At what speed can non-hazardous NLS be discharged?

The correct speed for discharging non-hazardous Noxious Liquid Substances (NLS) is 7 knots. This regulation is established to mitigate the environmental impact of discharging these substances into the marine environment. The stipulated speed ensures that the discharge occurs at a rate that minimizes potential harm while allowing for efficient delivery of cargo during operations.

Regulatory frameworks set these limits to balance operational efficiency with environmental protection. By adhering to the 7-knot speed limit, vessels can comply with international and national regulations that aim to reduce pollution and protect marine ecosystems, thereby promoting safer and more sustainable shipping practices.
