Chimney App

April 2015
Press release

The goal of the chimney Intelligent plug-in is to increase safety in the yard. On terminals chimney stacks are undesired because of safety due to the risk of falling when handling other containers, and the risk of falling due to wind.

Here, we define a pilein the yard as a chimney (stack) when either:

1. The difference between the pile height of the pile and the maximum pile height of the adjacent piles (in the same bay) is

  • 2 or more
  • 3 or more (depending on user configuration)

2. In RTG terminals, the pile on the lane closest to the truck lane is already a chimney when it is higher than its adjacent inward pile

Due to stacking parameters, and loading sequences, chimney stacks will evolve.

  • On RTG terminals, for safety reasons, chimneys in the yard need to be avoided
  • On ASC terminals, in case of approaching storm, chimneys in the yard need to be avoided and now manual planning is needed to prepare the yard

 The app will

  • Identify the chimney stacks
  • Avoid new chimney stacks
  • List the moves to resolve chimney stacks
  • Make the chimneys visible in the TOS

Chimney app location

  • Plan moves for the containers to new piles
  • First take chimneys of MTYs  down
  • Then take chimneys of fulls down
