Are deadweight DWT and gross tonnage GRT the same?

Are deadweight DWT and gross tonnage GRT the same?

Deadweight Tonnage: expresses the number of tons of 2,240 pounds that a vessel can transport of cargo, stores, and bunker fuel. Gross Tonnage: applies to vessels, not to cargo. It is determined by dividing by 100 the contents, in cubic feet, of the vessel’s closed-in spaces. A vessel ton is 100 cubic feet.

What is difference between gross tonnage and deadweight?

How do you calculate dead weight tonnage?

To calculate the Deadweight tonnage figure, take the weight of a vessel that is not loaded with cargo and subtract that figure from the weight of the vessel loaded to the point where it is immersed to the maximum safe depth.

What is difference between GRT and NRT?

Gross register tonnage or gross tonnage (GT) represents the total internal volume of cargo vessels. Gross register tonnage (GRT) and net register tonnage (NRT) have been replaced by gross tonnage (GT) and net tonnage (NT) which express the size and volume of a ship as a simple dimensionless figure.

What is Net register tonnage of a ship?

Net register tonnage (NRT, nrt, n.r.t.) is a ship’s cargo volume capacity expressed in “register tons”, one of which equals to a volume of 100 cubic feet (2.83 m3). Net tonnage is thus used in situations where a vessel’s earning capacity is important, rather than its mere size.

What is the meaning of gross tonnage?

Gross tonnage is deduced from the volume of all the spaces of the ship contained within the hull, bulkheads and decks, in accordance with the 1969 International Convention on Tonnage Measurement of Ships. It is expressed by a figure without units.

What is the gross registered tonnage of a ship?

GRT is an INTERNAL VOLUME measurement of your vessel based on the dimensions of your vessel, such as Length, Breadth, and “depth” (not draft). The initials for this system are “GT” and you may also see this tonnage listed on a vessels COD or COI if it is measured under this system.

What is the difference between gross tonnage and dead weight?

What is net tonnage (NT)?

Net Tonnage, Gross Tonnage, Light Ship or Light Weight and Dead Weight tonnage – Net tonnage (NT) is based on a calculation of the volume of all cargo spaces of the ship. It indicates a vessel’s earning space and is a function of the moulded volume of all cargo spaces of the ship.
