With the time slider at the top you can consult the occupation of the berths in the future.
You can “scroll” forward in time per 30 minutes (>) or per 6 hours (>|).
The green areas are berths where it is allowed to moor as inland barge.
The gray zones are berths where it is not allowed to moor as inland barge.
The red rectangles are seagoing vessels moored at a berth.
IMPORTANT:
To find out how long you can occupy a berth, “scroll” forward in time until you see a seagoing vessel appear. You must have left the berth before that moment.
