    Marpol Marpol Document Transcript

    • MARPOL NOTES Marpol is the International Convention for the Prevention of Pollution From Ships, 1973 as modified by the Protocol of 1978/97. Marpol is one of the most important international marine environmental conventions. It was designed to minimize pollution of the seas, including dumping, oil and exhaust pollution. Objectives To eliminate the pollution of the sea’s by oil, chemicals and other harmful substances which might be discharged during the operation To minimize the amount of oil that which is released due to accidents, collisions , groundings etc. Special Area: Means a sea area where for recognised technical reasons in relation to its oceanographical and ecological condition and to the particular character of its traffic the adoption of special mandatory methods for the prevention of sea pollution is required. There are certain special areas on the IMO website which have asterix in the column for “with effect from”. This is to indicate that the local government has not included the changes into the legislation or does not have adequate shore reception facilities. Also to keep in mind that even if the effective date is not applicable but if the flag state recognises the area as a special area then the vessel has to abide, also if the coastal state has local regulations the vessel will have to comply with those as well. The 6 annexes of MARPOL Annex 1: Regulation for prevention of pollution by oil Annex 2: Regulation for prevention of pollution by noxious liquid substances carried in bulk Annex 3: Regulations for the prevention of pollution by harmful substances carried in packaged form Annex 4: Regulation for the prevention of pollution by sewage from ships Annex 5: Regulation for the prevention of pollution by garbage from ships Annex 6: Regulation of prevention of air pollution from ships Annex 1 Special area as per annex 1 Mediterranean Sea North West European Waters Baltic Sea Oman area of the Arabian Sea Black Sea Southern South African waters Red Sea Antarctic area Persian Gulf
