This method creates projection groups based on the attributes of the containers in the current load list. XPS determines the Stow Factors for the containers in the load list and creates a group of projected containers that matches in type and number. If the containers in the load list have different Stow Factors, XPS creates a projection group for each Stow Factor. This way, the projected containers have the same Stow Factor as the actual containers. This is valuable because N4 requires that the Stow Factor of planned containers match the Stow Factor of projected containers.
Synchronizing projections reduces the projection counts of groups that have more projections than the load list requires. If projection groups are overplanned, the XPS client displays negative pool counts, allowing the ship planner to choose which uncovered projections to remove. You can use this method any time to update the projections to match the current load list.
If you need to retain a projection group for a booking that has no containers in the load list yet, be sure to plan those projections to the ship before using the synchronize command. If you have planned these unmatched projections, the XPS client presents a negative count for the pool. You can simply adjust the projection group’s totals up to recover them.
It is recommended to synchronize projections after all discharge containers are planned off the ship; otherwise, too many projections may be created. If you synchronize before discharge planning, you can correct the counts by simply synchronizing again.
When you synchronize projections to match the load list, XPS deletes any projections that are not yet preplanned and do not match containers on the load list. If you have created projections for containers that you expect to arrive but that are not yet on the load list, be sure to preplan those projections to the vessel before you synchronize projections. This will result in negative pool counts to highlight the issue, but the projections and preplans will remain.
To synchronize projections to match the load list:
Open a vessel.
From the Vessel menu, select Projections.
In the Projections window, from the Actions drop-down list, select Synchronize Projections to match Load List.
The projections in the Projections window update accordingly.
