Attention is drawn to national laws in the appropriate volumes of Admiralty Sailing Directions. Actual or probable, discharges of oil or noxious substances, or sightings of pollution should be reported to the coastal authorities. Specific instructions on reporting, where known, are given in Admiralty List of Radio Signals Volume 1. MARPOL Annex I (Oil) entered into force on 2nd October 1983. It contains regulations for the prevention of pollution by oil. The United Kingdom domestic legislation to implement this Annex was the Merchant Shipping (Prevention of Oil Pollution) Regulations 1983. Discharging of Oil : The regulations govern the discharges, except for clean or segregated ballast, from all ships. They require inter alia all ships to be fitted with pollution prevention equipment to comply with the stringent discharge regulations. Discharge into the sea of oil or oily mixtures, as defined in an Appendix to the Convention, is prohibited by the regulations of AnnexI except when all the following conditions are satisfied. From the machinery space bilges of all ships, except from those of tankers where the discharge is mixed with oil cargo residue: The ship is not within a Special Area; The ship is more than 12nautical miles from the nearest land; The ship is en route; The oil content of the effluent is less than 15 parts per million. And; The ship has in operation an oil discharge monitoring and control system, oily-water separating equipment, oil filtering system or other installation required by this Annex. These restrictions do not apply to discharges of oily mixture which without dilution have an oil content not exceeding 15ppm. From the cargo area of an oil tanker (discharges from cargo tanks, including cargo pump rooms; and from machinery space bilges mixed with cargo oil residue): The tanker is not within a Special Area; The tanker is more than 50nautical miles from the nearest land; The tanker is proceeding en route; The instantaneous rate of discharge of oil content does not exceed 30litres per nautical mile; The total quantity of oil discharged into the sea does not exceed for existing tankers 1/15000 of the total quantity of the particular cargo of which the residue formed a part, and for new tankers (as defined in the Annex) 1/30000 of the total quantity of the particular cargo of which the residue formed a part; and The tanker has in operation, except where provided for in the Annex, an oil discharge monitoring and control system and a slop tank arrangement. Special and Particularly Sensitive Sea Areas. AnnexI applies to all such areas. Shipboard Oil Pollution Emergency Plans (SOPEP): Regulation26 of Annex1 to MARPOL 73/78 requires every oil tanker of 150grt and above and every other vessel of 400grt and above, to carry on board a SOPEP approved by the vessel’s flag administration. Regulation26 came into force on 4 April 1995 for all existing vessels. IMO has produced guidelines, as IMO Resolution MEPC 54(32), for the development of SOPEPs. This regulation also applies to offshore installations engaged in gas and oil production, seaports and oil terminals. Environment Aspects / Causes of Pollution from Ships The interface of ships with the marine and air environments can lead to their potential pollution in the following ways: 1. Pollution by Oil (including Oily Bilge Water) 2. Pollution by other Noxious substances & Packaged Harmful substances 3. Pollution by Garbage 4. Pollution by Sewage 5. Air pollution from Engine 6. Emission of Ozone-depleting substances 7. Leaching from Anti-fouling of Hull paint 8. Pollution by Ballast water (migration of invasive species) Items (1) to (6) above are governed by the MARPOL Convention Item (7) is in Convention on the Control of Harmful Anti-fouling Systems on Ships Item (8) comes under Convention for the Control and Management of Ships' Ballast Water and Sediments Any sighting of pollutant around or near the vessel should immediately brought to the notice of ships master and action to be taken to mitigate pollution as per SOPEP.
Prevention of Air Pollution from Ships Although air pollution from ships does not have the direct cause and effect associated with, for example, an oil spill incident, it causes a cumulative effect that contributes to the overall air quality problems encountered by populations in many areas, and also affects the natural environment, such as tough acid rain. MARPOL Annex VI, first adopted in 1997, limits the main air pollutants contained in ships exhaust gas, including sulphur oxides (SOx) and nitrous oxides (NOx), and prohibits deliberate emissions of ozone depleting substances (ODS). MARPOL Annex VI also regulates shipboard incineration, and the emissions of volatile organic compounds (VOC) from tankers. Following entry into force of MARPOL Annex VI on 19 May 2005,the Marine Environment Protection Committee (MEPC), at its 53rd session (July 2005), agreed to revise MARPOL Annex VI with the aim of significantly strengthening the emission limits in light of technological improvements and implementation experience. As a result of three years examination, MEPC 58 (October 2008) adopted the revised MARPOL Annex VI and the associated NOx Technical Code 2008, which entered into force on 1 July 2010. Revised MARPOL Annex VI The main changes to MARPOL Annex VI are a progressive reduction globally in emissions of SOx, NOx and particulate matter and the introduction of emission control areas (ECAs) to reduce emissions of those air pollutants further in designated sea areas. Under the revised MARPOL Annex VI, the global sulphur cap will be reduced from current 3.50% to 0.50%, effective from 1 January 2020, subject to a feasibility review to be completed no later than 2018. MEPC 70 (October 2016) considered an assessment of fuel oil availability to inform the decision to be taken by the Parties to MARPOL Annex VI, and decided that the fuel oil standard (0.50% sulphur limit) shall become effective on 1 January 2020. The limits applicable in ECAs for SOx and particulate matter were reduced to 0.10%, from 1 January 2015. Progressive reductions in NOx emissions from marine diesel engines installed on ships are also included, with a "Tier II" emission limit for engines installed on a ship constructed on or after 1 January 2011; and a more stringent "Tier III" emission limit for engines installed on a ship constructed on or after 1 January 2016 operating in ECAs (North American Emission Control Area and the U.S. Caribbean Sea Emission Control Area). Marine diesel engines installed on a ship constructed on or after 1 January 1990 but prior to 1 January 2000 are required to comply with "Tier I" emission limits, if an approved method for that engine has been certified by an Administration. The revised NOx Technical Code 2008 includes a new chapter based on the agreed approach for regulation of existing (pre-2000) engines established in MARPOL Annex VI, provisions for a direct measurement and monitoring method, a certification procedure for existing engines and test cycles to be applied to Tier II and Tier III engines.MEPC 66 (April 2014) adopted amendments to regulation 13 of MARPOL Annex VI regarding the effective date of NOx Tier III standards. The amendments provide for the Tier III NOx standards to be applied to a marine diesel engine that is installed on a ship constructed on or after 1 January 2016 and which operates in the North American Emission Control Area or the U.S. Caribbean Sea Emission Control Area that are designated for the control of NOx emissions. In addition, the Tier III requirements would apply to installed marine diesel engines when operated in other emission control areas which might be designated in the future for Tier III NOx control. Tier III would apply to ships constructed on or after the date of adoption by the Marine Environment Protection Committee of such an emission control area, or a later date as may be specified in the amendment designating the NOx Tier III emission control area. Further, the Tier III requirements do not apply to a marine diesel engine installed on a ship constructed prior to 1 January 2021 of less than 500 gross tonnage, of 24 m or over in length, which has been specifically designed and is used solely, for recreational purposes. Revisions to the regulations for ozone-depleting substances, volatile organic compounds, shipboard incineration, reception facilities and fuel oil quality were also made with regulations on fuel oil availability added.The revised measures are expected to have a significant beneficial impact on the atmospheric environment and on human health, particularly for those people living in port cities and coastal communities.

In Part One, 'Cargoes, Ships and Legislation', the special technical features of the different types of chemical tankers are described and the exacting, safe, operational practices. The programme uses four typical cargoes -- corrosive, toxic, flammable, and self-reacting -- to identify hazards and requirements in terms of cargo integrity, confinement and segregation on board. The programme also provides information on personal safety and personal protection equipment required. Current regulations in force are described, and in addition detailed reference is made to Material Safety Data Sheets, the Procedures and Arrangements Manual and the Certificate of Fitness. Emergency procedures relating to cargo handling during loading, at sea and when discharging are explained. Part Two, 'Prevention of Pollution', examines the four cargoes selected in Part One with a view to safe confinement on board and of pollution prevention during operations. Typical sources of pollution are described and the emergency procedures that crews need to be familiar with are explained in detail. The programme covers MARPOL Annex II requirements to prevent the discharge to sea of contaminated water, including during stripping and tank washing. Finally, the programme describes the restricted discharges from tank washing and outlines those that are totally prohibited.
