Nautical Terms That begin with the Letter T

Tack
To tack, or tacking, is the act of zig zagging a sailing boat through the wind so that it blows on opposite sides of the sails, firstly on one side and then on the other.

Tank Barge
A tank barge is used for the inland transportation of liquids such as chemicals, petroleum, vegetable oils, liquefied gasses and even molasses.

Tank Cleaning
The act of thoroughly cleaning a tank to rid it of all traces of its former cargo. Tank cleaning is usually done using high-pressure water jets

Tanker
A tanker is a type of bulk carrier that has been designed for the transportation of liquid cargo. Tankers may be oil tankers or chemical tankers and usually carry petroleum products.

They vary hugely in size from small vessels that travel along coastlines to enormous VLCCs - Very Large Crude Carriers.

Technical Manager
The Technical Manager is a company or person who is responsible for managing the crewing, maintenance and insurance of a vessel.

Terminal
Also sometimes called a wharf, the terminal is the place where cargo and shipping containers are handled. Vessels dock at the terminal to load and offload their cargo or containers.

Terminal Operator
The terminal operator is the company that handles activities related to cargo at a terminal. They supervise the unloading of cargo from the vessel to the dock and check the quantity of cargo is in line with what is listed on the manifest (list of cargo).

They also check that all documents are in order, transfer the cargo into storage sheds, arrange for a logistics company to pick up cargo, and oversee the loading and unloading of railroad cars.

TEU
Twenty Foot Equivalent Unit (TEU) is used to describe the storage capacity of a container ship. A TEU is a unit of measure unique to the maritime industry.

It is equal to the space taken by a twenty foot shipping container. For example, if a container is forty feet long, it measures two TEUs.

Through Port
A through port deals with cargo that is not coming from, or intended for, the local market. Through ports are sometimes also called transit ports. It is more-or-less the opposite of a captive cargo port.

Tonnage
Tonnage can either mean the weight in tons of cargo or the size or carrying capacity of a vessel measured in tons.

Toplift
A toplift is similar to a forklift although it lifts shipping containers from above as opposed to from underneath. It moves containers at a terminal to and from storage stacks, railcars and trucks for onward transportation by land or sea.

Towage
Towage can either refer to the charge for the service of a tugboat for assisting a vessel or the act of towing a ship or other objects from one point to another.

Towboat
A towboat, also called a pusher, pusher tug, or pusher boat, is a small but strong boat with a snub-nose shaped hull that is used to push barges in, out and around harbors.

Smaller towboats are usually limited to pushing one or two barges, while larger boats (also known as a lone boat) can push anywhere from five barges up to forty.

Tramp
A tramp is a vessel that operates on an ad-hoc basis and has no published schedule or fixed routes.

Transhipment
Transhipment is used to refer to the unloading of cargo at a port or other location where it is then reloaded, possibly into another mode of transportation, for transfer to its final destination.

Transit Shed
A transit shed is a shed on a wharf which is meant for short term use to protect cargo from the weather.

Transtainer
A transtainer is a type of large motorized crane that has rubber tires and can straddle up to six railway tracks. A transtainer can lift up to 35 tons and is used for loading and unloading shipping containers to and from railway cars.

Tugboat
A tugboat or tug is a small but strong boat with a V-shaped hull that is used to maneuver vessels in and out of ports.

Large vessels such as container ships are too powerful to approach the dock under their own steam so they will cut their engines and allow the tug to pull and push them into position. Tugs are also used to carry supplies to other vessels.

Twenty Foot Equivalent Unit (TEU)
Twenty Foot Equivalent Unit (TEU) is used to describe the storage capacity of a container ship.

A TEU is a unit of measure unique to the maritime industry. It is equal to the space taken by a twenty foot shipping container. For example, if a container is forty feet long, it measures two TEUs.
