One T.E.U., or 20-foot equivalent unit, represents the volume of one 20-foot container, though ships can carry containers of varying sizes." * Technical note: initial SVG code was automatically generated by the "Variable-width bar charts" spreadsheet linked at User:RCraig09/Excel to XML for SVG .
A merchant ship, merchant vessel, trading vessel, or merchantman is a watercraft that transports cargo or carries passengers for hire. This is in contrast to pleasure craft , which are used for personal recreation, and naval ships , which are used for military purposes.
Lightweight displacement – LWD – The weight or mass of the ship excluding cargo, fuel, ballast, stores, passengers, and crew, but with water in the boilers to steaming level. Loadline displacement – The weight or mass of the ship loaded to the load line or plimsoll mark. Deadweight tonnage (DWT) is a measure of how much weight a ship can ...

Compared to today's largest container ships, Maersk Line's 15,200 TEU Emma Mærsk-type series, a 20,000 TEU container ship would only be moderately larger in terms of exterior dimensions. According to a 2011 estimate, an ultra-large container ship of 20,250 TEU would measure 440 m × 59 m (1,444 ft × 194 ft), compared to 397.71 m × 56.40 m ...
This is a list of container ships with a capacity larger than 20,000 twenty-foot equivalent units (TEU). Container ships have been built in increasingly larger sizes to take advantage of economies of scale and reduce expense as part of intermodal freight transport. Container ships are also subject to certain limitations in size. Primarily ...
Cargo ships are usually specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel , and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped.
For a given tonnage, the second factor which governs the ship's dimensions is the size of the ports and waterways it will travel to. For example, a vessel that will pass the Panama Canal will be limited in its beam and draft. For most designs, the ratio of length-to-width ranges between 5 and 7, with an average of 6.2. [4]
