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.

Polyol

This is an organic molecule with three or more alcohol groups attached. The correct chemical term for an alcohol group is a hydroxy group with the combination of one oxygen attached to one hydrogen (OH).

Polyolefin

The collective name given to those polymers that are made from the lower olefins: ethylene, propylene, butylene and isoprene. The polyolefins are thermoplastic polymers.

Polypropylene

Any of various thermoplastic plastics or fibers that are polymers of propylene. Polypropylene can be made into fibers, where it is a major constituent in fabrics for home furnishings such as upholstery and carpets. Numerous industrial end uses include rope and cordage, disposable non-woven fabrics for diapers and medical applications. As a plastic, polypropylene is moulded into bottles for foods and personal care products, appliance housings, dishwasher-proof food containers, toys, automobile battery casings, and outdoor furniture.

PONA

A breakdown of the kind of molecules which compose a hydrocarbon mixture. The trade uses PONA most frequently to describe naphthas. See paraffins, olefins, naphthenes, and aromatics. All hydrocarbons fall into one of these four categories. The feedstock trade characterizes naphthas by what percentage of each kind of molecule they contain. A PONA test determines the composition of a particular cargo or stream.

Pontoon (Function Unknown)

Basic oleochemicals are producted primarily through splitting, distillation, fractionation, separation, hydrogenation, methylation and hydrophilisation. Derivatives of basic oleochemicals are produced mainly through amidation, chlorination, dimerisation, epoxidation, ethoxylation, quarternisation, sulfation, sulfonation, transesterification and saponification.

Producers

Companies, often state organizations, which own oil wells and the crude which flows from them. This category includes a large number of private enterprises. Integrated oil companies and specialists called independent producers develop much of the world's crude supply. But, as a matter of custom, the industry tends to think not of them but of oil exporting nations when speaking of producers. Other names, such as equity holders, leaseholders, or even equity producers, distinguish these private, commercial organizations. They need a separate category because they must buy the oil they develop, through lease fees, royalties, cash, production sharing, or other arrangements, from whoever has sovereign right to it.

Product

Propane

A colorless, gaseous hydrocarbon. It is separated in large quantities from natural gas, light crude oil, and oil-refinery gases and is commercially available as liquefied propane or as a major constituent of liquefied petroleum gas (LPG). As with ethane, propane is an important raw material for the ethylene petrochemical industry. The decomposition of propane in hot tubes to form ethylene also yields another important product, propylene.
