Oil discharge
The International Convention for the Prevention of Pollution from Ships, or MARPOL, is a critical international marine environmental convention. It was developed by the International Maritime Organization (IMO) to minimize pollution of the oceans and seas, including dumping, oil, and air pollution.
MARPOL 73/78, which came into force in 1973 and was revised by the protocol in 1978, aims to ensure that shipping remains the least environmentally damaging mode of transport. It preserves the marine environment by eliminating pollution from harmful substances discharged from ships, including oil discharge.
MARPOL Annex I, which came into force on 2 October 1983, specifically addresses the discharge of oil into the ocean environment. It incorporates the oil discharge criteria prescribed in the 1969 amendments to the 1954 International Convention for the Prevention of Pollution of the Sea by Oil (OILPOL).
Annex I includes regulations for the treatment of engine room bilge water for all large commercial vessels and ballast and tank cleaning waste. It also introduces the concept of ""special sea areas," which are considered at high risk of oil pollution. Discharge of oil within these areas is strictly prohibited, with minimal exceptions.
To minimize oil discharge during ship operations and accidents, Annex I specifies tanker design features. For instance, new oil tankers must be fitted with segregated ballast tanks to eliminate the need to carry ballast water, reducing the risk of oil spills.
MARPOL has been successful in reducing operational pollution, such as from routine tank cleaning, and the continuous decline of accidental oil pollution over the last 30 years is attributed to its regulations.
In addition to Annex I, other annexes also contribute to preventing oil discharge. For example, MARPOL Annex VI, which came into force in May 2005, focuses on preventing air pollution from ships, including oil discharge or oily mixtures, whether intentional or accidental.

Hazardous waste
MARPOL 73/78 addresses the disposal of ship-generated hazardous waste, such as cleaning agents and cargo hold washing water. It sets standards for stowing, handling, and shipping, and lays down rules for waste disposal.
Annex I of MARPOL 73/78, which came into force on 2 October 1983, specifically addresses the prevention of pollution by oil. It includes regulations for tanker design features to minimise oil discharge during operations and accidents. It also covers the treatment of engine room bilge water and ballast and tank cleaning waste.
Annex II, which also came into force in 1983, focuses on the discharge criteria for eliminating pollution by noxious liquid substances carried in large quantities. It divides substances into categories and introduces detailed operational standards and measures. The discharge of pollutants is strictly controlled and only allowed at certain distances from the nearest land.
In addition to annexes targeting specific types of pollutants, MARPOL 73/78 also includes more general provisions for preventing pollution. For example, it addresses the different types of garbage that may be discharged and specifies the distances from land and the manner in which they may be disposed of. Importantly, it imposes a complete ban on the disposal of plastics into the sea.

Sewage
MARPOL 73/78, or the International Convention for the Prevention of Pollution from Ships, is a convention that aims to minimise pollution of the oceans and seas. It was developed by the International Maritime Organization and came into force on 2 October 1983.
One of the main pollutants that MARPOL 73/78 addresses is sewage. Sewage pollution from ships is regulated under MARPOL Annex IV, which came into force on 27 September 2003. The annex introduces requirements to control and prevent sewage pollution from ships, with a focus on restricting the discharge of sewage into the sea.
According to MARPOL, the discharge of sewage into the sea is prohibited unless the ship meets certain conditions. Ships are allowed to discharge sewage into the sea if they have an approved sewage treatment plant in operation or if they are using an approved system to discharge comminuted and disinfected sewage at a distance of more than three nautical miles from the nearest land. If the sewage is not comminuted or disinfected, it must be discharged at a distance of more than 12 nautical miles from the nearest land.
To ensure compliance with these regulations, MARPOL Annex IV includes requirements for surveys and certification. Regulations 4 and 5 provide details for the issue or endorsement of certificates, while Regulations 7 and 8 specify the form, duration, and validity of the sewage pollution prevention certificate. Chapter 3 of Annex IV addresses the equipment and control of sewage discharge from ships, with Regulation 9 providing details of sewage system requirements. Regulations 10 and 11 outline the need for a standard sewage discharge connection to transfer sewage to port facilities and discharge sewage at sea within and outside particular areas.
In addition to the requirements for ships, MARPOL 73/78 also places responsibilities on signatory nations. Each country is responsible for enacting domestic laws to implement the convention and ensuring that vessels registered under their flag comply with its pollution prevention standards. This includes conducting their own examinations and taking action in cases of non-compliance.

Garbage
MARPOL 73/78, or the International Convention for the Prevention of Pollution from Ships, is a marine protection treaty developed by the International Maritime Organization (IMO). It was adopted on 2 November 1973 and later revised by the 1978 Protocol to address a rise in maritime accidents involving tankers. The combined convention entered into force on 2 October 1983.
MARPOL 73/78 is designed to minimize pollution of the oceans and seas, including dumping, oil, and air pollution. It includes six technical annexes with various chapters and regulations. One of these annexes, Annex V, specifically addresses garbage and waste disposal.
MARPOL Annex V:
Annex V of MARPOL 73/78, which came into force on 31 December 1988, focuses on the prevention of pollution by garbage from ships. It defines garbage as all kinds of food wastes, domestic wastes, operational wastes, plastics, cargo residues, incinerator ashes, cooking oil, fishing gear, and animal carcasses generated during the normal operation of a ship.
Annex V prohibits the disposal of garbage into the sea from ships, except in certain limited circumstances. It specifies the distances from land at which different types of garbage may be disposed of. For example, food waste that has been processed can only be discharged three nautical miles or more from the nearest land, while unprocessed food waste must be discharged at least 12 nautical miles from land.
Annex V also requires ships to maintain a Garbage Record Book to log the discharge or loss of certain items, such as fishing gear. Additionally, ships of 12 meters or more in length must display placards notifying the crew and passengers of the garbage discharge requirements.
Amendments to MARPOL Annex V:
MEPC.219(63), which came into force on 2 March 2012, further tightened the regulations by generally prohibiting the discharge of any garbage into the ocean, with specific exceptions for food wastes, cargo residues, wash water, and animal carcasses. MEPC.220(63), which also came into force on 2 March 2012, encourages the creation of waste management plans onboard vessels.
Implementation and Enforcement:
The implementation of MARPOL 73/78, including Annex V, is the responsibility of the individual signatory nations. Each country must enact domestic laws to comply with the convention and its annexes. For example, Australia has implemented Annex V and provides Garbage Placards to ships, as well as ensuring that adequate reception facilities are available in ports and terminals to manage ship-generated waste.
The country where a ship is registered, known as the Flag State, is responsible for certifying the ship's compliance with MARPOL's pollution prevention standards. If a ship is found to be non-compliant, the country that detects this non-compliance can detain the ship.

Air pollution
The International Convention for the Prevention of Pollution from Ships, known as MARPOL 73/78, is a critical international marine environmental convention. It was developed by the International Maritime Organization (IMO) to minimize pollution of the oceans and seas, including dumping, oil, and air pollution. The original MARPOL was signed on February 17, 1973, but the current convention combines the 1973 Convention and the 1978 Protocol, which entered into force on October 2, 1983.
MARPOL 73/78 has six technical annexes, and Annex VI specifically addresses air pollution from ships. This annex was adopted to prevent the intentional or accidental discharge of oil or oily mixtures from ships, and it consists of 11 chapters containing 47 regulations. While the regulations may not apply to all ships, they provide important guidelines for controlling air pollution in the maritime industry.
Annex VI sets limits on sulphur oxide and nitrogen oxide emissions from ship exhausts, aiming to reduce the release of these pollutants into the atmosphere. It also prohibits deliberate emissions of ozone-depleting substances, with designated emission control areas enforcing stricter standards for SOx, NOx, and particulate matter. To ensure compliance, the IMO has implemented regulatory and practical measures, such as the Carriage Ban and Ship Implementation Plan, allowing for the detection of non-compliance during port state controls.
In addition to Annex VI, other annexes of MARPOL 73/78 contribute to air pollution prevention indirectly. For example, Annex I, which deals with the discharge of oil into the ocean, includes regulations for the treatment of engine room bilge water. By minimizing oil discharge during ship operations and accidents, Annex I helps reduce the release of volatile organic compounds and other pollutants that contribute to air pollution.
Furthermore, MARPOL 73/78 also addresses the discharge of harmful substances beyond oil. Annex II, for instance, focuses on the elimination of pollution by noxious liquid substances carried in large quantities. It sets strict discharge criteria and operational standards to prevent the release of these substances into the environment, which could otherwise contribute to air pollution through evaporation or combustion processes.
