WHAT IS THE STOWAGE FACTOR ?!
In
shipping, the stowage factor indicates how many cubic metres
of space one metric tonne (or cubic feet of space one long ton) of a particular
type of cargo occupies in a hold of a cargo ship.
It is calculated as the ratio of the stowage space
required under normal conditions, including the stowage losses caused by the
means of transportation and packaging, to the weight of the cargo.The stowage
factor can be used in ship design and as a reference to evaluate
the efficiency of use of the cargo space on a ship.
The
stowage factor varies from one type of commodity to another — for example iron ore has
a stowage factor of 0.40 (m3/mt), meaning that the space needed by one tonne of ore is
only one sixth of that required to stow one tonne of woodchips that
have a stowage factor of 2.5. This means that if a ship designed to carry
woodchips is loaded with iron ore, only a small part of the hold capacity can
be utilized, and a bulk carrier designed to carry iron ore
cannot be loaded to the maximum draft with
woodchips, leaving much of its deadweight tonnage unutilized. Thus the
stowage factor is taken into account in ship design when determining the size
of cargo holds, and specialized ships such as ore carriers and car carriersare
built for cargoes with a stowage factor that departs significantly from the
average.
The
stowage factor also depends on the type of packaging,
being the lowest for unpackaged bulk cargo.
While most commonly used for dry bulk cargo, a stowage factor can also be
calculated for liquid bulk cargo and other commodities such as containers or cars.
Stowage factors for several types of cargo are presented in the following
table.
