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.

Conversion

Cracking molecules which boil above the threshold temperature into smaller ones which boil below it. Traditionally, the term applied to catalytic crackers. They convert oil which boils above 430 F to hydrocarbons which boil below that point. In other words, they convert gasoil to naphtha. The recent popularity of residue crackers has established another conversion standard around 720 F. This point marks the elevation of fuel oil to light products. Loosely, the term refers to any processing step which breaks molecules into pieces which boil at lower temperatures.

Conversion

In the plastics industry, conversion is the processing of raw materials into usable forms, e.g. the conversion of plastic pellets into films or the conversion of films into food containers. The steps involved include compounding (the mixing together of various raw materials, e.g. polymers and additives), melting and extruding, shaping and solidifying.

Convulsant

A material which causes seizures.

COOP

Copper-Bottomed

Copper-bottomed described ships that were fitted with copper plating on the underside of their hulls. The process was first used on ships of the British Navy in 1761 to defend their wooden planking against attack by Shipworms and to reduce infestations by barnacles. The method was successful in protecting ships’ timbers and in increasing speed and manoeuvrability and soon became widely used. Before long, "Copper-bottomed" began to be used figuratively to refer to anything that was certain and trustworthy.

Copra

The fruit of the tree ""Cocos Nucifera"" is the well known coconut. The white meat of the coconut, when removed and dried to between 4% to 7% moisture, is called copra. Drying may be either by sun drying where the moisture is allowed to evaporate naturally or forced drying where the heat for drying is obtained by burning the empty shells. This last method causes an uptake of PAH's in the oil making it necessary to bleach with active carbon.

Corn Oil

Corn oil is obtained from the germ of the corn (or maize) cob, the germ being separated as a byproduct from the manufacture of starch from corn. The corn oil is extracted from the germ and, after refining, it has a number of uses such as frying and as a good quality salad oil. It tends to be darker than refined rapeseed and soyabean oils and it may require dewaxing if it is used for bottling.

Corner Posts

Vertical frame components fitted at the corners of the container, integral to the corner fittings and connecting the roof and floor structures. Containers are lifted and secured in a stack using the castings at the ends.

Correspondent Bank

A bank that, in its own country, handles the business of a foreign bank.

Corrosion

Corrosion fatigue

Process involving conjoint corrosion and alternating straining of the metal, often leading to cracking

Corrosion product

Cottonseed Oil

Records show that cotton has been grown for nearly 3,000 years as a source of fibre to be spun and woven into textiles. The seed is a by-product which yields 20-24% of useful food oil.

Countervailing Duty

An additional duty imposed to offset export grants, bounties or subsidies paid to foreign suppliers in certain countries by the government of that country for the purpose of promoting export.

COW

Crude oil wash. A cleaning technique used by some ships. They spray a few tons of crude around their tanks to rinse off the remains of previous cargoes. This method cannot make a dirty vessel clean. But it can do enough good to prevent excessive darkening of not particularly color-sensitive cargo.

CPT

Carriage Paid To (named place of destination). The seller pays for carriage. Risk transfers to buyer upon handing goods over to the first carrier. Incoterms 2010

CPT (Carriage Paid To fro a named port)

A Term of Sale which means the seller pays the freight for the carriage of the goods to the named destination. The risk of loss of or damage to the goods, as well as any additional costs due to events occurring after the time the goods have been delivered to the carrier, is transferred from the seller to the buyer when the goods have been delivered into the custody of the carrier. If subsequent carriers are used for the carriage to the agreed upon destination, the risk passes when the goods have been delivered to the first carrier. The CPT term requires the seller to clear the goods for export.

CQD

Cracked

Broken by a thermal or catalytic process. This term frequently describes an oil product which contains cracked components made by such a process.

Cracked component

An ingredient in a hydrocarbon blend produced by a cracking process. The opposite of a virgin or straight-run component. Blends containing any cracked components do not qualify as straight-run. The presence of cracked components makes refinery streams unsuited for certain feedstock uses. The issue arises most frequently regarding heavy fuel oils. Companies buying such streams to produce catfeed want a virgin material containing no cracked components.

Cracked cutters

Cycle oils used to reduce the sulfur content or, especially, the viscosity of fuel oil.

Cracked fuel

Fuel oil containing molecules broken in a cracking unit. The term most frequently applies to residue. It distinguishes streams unsuitable for upgrading from straight-run material of interest as feedstock.

Cracked Gas

see UNSATURATED GASES

Cracked naphtha

General term for any naphtha-range fraction produced by a molecule breaking process. The category includes cat gasoline from a catalytic cracker, visbroken naphtha from a visbreaker, and coker naphtha from a coking unit. In ordinary usage, this term signifies streams with a high olefin content. That custom discourages its application to hydrocrackate and pyrolysis gasoline, known, respectively, for their naphthenes and aromatics concentrations.

Cracked Stock

see CRACKED COMPONENT. Cracking units produce cracked stocks such as cycle oils and cat naphthas used for blending finished products.

Cracker

A processing unit which breaks molecular bonds, usually to produce lighter hydrocarbons with lower boiling points. Commercial crackers (cracking units) include cat crackers, hydrocrackers, thermal crackers, visbreakers, and stream crackers.

Cracking

The process of breaking down large molecules of oil into smaller ones. When this process is achieved by the application of heat only, it is known as thermal cracking. If a catalyst is used as well it is known as catalytic cracking. It is known as hydrocracking if the catalytic process is conducted in a hydrogen atmosphere. Cracking causes molecular decomposition and recombination to produce a range of more useful base chemicals.

Cracking-Cracker

The process of breaking down large molecules of oil into smaller ones. When this process is achieved by the application of heat only, it is known as thermal cracking. If a catalyst is used as well it is known as catalytic cracking. Cracking causes molecular decomposition and recombination to produce a range of more useful base chemicals. Cracking is the basic process taking place in crackers.
