大型集装箱船的结构特点及其操纵分析 [摘要] 大型集装箱船是远洋货物运输重要的运载工具,对其操纵性能的了解直接关系到运输效率及航行安全。本文根据一些前人资料结合笔者自己所学的知识简要的介绍了集装箱船的历史及通过对大型集装箱船的船型、侧推器、风压力、旋回性、加速、减速及停船性能的分析,并在船型、风压力和旋回性上与大型油船、散货船进行比较,总结出大型集装箱船具有旋回性较差、舵力和舵力转船力矩较大、风压差较大、船速较高、倒车停船性能较好等操纵特点。根据这些特点,在进出港的操纵过程中,为了减小下风漂移,可适当提高船速,在接近码头过程中适时进行倒车减速或用拖船协助减速。实践表明,这些策略对实际操纵具有指导意义。可以为在集装箱船上工作的海员们提供一些专业性的参考。 [关键字]集装箱船 结构特点 操纵性 航行安全 1 Large container ship’s structural characteristics and analysis of its manipulation [Abstract] Large ocean-going cargo container ship is an important means of delivery, understanding its maneuverability is directly related to transport efficiency and safety of navigation. Information according to some combination of the previous paper the author learned in his brief introduction to the history of container ships and large container ship by ship, tunnel thrusters, wind pressure, gyration, acceleration, deceleration and stopping performance analysis, and In the ship, the wind pressure and the gyration with large oil tankers, bulk carriers were compared, summed up the large container ships with a cycle of poor rudder force and moment of a larger rudder, turned the ship, the wind pressure greater, speed high, reversing stopping manipulation features such as better performance. According to these characteristics, manipulation of the process in and out of port, in order to reduce downwind drift, it is appropriate to improve the speed of the ship, near the Pier during the slowing down or reversing a timely manner to assist with the tug to slow down. Practice shows that these strategies provide guiding significance for the actual manipulation of ship. And it could provide some professional reference for the seafarers working on container ship.
