MARPOL
Home > Deck Cadet > Legislations & Conventions for Trainee > MARPOL
Marpol 73/78 is the International Convention for the Prevention of Pollution from Ships, 1973 as modified by the Protocol of 1978.
In 1997, a Protocol was adopted to amend the Convention and a new Annex VI was added which entered into force on 19 May 2005. MARPOL has been updated by amendments through the years.
Note : The Following 6 Annexes of MARPOL have been defined in simple Layman's Language, so as to just give an idea about the convention to the trainees and should not be used while applying it practically on board. To know more about MARPOL annexes refer to our main MARPOL page.

6. Harmful substances shall be properly stowed and secured so as to minimize the hazards to the marine environment without impairing the safety of the ship and persons on board.
7. Certain harmful substances may, for some scientific and technical reasons, need to be prohibited for carriage or be limited as to the quantity which may be carried aboard any one ship. In limiting the quantity, due consideration shall be given to size, construction and equipment of the ship, as well as the packaging and the inherent nature of the substances.
