Ship and Barge Line-up

The Ship And Barge Line-up Explorer is used to view and calculate ship line-ups. The Ship and Barge Line-up Explorer is also used to view barge line-ups for barges that have routes based on a port location or that are assigned to a shipment. However, barge terminal berths cannot be managed with the Ship and Barge Line-up Explorer.

Line-up calculations are required for discharge berths. Line-up calculations enable the user to alter planned berths before shipment berthing takes place. Berthing priority is given to the shipment with the earliest actual time of arrival for the berth to which the shipment is assigned.

It is possible for more than one shipment to be waiting for discharge at a berth while other shipments are already unloading at these berths. Line-up calculations take berth unavailability into consideration, and extend line-up times accordingly.

Example: If a shipment was berthed, or about to be berthed, and the berth became unavailable for 4 hours, then the ship line-up calculations would be extended by 4 hours.

The berthing date, start-loading date, end-loading date, unberthing and departure dates can be calculated based on:

  • The time that a shipment that is already berthed will depart (ETD)
  • The time required between one shipment departing and another shipment being able to berth
  • The time between berthing and starting to load
  • The recorded loading rate and the total planned tonnage to be loaded onto the shipment
  • The time required between ending the loading and documentation completion
  • The time between unberthing and departure

Therefore, attaching and detaching shipment to a berth is part of the line-up calculations. These calculations are used to determine when and how the shipments are scheduled around a specified list of berths. This best optimises the berth usage so that shipments are not over-delivered.

The line-up calculations attempt to avoid shipment loading and unloading overlaps. By doing so, berth conflicts can be avoided or effectively managed.
