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.

Ship’s Tackle

All rigging, cranes, etc., utilized on a ship to load or unload cargo.

Shipment

The tender of one lot of cargo at one time from one shipper to one consignee on one bill of lading.

Shipper

The person or company who is usually the supplier or owner of commodities shipped. Also called Consignor.

Shipper’s Export Declaration – SED, “Ex Dec”

A joint Bureau of the Census’ International Trade Administration form used for compiling U.S. ex- ports. It is completed by a shipper and shows the value, weight, destination, etc., of export shipments as well as Schedule B commodity code.

Shipper’s Instructions

Shipper’s communication(s) to its agent and/or directly to the international water–carrier. Instructions may be varied, e.g., specific details/clauses to be printed on the B/L, directions for cargo pickup and delivery.

Shipper’s Letter of Instructions for issuing an Air Waybill

The document required by the carrier or freight forwarders to obtain (besides the data needed) authorization to issue and sign the air waybill in the name of the shipper.

Shipper’s Load & Count (SL&C)

Shipments loaded and sealed by shippers and not checked or verified by the carriers.

Shippers Association

A non–profit entity that represents the interests of a number of shippers. The main focus of shippers associations is to pool the cargo volumes of members to leverage the most favorable service contract rate levels.

Shipping Act of 1916

The act of the U.S. Congress (1916) that created the U.S. Shipping Board to develop water transporta- tion, operate the merchant ships owned by the government, and regulate the water carriers engaged in commerce under the flag of the United States. As of June 18, 1984, applies only to domestic offshore ocean transport.

Shipping Act of 1984

Effective June 18, 1984, describes the law covering water transportation in the U.S. foreign trade.

Shipping Act of 1998

Amends the Act of 1984 to provide for confidential service contracts and other items.

Shipping Order

SHMT

Shop Primer

A thin coating that is applied to new steel in a newbuilding shipyard to protect it from corrosion during the building process

Shopping Complex

A vessel adapted for uses as a shopping complex

Shore

A prop or support placed against or beneath anything to prevent sinking or sagging.

shore tank figures

Quality data on a shipment derived from storage tank samples taken prior to loading or quantity determination based on storage depletion in the course of loading. Shore tank gauging could also give useful information on the quantity of oil discharged into a receiver's terminal. The industry ordinarily tests discharge (often called outturn) quality of unloaded oil before it moves ashore. These data come from unloading line or ship's composite samples. Suppliers and receivers often use shore figures to verify or dispute ship's figures.

Short Sea Shipping – SSS (European-EU)

Short Sea Shipping means the movement of cargo by sea between ports situated in geographical Eu- rope or between those ports situated in non-European countries having a coastline on the enclosed seas bordering Europe (Baltic, Mediterranean and Black). It is a successful mode of transport in Eu- rope.

Short Ton (ST)

A weight unit of measure equal to 2,000 pounds.

Shortening

Anhydrous fats used in the bakery industry, catering trade and also in domestic kitchens. Plasticity is imparted to these products by texturisation of the feed stock (generally blends of two or more oils and fats) in scraped surface tube coolers to produce small crystals enmeshing liquid oil in a crystalline network. In some cases, gas is also incorporated to improve their plasticity. Animal fats, being solid fats, were the first materials used for making shortenings. Compound shortenings using liquid oil and oleo-stearin from animal fats replaced 100% animal fat-based shortening. Hydrogenation of oils enabled the manufacturer to replace animal fat with hydrogenated oil and develop shortenings based on 100% vegetable oils/fats. Shortenings are formulated and produced to satisfy specific markets and users requirements and therefore show a wide variation in physical properties. The following types of shortenings can be listed - a. bakery shortenings (e.g. plastic shortenings, high ratio cake shortenings and liquid shortenings). b. industrial shortenings for the catering trade, and c. domestic shortenings.

Slip Point

Fats consist of a complex mixture of glycerides and therefore do not have sharp melting points, unlike pure chemical substances. The slip point of a fat is the temperature at which a column of fat in an open capillary tube moves up the tube when it is subjected to controlled heating in a waterbath. Because of their polymorphic behaviour, the slip point of some fats is dependent on the previous temperature treatment, i.e. tempering of the sample and, therefore, not very reliable analysis.

Slop tanks

A tank utilized to store the COW medium and receipt of tank washings.

This historical state is called "statement of facts" or "port log" and serves as the basis for the drawing of the "time sheet" used for the calculating of the laytime and demurrage and possibly despatch money. The officer on board must record all information related to the loading or discharging *working hours, interruptions of loading and/or discharging) in the ship's log book or in a special workbook.

Solid Fat Content

Fats such as butter, margarine, bakery shortening, beef tallow and cocoa butter appear to be solid but are, in fact, a mixture of solid and liquid components. The proportion of solid present at various temperatures of use is often of interest in relation to the function to be performed, for example, the spreading of butter on bread. A simple and rapid measurement of the solid fat content (SFC) can be obtained by the use of a nuclear magnetic resonance (NMR) instrument. The measurement depends on the fact that the protons of the combined hydrogen atoms of fat in the liquid state are more mobile than those of the fat in the solid state. The mobile protons are therefore more responsive to a magnetic field and this fact can be used to measure the proportion of liquid fat present. The method is superseding the dilation procedure.

Solubility

The extent to which a substance mixes with a liquid to produce a solution

Solvent

A solvent is a liquid that has the ability to dissolve, suspend or extract other materials, without chemical change to the material or solvent. Solvents make it possible to process, apply, clean or separate materials. Water is an inorganic solvent. Organic solvents include hydrocarbon solvents, oxygenated solvents and chlorinated solvents.

Solvent Extraction

A process which usually uses hexane as a solvent to extract oil from oil-bearing materials. The residual oil left in extracted soyabean flakes or meal can be reduced to one percent or less. In the United States, nearly all soyabeans are processed by solvent extraction. A substantial part of cottonseed, flaxseed and other oilseeds is handled by this method.

SOM

Son of a Gun

When in port, and with the crew restricted to the ship for any extended period of time, wives and ladies of easy virtue often were allowed to live aboard along with the crew. Infrequently, but not uncommonly, children were born aboard, and a convenient place for this was between guns on the gun deck. If the child's father was unknown, they were entered in the ship's log as "son of a gun".
