Notifications of this type inform you on current or (possible) upcoming port calls. You are able to set the focal point to be certain vessels you are interested in or certain ports or a combination of both (apart from the "ETA" notification which is vessel/fleet-based only).
Such notifications are the following ones:
Arrival: Get notified whenever,
- any vessel arrives at a selected port that interests you or
- a vessel of your choice arrives at any port or
- a certain vessel arrives at a certain port (combine vessel and port).
As you can understand, the information you will be getting depends on the asset you are based on. Tick the selection box next to the Notify only when stopped option to be receiving notifications only when the subject vessel is reported as stopped otherwise you will be getting notified the moment the vessel approaches the entrance of the port. In certain cases (larger ports with mapped berths/terminals), you may also click on the Docked option and get notified when the subject vessel docks at a berth.
Departure: Same logic with the above-described notification, only for departures! Again, you can define the notifications to be vessel-based, port-based or both.
Select the Undocked option to be notified the moment the subject vessel undocks from a berth/terminal.
ETA: This notification takes into account the ETA (Estimated Time of Arrival) as transmitted by the vessel's AIS system, as well as some other factors (expected route of the vessel, current speed), to calculate the ETA of any vessel to her destination port (as reported via AIS).
It is vessel or fleet-based. You can set this notification to inform you certain hours before the MarineTraffic-calculated ETA and keep notifying you every certain interval of minutes.
For example, you could set the notification to inform you 2 hours before the (calculated) ETA and keep informing you every 30 minutes. Based on the asset (specific vessel or fleet) of your choice, you will be getting the respective information when the subject vessel or any of the vessels that constitute the subject fleet approaches her destination port.
Note I: With the ETA notification, you may leave blank the second variable's field (Repeat every). This way, you will only be getting one notification with no repeats.
