The International Maritime Organization is a specialised agency of the United Nations responsible for regulating maritime transport. 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 on 17 March 1958. Headquartered in London, United Kingdom, the IMO, in 2024, has 176 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.
Fuel oil is any of various fractions obtained from the distillation of petroleum. Such oils include distillates and residues. Fuel oils include heavy fuel oil, marine fuel oil (MFO), furnace oil (FO), gas oil (gasoil), heating oils, diesel fuel, and others.
A cargo ship or freighter is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped.
A boat or ship engaged in the tramp trade is one which does not have a fixed schedule, itinerary nor published ports of call, and trades on the spot market as opposed to freight liners. A steamship engaged in the tramp trade is sometimes called a tramp steamer; similar terms, such as tramp freighter and tramper, are also used. Chartering is done chiefly on London, New York, and Singapore shipbroking exchanges. The Baltic Exchange serves as a type of stock market index for the trade.
A second mate or second officer (2/O) is a licensed member of the deck department of a merchant ship holding a Second Mates Certificate of Competence, by an authorised governing state of the International Maritime Organization (IMO). The second mate is the third in command and a watchkeeping officer, customarily the ship's navigator. Other duties vary, but the second mate is often the medical officer and in charge of maintaining distress signaling equipment. On oil tankers, the second mate usually assists the chief mate with the cargo operations.
Protection and indemnity insurance, more commonly known as P&I insurance, is a form of mutual maritime insurance provided by a P&I club. Whereas a marine insurance company provides "hull and machinery" cover for shipowners, and cargo cover for cargo owners, a P&I club provides cover for open-ended risks that traditional insurers are reluctant to insure. Typical P&I cover includes: a carrier's third-party risks for damage caused to cargo during carriage; war risks; and risks of environmental damage such as oil spills and pollution. In the UK, both traditional underwriters and P&I clubs are subject to the Marine Insurance Act 1906.
Chartering is an activity within the shipping industry whereby a shipowner hires out the use of their vessel to a charterer. The contract between the parties is called a charterparty. The three main types of charter are: demise charter, voyage charter, and time charter.
Marine insurance covers the physical loss or damage of ships, cargo, terminals, and any transport by which the property is transferred, acquired, or held between the points of origin and the final destination. Cargo insurance is the sub-branch of marine insurance, though marine insurance also includes onshore and offshore exposed property,, hull, marine casualty, and marine losses. When goods are transported by mail or courier or related post, shipping insurance is used instead.
A charterparty is a maritime contract between a shipowner and a "charterer" for the hire of either a ship for the carriage of passengers or cargo, or a yacht for leisure.
Marine safety is one of the eleven missions of the United States Coast Guard.
An oil tanker, also known as a petroleum tanker, is a ship designed for the bulk transport of oil or its products. There are two basic types of oil tankers: crude tankers and product tankers. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets.
The NorthStandard P&I Association or Club is a marine mutual liability insurer in the United Kingdom.
The Erika legislative packages of the European Union are maritime laws intended to improve safety in the shipping industry and thereby reduce environmental damage to the oceans.
Marine fuel management (MFM) is a multi-level approach to measuring, monitoring, and reporting fuel usage on a boat or ship, with the goals of reducing fuel usage, increasing operational efficiency, and improving fleet management. MFM has grown in importance due to the rising costs of marine fuel and increasing government oversight of the pollution generated by the world's shipping fleet.
The environmental impact 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.
International Convention on Oil Pollution Preparedness, Response and Co-operation (OPRC) is an international maritime convention establishing measures for dealing with marine oil pollution incidents nationally and in co-operation with other countries. As of November 2018, there are 112 state parties to the convention.
Slow steaming is the practice of operating transoceanic cargo ships, especially container ships, at significantly less than their maximum speed. In 2010, an analyst at the National Ports and Waterways Institute stated that nearly all global shipping lines were using slow steaming to save money on fuel.
Seaworthiness is a concept that runs through maritime law in at least four contractual relationships. In a marine insurance voyage policy, the assured warrants that the vessel is seaworthy. A carrier of goods by sea owes a duty to a shipper of cargo that the vessel is seaworthy at the start of the voyage. A shipowner warrants to a charterer that the vessel under charter is seaworthy; and similarly, a shipbuilder warrants that the vessel under construction will be seaworthy.
Bridge OperationsQuality Assurance is a methodology utilised in shipping and which originates from the similar FOQA/FDM concept in aviation. BOQA is a methodology with which ship owners/operators, ship Captains, and other associated shipping stakeholders can automatically and systematically monitor, track, trend and analyse operational quality of (seagoing) vessels. The main target with BOQA is to provide a non-punitive platform for proactive analysis of vessel data to enable the enhancement of maritime safety. The BOQA methodology can be used in both conventional crewed ships and in autonomous or uncrewed vessels provided that adequate data sources are available.
