"Vessel arrival and departure" 是表示船舶进出港的常用英文表达。

"Vessel" 是指船只，"arrival" 是指到达，"departure" 是指离开。所以 "vessel arrival" 表示船只到达，"vessel departure" 表示船只离开。

下面是一些英文例句及其中文翻译：

The vessel is scheduled to arrive at the port at 8:00 am. 船预计在上午 8 点到达港口。
The vessel departure was delayed due to inclement weather. 由于恶劣天气，船的离港时间被延迟。
Please inform us of any changes to the vessel's arrival or departure time. 请通知我们有关船只到达或离开时间的任何变化。
