About MEPC.227(64)

The International Maritime Organization IMO. Marine Environment Protection Committee officially adopted the IMO.MEPC.227(64) resolution on October 5, 2012, which regulates Annex IV of the “MARPOL73/78 International Convention for the Prevention of Anti-pollution” regarding ship domestic sewage treatment equipment. The requirements have made new requirements. From January 1, 2016, all domestic sewage treatment devices hoisted on new and old ships must comply with the requirements of this convention.
