What is a tonnage survey?
The Tonnage Survey is a short survey conducted with the vessel ashore or afloat. Some key details of the vessel and key measurements are taken and submitted to the RYA for onward submission to the Register of Shipping & Seamen. All fees are set by the RYA & YDSA and available on their website.
How do you measure tonnage?
Tonnage, in shipping, the total number of tons registered or carried or the total carrying capacity. Gross tonnage is calculated from the formula GT = K1V, where V is the volume of a ship’s enclosed spaces in cubic metres and K1 is a constant calculated by K1 = 0.2 + 0.02 log10 V.
What is the rule of tonnage?
Law of Gross Tonnage The law, which is more common sense then explicitly written in the code, goes like this: “The heavier vessel always has the right-of-way.” This is based on simple Newtonian physics. Newton’s first law talks about objects in motion stay in motion unless another force is acted upon it.
What is a tonnage system?
It indicates a vessel’s earning space and is a function of the moulded volume of all cargo spaces of the ship. A commonly defined measurement system is important, since a ship’s registration fee, harbour dues, safety and manning rules, and the like may be based on its gross tonnage (GT) or net tonnage (NT).
How is ship tonnage determined?
Gross Tonnage is a measure of the ships total interior volume and is calculated by multiplying the interior volume “V” of the ship in cubic meters by a variable known as “K” (which varies depending on the ships overall volume).
What is NRT shipping?
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 deadweight tonnage of a ship?
Deadweight tonnage is a measurement of total contents of a ship including cargo, fuel, crew, passengers, food, and water aside from boiler water. It is expressed in long tons of 2,240 pounds (1,016.0469088 kilograms).
How do you calculate mining tonnage?
The standard method of making these estimates is to find the cubic contents of triangular prisms, in the apexes of which the drill holes are placed, by multiplying the surface area by the average depth of the ore in the three drill holes and then multiplying the cubic contents by the specific gravity of the ore or rock …

What is NRT full form?
