MARPOL

8 lessons

Pollution-prevention rules seafarers must know cold: MARPOL Annexes I–VI — oil, chemicals, packaged goods, sewage, garbage and air emissions — with discharge criteria, record books and PSC checks.

This chapter collects 8 illustrated lessons on MARPOL as part of Safety, ordered as they are best studied. It opens with MARPOL 73/78: The Convention & Its Six Annexes, MARPOL Annex I — Prevention of Pollution by Oil, MARPOL Annex II — Noxious Liquid Substances in Bulk, MARPOL Annex III — Harmful Substances in Packaged Form, MARPOL Annex IV — Prevention of Pollution by Sewage from Ships, MARPOL Annex V — Prevention of Pollution by Garbage from Ships and 2 more. Each lesson is written for MEO oral and written preparation: definitions first, then how the system behaves, then the checks and figures used in practice.
