Maritime Terms, Abbreviations and Acronyms

Maritime abbreviations and acronyms go back to those days we used telegram and telex to communicate. The business model for telex and telegrams was “pay per letter”. Even though the telegrams and telexes have been retired, we still use the maritime abbreviations daily.

Below you will find a comprehensive list of terms, abbreviations, and acronyms used in the maritime industry, sorted in alphabetical order. You can search for an acronym or write a word and find the abbreviations where the word is included.

If you think some abbreviations are missing, send us an e-mail at post@maritimeoptima.com or open the chat icon on the bottom of this page.

Fuel

A material used to produce heat or power by burning.

Fuel blending

Mingling two or more materials, refinery streams ordinarily, to make a mixture that meets a grade of fuel's legal and commercial requirements. Refineries almost always sell finished products made from more than one component. Modern motor gasoline, for all practical purposes, must comprise several blendstocks. No single material can meet all its various specifications. Kerosene and gasoline do not require blending the way mogas does. But refinery economics and the number of processes which yield middle distillate fractions make combinations quite probable. Heavy fuel oil usually includes several streams in order to concoct a saleable material from the dregs of assorted units.

Fuel oxygenate

Oxygenates are compounds containing oxygen in a chain of carbon and hydrogen atoms. Today, oxygenates are blended into gasoline in two forms: alcohols or ethers. Ethanol is the most commonly used alcohol oxygenate; methyl-tertiary-butyl-ether, or MTBE, is the most commonly used ether oxygenate. Fuel oxygenates are used in gasoline to boost the octane rating and to decrease the toxic emissions in the exhaust.

Full and Down

An expression to describe a loaded vessel carrying cargoes of such a volume and weight that it fills all the vessel’s spaces and also brings her down to her tonnage loadline. A rare but optimum revenue condition for a vessel operator.

Full Containerships

Ships equipped with permanent container cells, with little or no space for other types of cargo.

Full Cycle Washing

Crude oil washing in which the complete cargo tank is washed.

Full Shipload Lot

The amount of cargo a vessel carries or is able to carry. Practically, it is the amount of cargo which induces the specific voyage. While the cargo lot may take up the majority of the vessel’s space or ton- nage capacity, it does not require a vessel’s volume and weight capacity to be fully utilized.

Fully Hydrogenated

The terms describing a fat or oil which has been hydrogenated to the extent that the resultant product is solid at room temperature. Products containing hydrogenated fats include heavy duty frying fats for restaurant use, solid shortenings and solid margarines.

Fully Refined Oil

The term used to describe an oil which has been subjected to extensive processing methods to remove - (1) free fatty acids and other gross impurities (refine); (2) naturally occurring colour bodies such as chlorophyll (bleach), and (3) volatile trace components which may affect colour, flavour and odour (deodorise).

Fungible

Marketable product. Typically refers to petroleum products moved by pipeline. As long as a particular grade of gasoline meets Colonial pipeline specifications, for instance, it may travel and trade as fungible product. A fungible batch in the Colonial system consists of 25,000 barrels or more of material from various suppliers, all of which meets the specifications published by the Pipeline company.

Furnace oil

A term ordinarily reserved for the kind of gasoil used for household heating. The quality of this product can vary from place to place. The USA, for instance, uses a lighter distillate for this purpose than do some European countries.

Futures

A type of contract established to pay today for something that will be delivered at a fixed future date.

Garbage Disposal Operations

Whereby the vessel lands a quantity of garbage for transfer to an approved garbage disposal location or facility ashore.

Garbled

Garbling was the prohibited practice of mixing rubbish with the cargo. A distorted, mixed up message was said to be garbled.

Gas Carrier

A specialised tanker built to comply with Marpol 73/78 Annex 1 and the appropriate IMO Code for Vessels Carrying Liquefied Gases in bulk.

Gas Free

This refers to a steady state ‘gas free’ condition, meaning the atmosphere in the tank is “safe for man-entry”. The most common value taken for ‘gas free’ is that the atmosphere is below the LEL (Lower Explosive Limit) and that sufficient oxygen is present. Maximum allowable concentrations of any toxins must also be taken into account.

Gas plant

Facilities, which remove liquids from natural gas streams, bear this name. So do processing units in refineries which fractionate the light ends distilled from crude or produced by cracking and other upgrading equipment. In both cases, the plant separates C3 and heavier materials from fuel gas. Some of this hardware cuts as deep as C2. Complex refineries usually have two gas plants. One, the saturates gas plant, handles paraffinic, straight run light ends. The other, the unsaturated gases plant, takes care of olefinic gas streams which come from crackers.

Gas to C4

An abbreviation for the percent mass of the hydrocarbon gases at normal temperature and pressure from C1 to C4 inclusive, present in crude oil.

GASBEND

Good And Safe (Port) Both ENDs

Gasoil

An intermediate distillate product used for diesel fuel, heating fuel and sometimes as feedstock.

Gasoil

A refined petroleum product denser than motor gasoline and kerosene but lighter than residual oil. This hydrocarbon mixture has two common uses: fuel for furnaces and for small diesel engines. It gets several popular names from these applications, including diesel and furnace oil. The phrase distillate fuel distinguishes gasoil from heavier mixtures used in large burners and large, slow diesel engines. The trade frequently shortens this term to distillate. ASTM's designation, No. 2 oil, serves as the primary name for gasoil in some parts of the world, especially North America. The refining industry employs "gasoil" To name certain intermediates in addition to familiar finished fuels. These special usages generally attach, or assume and adjective which indicates the source of the intermediate, such as atmospheric gasoil, vacuum gasoil, coker gasoil, pyrolysis gasoil, and so forth.

Gasoline

Also called gas or petrol, gasoline is a mixture of volatile, flammable liquid hydrocarbons derived from petroleum, with or without small quantities of additives, and used as motor fuel. It is also used as a solvent for oils and fats.

Gasoline extender

A component in motor gasoline blend added exclusively for volume. Ethanol, for example, often has this limited function in the USA.

Gateway

GE

Glycol Ether. Manufactured from either propylene oxide or ethylene oxide reacted with an alcohol. They are mainly used as solvents, plasticizers and brake fluids.

GEAR

A general term for ropes, blocks, tackle and other equipment

Geared Bulk Carriers

Typically in the handysize to handymax size range although there are a small number of geared panamax vessels, like all bulkers they feature a series of holds covered by prominent hatch covers. They have cranes, derricks or conveyors that allow them to load or discharge cargo in ports without shore-based equipment. This gives geared bulkers flexibility in the cargoes they can carry and the routes they can travel.

Gearless Carriers

Bulkers without cranes or conveyors. These ships depend on shore-based equipment at their ports of call for loading and discharging. They range across all sizes, the larger bulk carriers (VLOCs) can only dock at the largest ports, some of these are designed with a single port-to-port trade in mind. The use of gearless bulkers avoids the costs of installing, operating, and maintaining cranes.
