Question

求高人帮忙翻译一下，谢谢！！！！！

请有经验的哥哥姐姐帮忙翻译一下下面的文字：中国交通运输部发布新的规定：所有来中国的国际航线的船只，在离港之前，必须进行污油水排放，否则不给签发出港签证。

我的表达如果哪里不合适，还望帮忙指正。如果有懂海事方面的高人，请将有关的专业术语告知我，不胜感激。
感谢两位的回答，前两天我找了两个朋友翻译了一下，然后我根据他们的翻译加上我的修改，整理如下，希望你们提出不同意见，大家一起探讨。

All vessels of international routes to China must be discharged oil sludge before departure. Otherwise the MSA will refuse to sign the port exit visas and other formalities.
