Cargo Work | Definitions

Air draught – means the vertical distance from the surface of the water to the highest point of the ship’s mast or aerial.


Bale space capacity – is that cubic capacity of a cargo space when the breadth is measured from the inside of the cargo battens (spar ceiling) and the measured depth is from the wood tank top ceiling to the underside of the deck beams. The length is measured from the inside of the fore and aft bulkhead stiffeners.


Broken stowage – is defined as that space between packages which remains unfilled. The percentage that has to be allowed varies with the type of cargo and with the shape of the ship’s hold. It is greatest when large cases are stowed in an end hold or at the turn of a bilge.


Cargo information – means appropriate information relevant to the cargo and its stowage and securing which should specify, in particular, the pre- cautions necessary for the safe carriage of that cargo by sea.


Cargo plan – a ship’s plan which shows the distribution of all cargo parcels stowed on board the vessel for the voyage. Each entry onto the plan would detail the quantity, the weight and the port of discharge. The plan is con- structed by the Ship’s Cargo Officer and would effectively show special loads such as heavy-lifts, hazardous cargoes, and valuable cargo, in add- ition to all other commodities being shipped.


Cargo runner – a general term used to describe the cargo lifting wire used on a derrick. It may be found rove as a ‘single whip’ or doubled up into a ‘gun tackle’ (two single blocks) or set into a multi-sheave lifting purchase. It is part of the derricks ‘running rigging’ passing over at least two sheaves set in the head block and the heel block, prior to being led to the barrel of the winch. Normal size is usually 24 mm and its construction is flexible steel wire rope (FSWR) of 6 X 24 wires per strand (wps).


Cargo securing manual – a manual that is pertinent to an individual ship, and which will show the lashing points and details of the securing of relevant cargoes carried by the vessel. It is a ship’s reference which specifies the on-board securing arrangements for cargo units, including vehicles and containers, and other entities. The securing examples are based on the trans- verse, longitudinal and vertical forces which may arise during adverse weather conditions at sea. The manual is drawn up to the standard contained in Maritime Safety Committee (MSC) Circular of the Organization, MSC/Circ.  745.


Cargo ship – defined as any ship which is not a ‘Passenger Ship’, troop ship, pleasure vessel or fishing boat.


Cargo spaces (e.g. cargo hold) – means all enclosed spaces which are appropriate for the transport of cargo to be discharged from the ship. Space available for cargo may be expressed by either the vessel’s deadweight or her cubic capacity in either bale or grain space terms.


Cargo unit – includes a cargo transport unit and means wheeled cargo, vehicles, containers, flat pallet, portable tank packaged unit or any other cargo and loading equipment or any part thereof, which belongs to the ship and which is not fixed to the ship.
