TEKNOLOGI PENGENDALIAN EMISI ( 2 SKS) Jurusan Teknik Sistem Perkapalan ITS Surabaya
IMO Regulation IMO Regulation (MARPOL 73/78 Annex VI) Regulation International Maritime Organization (IMO) is an agency of the United Nations which has been formed to promote maritime safety. It was formally established by an international conference in Geneva in 1948, and became active in 1958 when the IMO Convention entered into force (the original name was the Inter-Governmental Maritime Consultative Organization, or IMCO, but the name was changed in 1982 to IMO) IMO ship pollution rules are contained in the “International Convention on the Prevention of Pollution from Ships”, known as MARPOL 73/78. On 27 September 1997, the MARPOL Convention has been amended by the “1997 Protocol”, which includes Annex VI titled “Regulations for the Prevention of Air Pollution from Ships”. MARPOL Annex VI sets limits on NOx and sulfur oxide emissions from ship exhausts, and prohibits deliberate emissions of ozone depleting substances.
