What does the position of the container on board represent?
In order to accurately represent the loading position of each container on board the ship, so as to facilitate computer management and the correct identification of relevant personnel, each loading position on the container ship should be represented by an internationally unified code numbering method.
At present, the code numbering of container position of container ships is based on the method prescribed by ISO/TC104 Committee. It is based on the longitudinal arrangement of containers on board the ship. The coordinates of each container position are expressed in six digits (010102; 020202; 010282). The first two of them represent the line number, the middle two represent the column number, and the last two represent the layer number. Line number, column number and layer number of each group of code less than 10 zero in the previous position.
Line number (BayNo.):
The ordinal number of containers in the longitudinal (bow-stern) direction of the ship. As the longitudinal coordinates of container location. From the bow to the stern of the vessel, the containers with 20ft boxes are 01, 03, 05 and 07 in turn. Odd number representation.
When two consecutive 20ft containers are used to load 40ft containers, the line number of the 40ft containers is expressed as an even number between the odd lines of the two 20ft containers occupied.
II. Column number (Row No. or Slot No.):
The sequence number of containers in the transverse (left and right) direction of the ship. As the transverse coordinate of container location. Based on the mid-longitudinal section of the ship, 01, 03, 05 and 07 are taken from midship to starboard. The odd number means 02, 04, 06, 08 to port side. Even number representation.
If there is a column in the mid-longitudinal section of a ship (when the total number of columns is singular), the column number is 00.
Tier No.
The sequence number of containers in the vertical (upper and lower) direction of the ship. As the vertical coordinate of container location.
In the cabin, the lowest level in the whole cabin is used as the starting layer, and from bottom to top, 02, 04, 06, 08.. Even number representation.
The lowest deck of the whole ship is used as the starting deck, and 82, 84, 86 and 88 are used from bottom to top. Even number representation.
Obviously, each loading position of the whole ship corresponds to the unique six-digit box coordinates, whereas a certain range of box coordinates must correspond to a specific and unique loading position on the ship.
