为了确保大型集装箱船(350-400M)靠泊航行过程中的安全,通过对该类型船舶航行时的纵向受力分析,总结该类船舶的纵向运动特点和靠泊操纵措施:在两倍安全领域以外清爽的范围内,以符合港规的安全速度(12kn)航行;在两倍领域之内,开始减速,或停车淌航,抵达安全领域边界的速度为3kn;在受限的水域,应配置两艘拖轮伴航,以防应急局面;受风影响较大(横移,旋转)且接近码头的水域,需以最慢的带车速度慢行,以适合的风压角保证安全船位,尽可能缩短停车淌航的距离。停车淌航阶段,采取措施最大限度地减小风压角,合理配置拖轮克服风力的不利影响。通过实船操作验证上述措施的有效性和合理性。

In order to ensure the safety of large container ships (350-400m) during berthing and sailing, the longitudinal motion characteristics and berthing control measures of this type of ships are summarized by analyzing the longitudinal force of this type of ships during sailing. Within 2 times of the field, the speed to reach the boundary of the field is 3kN; In restricted waters, two tugboats should be deployed to accompany in case of emergency; In the water area which is affected by wind (lateral movement, rotation) and close to the wharf, it is necessary to move slowly with the slowest speed, ensure the safe position of the ship with the appropriate wind pressure Angle, and shorten the distance of stopping and sailing as much as possible. Stop the passage section, take measures to minimize the wind pressure Angle, rational allocation of tug to overcome the adverse effects of wind. The effectiveness and rationality of the above measures are verified by actual ship operation.
