Q

what are the advantages of the standardised shipping container over the conventional break bulk carrier?

A
  • faster + cheaper turn round time for ships
  • secure + speedy factory-to-customer delivery
  • much reduced damage to cargo
  • much reduced in loss due to pilferage
  • an ideal medium for multi-modal transport. It is as well suited to rail or road as to sea transport

Q

what are general-purpose containers generally made out of?

A
  • steel

- timber or plywood floor (alleviate some of the problems of sweat)

17
Q

what is the key to the strength of containers?

A

floor members + four corner posts

18
Q

where are all the securing + lifting points of a container directly connected to?

A

corner posts

19
Q

where is a container designed to be weather tight from?

A

only above

20
Q

what is the gross weight of 20’ containers (generally)?

A

22,860 kg (24 tons)

21
Q

what are the differences between 20’ containers and Bulk Containers?

A
  • they have three circular hatches in the roof for loading of bulk material
  • a hatch at the bottom of one of the doors for discharge
  • steel floors for ease of cleaning and facilities for securing polythene liners if required
22
Q

what are the differences between 20’ containers and Ventilated containers?

A
  • fitted with a passive ventilation system adjacent to the top and bottom side rails
  • vents are designed such that they resist the ingress of water
23
Q

what are the differences between 20’ containers and Open-sided Containers?

A
  • one open side fitted with a gate (in four sections) + a roll down curtain that may be secured to the top rail
  • major use for transporting livestock + some perishable commodities
  • the fitting of side gates means that the side wall strength will be below the 0.6 standard
24
Q

what are the differences between 20’ Containers and Open-top Containers?

A
  • used for large, heavy, tall or awkward items that cannot be loaded through the doors of a GP container
  • enable heavy items to be lifted without lifting them over the sides the door header is removable so they can be loaded from that end
  • roof battens may be refitted + top covered with tarpaulins
25
Q

what are the differences between 20’ containers and Half-height Containers?

A
  • only 4’03” tall
  • avoids wasted space when loading high density cargoes e.g. steel rods + pipe
  • have same max gross weight limits
  • open-top containers with removable door headers + roof battens
  • tops may be covered with tarpaulins
26
Q

what are the differences between 20’ containers and Flat Rack Containers?

A
  • same but with no sides or tops
  • can be used for unusually large/awkward loads
  • loading cargo that fits within cell guides but not within internal dimensions of an open-top container
  • no facilities for tarpaulin tops so cargo itself must be protected if necessary
  • exceptionally large cargo can be loaded across several flat rack containers placed side-by-side in the stow
27
Q

what are the differences between 20’ containers and Insulated Containers?

A
  • used when blown-air refrigeration is provided by the ship
  • insulated against heat loss
  • have T-section flooring + battens on doors to allow free circulation of refrigerated air
  • should have a 75 mm space over the cargo for the same reason
28
Q

what are the differences between 20’ containers and Refrigerated Containers?

A
  • insulated in a similar manner to insulated containers
  • have either integral or clip-on refrigerated units that are powered from the ship’s supply
  • maybe clad in steel, aluminium alloy or GRP
  • some may be internally lined with stainless steel
29
Q

what are the differences between 20’ containers and Tank Containers?

A
  • simply stainless steel tanks fitted within a standard 20’ or 40’ framework
  • filling port at the top centre
  • a discharge port at the bottom of one end
  • used for carriage of a variety of both hazardous and non-hazardous liquids
30
Q

how many figures are in a container space code?

A

6

31
Q

how does the 6 figure code describe the position of each container?

A
  • in three dimensions
  • fore and aft
  • athwartship and vertically
32
Q

what are the first 2 figures specifying in the planning and stowage code?

A
  • the bay (or row) number
  • commencing at the bow
  • odd numbers refer to 20’ containers
  • even numbers refer to 40’ containers
33
Q

what are the second pair of figures specifying in the planning and stowage code?

A
  • athwartship location
  • commencing from the centreline
  • odd numbers represent starboard cells
  • even numbers represent port cells
34
Q

what are the third pair of figures specifying in the planning and stowage code?

A
  • vertical location
  • even numbers represent full height containers (starting with 02 at the bottom of the hold)
  • odd numbers represent half-height containers
