船舶停靠在开敞式码头旁,受到风波和长周期波的作用,必然会产生各种运动,其中较为重要的是:纵荡、横荡、回转和起伏。不同的船型、货种、装卸操作等,其所允许的船舶位移量不同。右表系船长大于200米的大型船舶在长周期波作用下卸货时,船舶摆动周期60～120秒的情况下,其所允许的最大位移量。 Vessels docked at the open dock next to the turmoil and the role of long-period waves, will inevitably produce a variety of sports, of which the more important are: sag, sway, slewing and ups and downs. Different ship types, cargo types, loading and unloading operations, etc., which allow different ship displacement. The table on the right is the maximum allowable displacement of a large ship with a ship length greater than 200 meters when it is unloaded under the effect of long-period waves and the ship’s wobbling period is 60 to 120 seconds.
