This section describes how to use and configure the Predefined Working Pattern (PWP) feature, which is available if you license the Quay Commander Option. With the PWP feature, you can define the general load and discharge work patterns for vessels calling at your port.
Using PWP can reduce the planning time significantly, especially for sites that have the same or similar sister ships regularly call at their terminal. With PWP, the planner can use automated planning features such as AutoFlow to load containers in the predefined work sequence.
A Predefined Working Pattern is a stored sequence of slots within a vessel bay that dictates the normal order in which containers are loaded or discharged. By default, XPS assigns a load and discharge PWP, but you can define the working pattern for each bay. Usually, you define working patterns for each vessel class, rather than for an individual vessel. You can also override the general patterns in specific instances.
With the PWP option, you can:
Choose from a list of available work patterns for either 20s or 40s.
Reuse work patterns for each vessel class.
Override the general work patterns in specific instances.
List work patterns for each selected bay.
Use automated planning features to load containers in the pre-defined work sequence.
Include hatch lid configurations in your container sequencing.
When configured correctly, XPS automatically:
Predetermines the discharge sequence
Predetermines the load sequence
Generates sequence numbers for projections when planned to the ship
Assigns projections to the proper work queues, considering special cases like twin-lift and paired-20 sequences
