Measurement
There are two measurements of a merchant ship’s earning capacity which are of fundamental importance to its design and operation.These are deadweight and tonnage.Deadweight is related to the weight of cargo and tonnage is related to the volume of cargo.
The deadweight of a ship is the difference between the load displacement up to the minimum permitted freeboard and the light displacement.The lightweight comprises hull weight and machinery weight.Deadweight is therefore the weight of all cargo,oil bunkers,fresh and feed water,stores,crew and effects.The weight of the cargo alone is called the cargo deadweight.
A coefficient used in the early estimation of dimensions and in the study of economics is the ratio of deadweight to deep displacement,this is called the deadweight ratio or deadweight coefficient and normally refers to summer load draught.The deadweight coefficient for the parent ship will be a guide for the new design,since there is considerable variation in apparently similar ships,these should be treated with caution.
The volume of a ship is expressed in tons of 100 ft3 (2.83m3) and is referred to as its tonnage.On its tonnage are based the charges for berthing the ship,docking,passage through canals and locks,and for many other facilities.
There are two tonnages of primary interest no matter which authority is measuring or registering the ship.These are gross tonnage and register tonnage (net).The regulations governing their measurement are complicated but are summarized for the British Tonnage Regulations below.
The tonnage deck is the upper deck in vessels having one deck and the second deck in all other cases.Spaces above are 'tween decks and superstructures.
The underdeck tonnage is the total volume in tons of 100 ft3 of the ship below the tonnage deck to the inside of frames,underside of deck plating and above the inner bottom.This is obtained by detailed calculations,in a manner somewhat similar to that for displacement calculations and varies in detail for individual regulations; tonnage measured according to the tonnage regulations may,therefore,be slightly different from the actual volume of the spaces below the tonnage deck calculated for,say,cargo capacity.
The overdeck tonnage is the volume to the inside of frames and deck plating of the 'tween decks,poop,bridge,forecastle,deckhouses and erections above the tonnage deck less the exempted spaces.Spaces exempted include certain closed-in spaces associated with machinery,safety equipment,navigation,galleys,washrooms,water ballast and workshops.The gross tonnage is the sum of the underdeck and overdeck tonnages plus volumes of hatchways (less one-half per cent of gross tonnage computed without hatchways),plus light and air spaces which are included at the owner’s request in the measurement of the machinery spaces.
