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.

Charter Party

A written contract between the owner of a vessel and the person desiring to employ the vessel (char- terer); sets forth the terms of the arrangement, such as duration of agreement, freight rate and ports involved in the trip.

Charter, Bareboat

A charter where the owner provides his ship to the Charterer who then provides his own officers and crew and operates the vessel as if it were a unit of his own fleet. Hire is usually paid on a daily rate, monthly in advance, and the owner retains rights

Charter, Time

The chartering of a vessel for a fixed period of time with the vessel delivering and re-delivering at agreed dates and at agreed zones or places though usually with an option to the Charterer to extend the period of charter. It is really a contract for t

Charter, Trip

Chemical intermediate

A chemical intermediate is any substance generated by one step in a synthetic process and used for the succeeding step.

Chemical oxygen demand

When organic materials are not easily degraded by microorganisms, strong oxidizing agents (e.g., potassium permanganate) are used to enhance oxidation. COD is thus measured instead of BOD (see BOD). COD values will be larger than BOD values.

Chemical reaction

A chemical process in which substances are changed into different substances. Chemical reactions are manifested by the disappearance of properties characteristic of the starting materials and the appearance of new properties that distinguish the products. Examples of chemical reactions include burning of wood, fermentation of crops to make alcohol, tarnishing of silver, digestion of food and the synthesis of polystyrene plastics.

Chemical Refining

Refers particularly to the removal of free fatty acids by alkali. The alkali used is usually sodium hydroxide (caustic soda) or sodium carbonate (soda ash), either singly or in combination. One novel chemical refining technique uses aqueous ammonia as the alkali.

Chlorides

Chlorine-containing compounds. The oil trade pays most attention to these substances when discussing naphtha. Reformers need a specific amount of chloride on their catalyst to perform properly, any more or any less amounts to poison. Naphtha feedstock containing any significant amount of chlorides upsets the delicate balance and reduces reformat yield.

Chlorine

Chlorine, an inorganic chemical that can be obtained both naturally and synthetically, has a huge variety of uses, as a disinfectant and purifier, in plastics and polymers, solvents, agrochemicals and pharmaceuticals, as well as an intermediate in manufacturing other organic and inorganic substances. Chlorine is also used worldwide to purify water supplies as the ultimate defense against waterborne microbiological infection.

Chlorobenzene

A colorless, liquid organic compound used as a solvent and starting material for the manufacture of other organic compounds, such as phenol.

Chloroethylene

See Vinyl chloride monomer (VCM)

Chlorophyll

A natural, green colouring agent vital to a plant's photosynthesis process which is removed from vegetable oils through bleaching and refining processes.

Chock

A piece of wood or other material placed at the side of cargo to prevent rolling or moving sideways.

Chock-a-Block

Meaning something is filled to capacity or over loaded. If two blocks of rigging tackle were so hard together they couldn't be tightened further, it was said they were "Chock-a-Block".

Cholesterol

Cholesterol is one of a class of compounds known as sterols. It is an important component in animal tissues and cell membranes but found only in trace amounts in plant tissues. While many vegetable oils are known to contain traces of cholesterol, the amount is much less than in animal fats. Vegetable oils mainly contain other members of the sterol class.

CHOPT

Charterers Option (As opposed to owner's option)

Chromatography

Chromatography is a separation process used to analyse mixtures. The mixture, dissolved in a mobile phase, is contacted with a stationary phase, usually a fine powder. The components of the mixture are adsorbed or retained by the stationary phase to varying extents, depending on the degree of chemical affinity between them. Continual washing of the stationary phase with the original solvent or with a sequence of solvents, washes out the components of the mixture in turn. Various types of chromatography are used. Liquid chromatography involves passing a solution of the mixture through a column of solid adsorbent, or of an inert solid coated with a second immiscible liquid. Gas-liquid chromatography uses a gas as the mobile solvent and is usually carried out at a high temperature so that the components of the mixture are also gaseous. Thin layer chromatography is a form of liquid chromatography in which the solid adsorbent is formed in a thin layer on glass or other flat support.

In the 17th century the barriers that sailors laid across a ship’s deck in order to provide a safe haven from the enemy were called close-fights. By the mid 18th century that confined defensive space became called ‘close quarters’, i.e. close dwellings. This eventually came to mean ‘near enough to to be able to fight hand to hand’.
