5668 TEU集装箱船球艏改型与浮态节能的实船验证
|
摘要
针对目前集装箱船大多处于偏离原设计状态的低载货量及降速航行状态,快速性较差的问题,提出球艏改型和浮态节能技术2种节能方案,并以5 668 TEU型集装箱船为例对这2种节能方案进行实船验证。研究分析该型集装箱船的实际营运状态特点,阐释球艏改型与浮态节能的关系,拟定实船验证的技术路线。通过对2艘姊妹集装箱船(原球艏船和改型球艏船)进行试航,对球艏改型(船)和浮态节能技术进行实船验证。经验证,球艏改型和浮态节能技术的效果明显,且改型球艏船更加适应低载货量、降速航行的营运现状。
Due to the weak shipping market,most container vessels are in a state of low cargoes and slow steaming at present,which deviates from the original design point,leading to poor power-speed performance. To solve this problem,two energy saving measures are proposed,i. e. bulbous bow retrofit and trim optimization energy-saving technologies,for a certain type of container vessel. The container ships' navigational data are analyzed to master the characteristics of the navigation condition; The relationship between bulbous bow retrofit and trim optimization is studied to work out the technical route; Sea trials of two sister container vessels( an original bulbous bow ship and a retrofit bulbous bow ship) are carried out to validate the bulbous bow retrofit and trim optimization. It is proved that bulbous bow retrofit and trim optimization are effective for energy-saving,and the bulbous bow retrofit technology fits perfectly to the current status of low cargoes and slow steaming.
