Cargo Handling Terms

Deadweight cargo: cargo on which freight is usually charged on its weight
Dunnage: timber boards used to keep the surface of the cargo off the steel deck plate, provides air space around the cargo
Flemish Eye: a reduced eye made of three strands, spliced into the end of a cargo runner
Flemish hook: a large hook used in conjunction with the lower purchase block in the rigging of a heavy-lift derrick
Floodable length: the maximum length of a compartment that can be flooded to bring a damaged vessel to float at a waterline

Freight and Cargo

Freight: the monetary charge levied for the carriage of cargo
Grain capacity: the cubic capacity of a cargo space when the length, breadth, and depth are measured from the inside of the ship's shell plating
Gross tonnage: the total internal capacity of the ship

Slings and Lifting

Wire bridle slings: used for lifting cargo
Rope slings: versatile slinging arrangements employed in the movement of general cargo parcels
Canvas wheel slings: used for lifting cargo
Board and canvas slings: specialized for bagged cargo or sacks

Cargo Handling and Stowage

Advantages of palletization: less handling of cargo, less cargo damage, and faster loading/discharge times
Pallet transporters: used for 'stuffing' containers
Fork lift trucks: used for moving cargo parcels and palletized goods

Hatchwork and Heavy-Lift Cargoes

Changes in cargo transportation: design and structure of cargo holds changing to meet modern shipping needs
Hold structures: trending towards square corners to reduce broken stowage and suit palletization and fork lift truck use
Specialist cargoes: such as steel coils, case goods, and castings, require conventional holds and stowage
