舶在常用状态下节能效果显著。Container ships often operate at lighter draughts and lower speeds recently, therefore, at bff design＇ conditions with poor performance. The navigational data of 5 668 TEU container ships is analyzed and shows that their bulbous bows do not match operating draughts and speeds, which leads wave resistance increase. Retrofit of bulbous bow is an effective way to improve the performance. The bulbous bow is optimized with numerical simulation and experiment analysis from the angle of resultant effect of speeds and draughts. Effect of the new bulbous bow is verified tbrough model tests. Operation tests of the ship with new bulbous bow show that it performs well under practical navigation conditions.
