Cargo delivered to/from the carrier where origin/destination of the cargo is in the local area.

Adverse effects seen at the site where the test material comes into initial contact with the organism.

Corrosion preferentially concentrated on discrete sites of the metal surface exposed to the corrosive environment

A deal in which companies trade oil in one place for some somewhere else.

a device for raising and lowering boats from one water level to another. It is often associated with a dam.

Tows must navigate through locks in order to get around dams on the rivers. Many locks on the nation's waterways are now over 60 years old and are too small to accommodate the size of the modern tows, forcing those tows to be broken up and taken through the lock piecemeal. Since this affects the industry's efficiency and safety, the towing industry is asking Congress to approve locks modernization projects. The industry pays half the cost of modernization through a fuel tax.

A vessel equipped to transport logs discharge them into the water by tipping itself

One disappearing but fascinating function of the towing industry is log towing, where small boats pull logs on rivers to sawmills in log rafts, frames of logs connected with chains within which are hundreds of logs. Today, this operation is only performed in the Pacific Northwest.

In old warships, the muzzle-loading cannon were charged with black powder of uncertain potency that would propel the iron shot an equally uncertain distance with doubtful accuracy. A 24-pounder long gun, for instance, was considered to have a maximum effective range of 1200 yards, even though, under the right conditions, a ball might travel some 3000 yards. Similarly, a short, stubby 32-pounder carronade’s lethality faded fast beyond 400 yards. Thus, the odds were against a hit when one fired a long shot.

This refers to a widely used system by which the colour of an oil can be measured. The essential features of this system consist of a light source, a series of calibrated coloured glasses forming the standards of reference and an instrument in which they can be matched against the oil. The colour scale consists of three series of coloured glasses - red, yellow and blue. These glasses are moved into position against the sample viewed until a match is obtained. This removal method is now becoming obsolete since a fully automated Lovibond meter was developed. The method was first developed by Mr Lovibond for the measurement of the colour of beer at his brewery in Salisbury, England in the Eighteenth Century and has been traditionally used for oil colours.

Last open water

A description of distillate or residual fuel oils, which flow at relatively low temperatures. Sometimes, the industry uses this term, and its opposite, informally. Frequently, though, it designates oil meeting specific standards of a particular market.

Very powerful, heavy-duty diesel engines such as those used to drive ocean-going ships and large electricity generators.These engines burn residual oil.

A trailer or semi–trailer with no sides and with the floor of the unit close to the ground.

Liquefied Petroleum Gas: A nonrenewable gaseous fossil fuel, which turns to liquid under moderate pressure;by-product of natural gas processing and oil refining

Liquified petroleum gas. Propane and butane captured as by-products of natural gas and crude oil processing.

A self propelled tanker barge for the bulk carriage of Liquefied Petroleum Gas

Tankers fitted to transport such volatile products as propane, butane, ammonia, and vinyl chloride monomer. These cargoes require high-pressure or refrigerated storage to keep them in liquid form. In these times of slack employment in their specialty, some of these tankers haul low-density clean products such as natural gasoline and naphtha. A few LPG carriers equipped with unusually powerful cooling systems can transport ethylene.

A non propelled tank barge for the carriage of LPG

A tanker for the bulk carriage of Liquefied Petroleum Gas in insulated tanks, which may be independent or integral. The cargo is pressurised (smaller vessels), refrigerated (larger vessels) or both ('semi-pressurised') to achieve liquefaction.

An LPG tanker additionally capable of the carriage of chemical products as defined in the International Bulk Chemical Code

AFRA's large-range 2 tankers. These vessels have deadweight tonnages between 80,000 and 159,999.

Long Range 1 (LR1) Tanker - Product tanker ranging in size between 45,000 and 79,999 deadweight tonnes. Main trade routes are Middle East Gulf to the Far East and Europe, or from northwest Europe to the United States.

Long Range 2 (LR2) Tanker - Product tanker ranging in size from 80,000 to 159,999 deadweight tonnes. Main trade routes are Middle East Gulf to the Far East and Europe, or from northwest Europe to the United States. The LR2 segment consists of the largest product tankers. The LR2 tankers usually transport “clean products” on the long distances from the Middle East to countries in Asia or Northern Europe. The LR2 tankers mainly transport “dirty products” on the long or intermediate distances out of the Black Sea to the Mediterranean or to the USA, or from the Baltic or the North Sea to Northern Europe or the USA.

A price for oil transportation quoted as a total for the cargo. This approach differs from the popular practice of charging a rate per ton carried. Lumpsums also differ from the rate method by including canal tolls and other items usually treated as surcharges.
