A single, standard barge can hold 1,500 tons of cargo or as much as either 15 railroad cars or 60 trucks can carry. A barge is 200 feet long, 35 feet wide and has a draft of 9 feet. Barges carry dry bulk (grain, coal, lumber, gravel, etc.) and liquid bulk (petroleum, vegetable oils, molasses, etc).

Most such cranes operate on rail tracks and have articulating rail trucks on each of their four legs, enabling them to traverse along the terminal and work various bays on the vessel and for more than one crane to work a single vessel simultaneously. Most terminals have direct rail access and container storage areas, and are served by highway carriers.
Containerization: The technique of using a container to store, protect and handle cargo while it is in transit. This shipping method has both greatly expedited the speed at which cargo is moved from origin to destination and lowered shipping costs.

I.L.W.U.– International Longshore and Warehouse Union, which operates on the West Coast. See labor unions and longshoremen.
Intermodal Shipment: When more than one mode of transportation is used to ship cargo from origin to destination, it is called intermodal transportation. For example, boxes of hot sauce from Louisiana are stuffed into metal boxes called containers at the factory. That container is put onto a truck chassis (or a railroad flat car) and moved to a port. There the container is lifted off the vehicle and lifted onto a ship. At the receiving port, the process is reversed. Intermodal transportation uses few laborers and speeds up the delivery time.

Some laborers don’t belong to a union.
Landlord Port: At a landlord port, the port authority builds the wharves, which it then rents or leases to a terminal operator (usually a stevedoring company). The operator invests in cargo-handling equipment (forklifts, cranes, etc), hires longshore laborers to operate such lift machinery and negotiates contracts with ocean carriers (steamship services) to handle the unloading and loading of ship cargoes. (See also: operating port.)
LASH: These 900-foot-long ships carry small barges inside the vessel. LASH stands for Lighter Aboard Ship. Just as cargo is transported by barge from the shallower parts of the Mississippi River to the Port of New Orleans for export aboard ocean-going ships, LASH barges are lifted into these unusual ships. Overseas, the ship can discharge clusters of barges in the open waters. Then several towboats will assemble the barges into tows bound for various ports and inland waterways, without the ship having to spend time traveling to each port.

Steamship Agent: The local representative who acts as a liaison among ship owners, local port authorities, terminals and supply/service companies. An agent handles all details for getting the ship into port; having it unloaded and loaded; inspected and out to sea quickly. An agent arranges for pilots; tug services; stevedores; inspections, etc., as well as, seeing that a ship is supplied with food, water, mail, medical services, etc. A steamship agency does not own the ship.

A terminal operator oversees unloading cargo from ship to dock, checking the quantity of cargoes versus the ship’s manifest (list of goods), transferring of the cargo into the shed, checking documents authorizing a trucker to pick up cargo, overseeing the loading/unloading of railroad cars, etc.
Toplift: A piece of equipment similar to a forklift that lifts from above rather than below. Used to handle containers in the storage yard to and from storage stacks, trucks and railcars.
Towboat: A snub-nosed boat with push knees used for pushing barges. A small towboat (called a push boat) may push one or two barges around the harbor. A large towboat is used to push from 5 to 40 barges in a tow is called a line boat. From the Port of New Orleans, line boats deliver cargo to Mid-America via the 14,500-mile waterway system flowing through the Crescent City.
(See also tug boat)
Tractor-Trailer: Some trucks are a solid unit, such as a van, but many have three main units. The front section where the driver sits is called the cab or the tractor (because it pulls a load). Cargo is loaded into the metal box (container), which is loaded onto the wheel base called a chassis or a trailer. These big trucks are often also called 18-wheelers.
Trailer On Flat Car (TOFC): A container placed on a chassis that is in turn placed on a railroad car.
Tramp: A ship operating with no fixed route or published schedule.
Transit Port: When the majority of cargoes moving through a port aren’t coming from or destined for the local market, the port is called a transit (or through) port.

Trucks: Heavy automotive vehicles used to transport cargo. In the maritime industry, cargo is often carried by tractor-trailers. The tractor is the front part of the vehicle, also called a cab. The trailer is the detachable wheeled chassis behind the tractor, on which containers or other cargoes are placed. (See: common carrier; heavy hauler; drayage)
Tugboat: Strong v-hull shaped boat used for maneuvering ships into and out of port and to carry supplies. A ship is too powerful to pull up to the wharf on its own. It cuts power and lets the tug nudge it in. Generally barges are pushed by towboats, not tugs.
