In which year did MARPOL enter into force?

The correct year that MARPOL entered into force is 1983. MARPOL, or the International Convention for the Prevention of Pollution from Ships, was adopted in 1973 and came into effect with the requirements implemented starting from 1983. This convention is significant as it established regulations aimed at minimizing pollution of the seas from ships, thereby promoting marine environmental protection. The year 1983 marks the formal inception of these regulations, laying the groundwork for the comprehensive legal framework that governs maritime pollution prevention to this day. Understanding this landmark event is crucial for anyone involved in marine operations, environmental management, or maritime law.
