The story of MARPOL, one annex at a time — legal applicability, discharge standards, special areas, latest MEPC updates and the road map for flag-State enforcement. Plus the daily questions every officer answers at sea: what may I discharge, where, and what do I log?
MARPOL 73/78 in one minute
The International Convention for the Prevention of Pollution from Ships (MARPOL) is the IMO's central environmental treaty. The 1973 Convention never entered into force on its own — it was absorbed by the 1978 Protocol, giving us today's "MARPOL 73/78". Implementation is driven by the IMO's Marine Environment Protection Committee (MEPC) and enforced by flag States (certificates, surveys) and port States (PSC inspections).
