英语翻译如大家所知的一贯惯例,在A港口外轮是禁止夜航的,从18:00-06;00期间是禁止靠泊的.该外轮19日晚上17.

仅供参考：As is the rule which we all know,Foreign ships are not allowed to cruise out side Port A during night time,and prohibited from mooring either from 18:00 to 6:00。However,the said foreign ship didn't arrive at the anchorage until 17:30 of the 19th。There are still 5-6 hours for her to get to the wharf from the anchorage。So it is no way she can be berthed by 18:00。Therefore,it is our argument that it is unreasonable and unacceptable to count the night of the 19th into the total time for demurrage charge。
