During cargo loading operations it is important to ascertain the cargo weight loaded into
each individual cargo hold and the associated loading rate. Overloading the cargo hold
will increase the stress levels in the ship's structure. At high loading rate ports, where
there is no suitably positioned cargo weighing equipment, the ship's cargo officer should
request that the terminal stops loading to allow draught surveys and displacement
calculations to be performed to ensure compliance with the agreed loading plan.
An appropriately positioned cargo weighing device, which can provide continuously, or
at least at each step, an accurate indication of the weight of cargo that has been loaded
into each individual hold, is an important piece of equipment which can be used to avoid
overloading of individual cargo holds. Therefore, suitably
positioned weighing equipment should be installed at all terminals, especially those terminals
with high loading rates.
The weight of cargo loaded onboard a ship is normally determined from the ship's draughts and,
where fitted, shoreside weighing equipment.
Overloading of the ship's structure, can result from:
i) Inaccurate terminal weighing equipment providing incorrect data.
ii) The limited time available to check the draught and determine the load onboard especially at high
loading rate terminals.
iii) Loading cargo in a hold, in excessive of the allowable limit, to compensate for partial bunkers.
At some terminals the cargo weighing equipment is positioned at a location, remote from the
loading operating position. In such cases it is difficult for the officer in charge to determine how
much cargo has been loaded into a specific hold and this equipment may not provide the necessary
accurate information.
