Shaft Horsepower (SHP) – The amount of mechanical power delivered by the engine to a propeller shaft. One horsepower is equivalent to 746 Watts. Tonnage – a number derived from any of several methods to calculate the volume or other number indicative of a ship's cargo carrying capacity. Gross tonnage – GT – Not expressible in units of ...
Tonnage is a measure of the capacity of a ship, and is commonly used to assess fees on commercial shipping. The term derives from the taxation paid on tuns or casks of wine. In modern maritime usage, "tonnage" specifically refers to a calculation of the volume or cargo volume of a ship.
The combined deadweight tonnage of container ships and general cargo ships, which also often carry containers, represents 21.8% of the world's fleet. [ 58 ] As of 2009 [update] , the average age of container ships worldwide was 10.6 years, making them the youngest general vessel type, followed by bulk carriers at 16.6 years, oil tankers at 17 ...
Gross tonnage. Gross tonnage is calculated by measuring a ship's volume (from keel to funnel, to the outside of the hull framing) and applying a mathematical formula. Gross tonnage (GT, G.T. or gt) is a nonlinear measure of a ship's overall internal volume. Gross tonnage is different from gross register tonnage. [ 1 ]
List of large sailing vessels. This is a list of large sailing vessels, past and present, including sailing mega yachts, tall ships, sailing cruise ships, and large sailing military ships. It is sorted by overall length. The list, which is in the form of a table, covers vessels greater than about 200 feet (61 m) LOA, which includes overhangs ...
Loaded displacement is the weight of the ship including cargo, passengers, fuel, water, stores, dunnage and such other items necessary for use on a voyage. These bring the ship down to its "load draft". [ 8 ] Full load displacement and loaded displacement have almost identical definitions. Full load is defined as the displacement of a vessel ...
Depending on design requirements, some ships have extremely large internal volumes in order to serve their duties. Gross tonnage is a monotonic and 1-to-1 function of the ship's internal structural volume. It does not include removable objects placed outside the deck or superstructure, like the shipping containers of a container ship.
The world's longest ships are listed according to their overall length (LOA), which is the maximum length of the vessel measured between the extreme points in fore and aft. In addition, the ships' deadweight tonnage (DWT) and/or gross tonnage (GT) are presented as they are often used to describe the size of a vessel. The ships are listed by type.
