Archimedes' principle
“A ship displaces
a weight of water that is
equal to its own weight.”
Слайд 3a vessel will experience an upthrust that is equal to the
weight of the
displaced water.

Displacement
The weight of a vessel and her contents,
or
the weight of the displaced watermass.
Слайд 7Net tonnage can be calculated by deducting the spaces that are
not used for cargo from the gross tonnage.

Net tonnage
Слайд 8Harbour dues are usually calculated according to the gross tonnage, but
some ports use the vessel’s net tonnage.

By deadweight is understood the weight of the vessel’s contents:
cargo - bunkers - ( fuel / lubricating oil / ballast water / fresh water/ potable water) equipment - stores.

By Oil Space is understood 98% of the total volume of
the wet bulk tanks.
Cargo Carrying Capacity
Ullage – the free space above the liquid in a tank, which is measured in metres or feet.

“Length over all” (L.O.A.)
is the total length of the vessel.
