The International Maritime Organization is a specialised agency of the United Nations responsible for regulating shipping. The IMO was established following agreement at a UN conference held in Geneva in 1948 and the IMO came into existence ten years later, meeting for the first time in 17 March 1958. Headquartered in London, United Kingdom, IMO currently has 175 Member States and three Associate Members.
The International Convention for the Prevention of Pollution from Ships, 1973 as modified by the Protocol of 1978, or "MARPOL 73/78" is one of the most important international marine environmental conventions. It was developed by the International Maritime Organization with an objective to minimize pollution of the oceans and seas, including dumping, oil and air pollution.
An oily water separator (OWS) (marine) is a piece of equipment specific to the shipping or marine industry. It is used to separate oil and water mixtures into their separate components. This page refers exclusively to oily water separators aboard marine vessels. They are found on board ships where they are used to separate oil from oily waste water such as bilge water before the waste water is discharged into the environment. These discharges of waste water must comply with the requirements laid out in Marpol 73/78.
An API oil–water separator is a device designed to separate gross amounts of oil and suspended solids from industrial wastewater produced at oil refineries, petrochemical plants, chemical plants, natural gas processing plants and other industrial oily water sources. The API separator is a gravity separation device designed by using Stokes Law to define the rise velocity of oil droplets based on their density and size. The design is based on the specific gravity difference between the oil and the wastewater because that difference is much smaller than the specific gravity difference between the suspended solids and water. The suspended solids settles to the bottom of the separator as a sediment layer, the oil rises to top of the separator and the cleansed wastewater is the middle layer between the oil layer and the solids.
Cruise ships carrying several thousand passengers and crew have been compared to “floating cities,” and the volume of wastes that they produce is comparably large, consisting of sewage; wastewater from sinks, showers, and galleys (graywater); hazardous wastes; solid waste; oily bilge water; ballast water; and air pollution. The waste streams generated by cruise ships are governed by a number of international protocols and U.S. domestic laws, regulations, and standards, but there is no single law or rule. Some cruise ship waste streams appear to be well regulated, such as solid wastes and bilge water. But there is overlap of some areas, and there are gaps in others.
In the United States, several federal agencies and laws have some jurisdiction over pollution from ships in U.S. waters. States and local government agencies also have responsibilities for ship-related pollution in some situations.
The environmental effects of shipping include air pollution, water pollution, acoustic, and oil pollution. Ships are responsible for more than 18% of nitrogen oxides pollution, and 3% of greenhouse gas emissions.
A magic pipe is a surreptitious change to a ship's oily water separator (OWS), or other waste-handing equipment, which allows waste liquids to be discharged in contravention of maritime pollution regulations. Such equipment alterations may allow hundreds of thousands of gallons of contaminated water to be discharged untreated, causing extensive pollution of marine waters.
A white box system is a mechanical system installed in the engine room of a ship for controlling and monitoring the engine room bilge water discharge from the vessel.
All cargo vessels where MARPOL Convention is applicable must have an oil record book in which the officer responsible will record all oil or sludge transfers and discharges within the vessel. This is necessary for authorities to be able to monitor if a vessel's crew has properly disposed of their oil discharges at sea.
Emission control areas (ECAs), or sulfur emission control areas (SECAs), are sea areas in which stricter controls were established to minimize airborne emissions from ships as defined by Annex VI of the 1997 MARPOL Protocol.
Oil Pollution Act of 1961, 33 U.S.C. Chapter 20 §§ 1001–1011, established judicial definitions and coastal prohibitions for the United States maritime industry. The Act invoked the accords of the International Convention for the Prevention of the Pollution of the Sea by Oil, 1954. The international agreement provided provisions to control the discharge of fossil fuel pollutants from nautical vessels on the high seas.
The Oil Pollution Act of 1973 or Oil Pollution Act Amendments of 1973, 33 U.S.C. Chapter 20 §§ 1001-1011, was a United States federal law which amended the United States Statute 75 Stat. 402. The Act of Congress sustained the United States commitment to control the discharge of fossil fuel pollutants from nautical vessels and to acknowledge the embargo of coastal zones in trans-boundary waters.
A marine sanitation device (MSD) is a piece of machinery or a mechanical system that is dedicated to treat, process, and/or store raw, untreated sewage that can accumulate onboard water vessels. It does not refer to portable devices such as portable toilets.
An oil content meter (OCM) is an integral part of all oily water separator (OWS) systems. Oil content meters are also sometimes referred to as oil content monitors, bilge alarms, or bilge monitors.
Oil discharge monitoring equipment (ODME) is based on a measurement of oil content in the ballast and slop water, to measure conformance with regulations. The apparatus is equipped with a GPS, data recording functionality, an oil content meter and a flow meter. By use of data interpretation, a computing unit will be able to allow the discharge to continue or it will stop it using a valve outside the deck.
Port reception facilities are a place that international shipping ports must provide to collect residues, oily mixtures, and garbage generated from an ocean-going vessel. contaminants generated by ships cannot be discharged directly to the ocean. According to MARPOL 73/78 they must be collected by the Port reception facilities all around the world. The Port reception facility must be able to receive dirty oil and other contaminants, and also provide quick and efficient services.
A variety of factors affect the water and marine life along the coastline of Lebanon. These factors include marine pollution, environmental impact of shipping, oil spills, noxious liquid substances spills, sewage spills, and the dumping of radioactive and medical waste. Despite being a hotspot for marine life within the Mediterranean, the Lebanese watershed and coastline is home to very high levels of pollution that threaten the human, animal, and plant life that rely upon it.
The International Convention for the Prevention of Pollution of the Sea by Oil (OILPOL) was an International Treaty signed in London on 12 May 1954. It was updated in 1962, 1969, and 1971. OILPOL was subsumed by the International Convention for the Prevention of Pollution from Ships (MARPOL) in 1973.
Heavy fuel oil (HFO) is a category of fuel oils of a tar-like consistency. Also known as bunker fuel, or residual fuel oil, HFO is the result or remnant from the distillation and cracking process of petroleum. For this reason, HFO is contaminated with several different compounds including aromatics, sulfur, and nitrogen, making emissions upon combustion more polluting compared to other fuel oils. HFO is predominantly used as a fuel source for marine vessel propulsion using marine diesel engines due to its relatively low cost compared to cleaner fuel sources such as distillates. The use and carriage of HFO on-board vessels presents several environmental concerns, namely the risk of oil spill and the emission of toxic compounds and particulates including black carbon. Presently, the use of HFOs is banned as a fuel source for ships travelling in the Antarctic as part of the International Maritime Organization's (IMO) International Code for Ships Operating in Polar Waters (Polar Code). For similar reasons, an HFO ban in Arctic waters is currently being considered.
