Annexes I to III
Annex I covers pollution by oil and includes requirements such as the International Oil Pollution Prevention (IOPP) certificate and the Oil Record Book. Annex II covers noxious liquid substances carried in bulk. Annex III covers harmful substances carried by sea in packaged form.
Annexes IV to VI
Annex IV covers sewage from ships. Annex V covers garbage and prohibits the discharge of most types of waste, supported by a garbage management plan and record book. Annex VI covers air pollution, including limits on sulphur and nitrogen oxides and energy-efficiency measures, evidenced by the International Air Pollution Prevention (IAPP) certificate.
Records are the proof
Much of MARPOL compliance is demonstrated through accurate record-keeping. Inaccurate or incomplete oil and garbage record books are a well-known source of deficiencies, which is why complete review of these records pays off before an inspection.
