Chapter 2 Flashcards
What does chapter 2 consist of
General cargo (break-bulk)
Who is responsible for cargo operations
Cargo operation is the responsibility of Chief Officer who discharges this duty under the Masters overall
control employing deck crew.
What is bale capacity
It is the cubic capacity of cargo space inside cargo battens, ceiling
and the underside of deck beams. In other words it is the volume of clear space
available inside the cargo hold without any obstructions.
What is grain capacity
It is the cubic capacity available for cargo that flows to the ship’s side.
What is block stowage
It is an even stack of cargo
which makes efficient use of available cargo space.
What is broken stowage
It is the amount of unused space due to the irregularity of shape of the cargo or cargo
space, or due to the inability to stow other cargo over the top. It is expressed as a percentage of total
space available.
What is bottom stow cargo
Cargo of high density
and/or ability to withstand crushing.
What is break-bulk
Non-bulk cargo which is neither
containerised nor unitised in some other way.
The handling carriage and stowage of
individual items.
What are cargo batten or spar ceilings
These are longitudinal timbers fitted to the
inside of ship’s frames to keep cargo
clear of the steel.
What is the ceiling
It is the timber placed along
the bottom of the cargo space to
protect the ship (usually tank tops)
from damage caused by cargo.
What is the CKD
Completely Knocked Down
machinery cargo, usually referring to
motor vehicles shipped in parts.
What is deadweight cargo
Cargo that occupies less than
1m3 per tonne weight. Freight is usually payable
on weight.
What is dunnage
It is material
(often timber or matting)
that is used to separate
or protect cargo. Where
dunnage is required, it
must be included in the
weight/space
calculations.
Types of dunnage examples
wood
inflatable bags
saw dust
paper
steel
8 uses of dunnage
- Protection of the ship
- Protection of the cargo
- Spread weight
- Separate cargo
- Separate cargo from moisture
- Provide additional friction to stop cargo shifting
- Fill areas of broken stowage and stop shifting
- Provide ventilation channels for the cargo
What is IBC
Intermediate bulk container (sometimes bulk bag) used for the carriage of between
0.25 and 3m3 of bulk material.
What is measurement cargo
Cargo on which freight is charged by space. It usually occupies more
than 1m3 of space per tonne weight.
What is optional cargo
Cargo for which the discharge port is not certain at the time of loading.
What is over-carried cargo
Cargo which has been carried beyond its intended
destination
What is over-stowed cargo
Cargo which is blocked by cargo for a later port of
discharge. Either requires double handling of offending cargo or must
be over-carried.
What is pre-slung cargo
Cargo which has lifting slings already attached.
What is short-shipped cargo
Cargo that has been booked but not loaded.
What is short-landed cargo
Cargo which was not discharged at its intended
destination.
What is the square of the hatch
It is an area of the hold or ‘tween deck directly below the hatch opening.
What is the stowage factor
It is the number of m3 occupied by 1 tonne of the cargo
What is the taint
A trace of a contaminating substance found in cargo that is likely to render it unfit for its intended purpose.
What is the tween-deck
A deck dividing vertically a cargo hold into compartments
What is transhipment
It is a transfer of cargo from one vessel to another (usually via
the wharf) for onward carriage.
What is the cargo stowage plan
is a diagrammatic representation of the cargo loaded or planned
to be loaded.
What is tomming
Timber used to brace cargo and prevent it from shifting.
The stowage plans serves a number of purposes including
- Advising the stevedores at the discharge ports of how the cargo on the cargo manifest is actually stowed
within the ship. This permits the planning of labour and machinery requirements in advance. - An important tool to assist the cargo watch-keepers (OOW) during cargo operation. Providing a record of
stowage for the use of ship’s officers when overseeing the loading or discharging - Proving the correct stowage in the event of cargo claims.
- Maintaining a record on board to assist in the planning of future stowages
What is sounding
is the measured height of
the fluid from the surface of the fluid
to the bottom of the tank.
What is ullage
is the void space in the tank
measured from the top of the tank to
the upper surface of the fluid. Ullage
is measured when the content of a
tank is highly viscous and if the tank
is filled to the maximum.
