Weathernews introduces SeaNavigator Mobile, a new iOS and Android application designed to keep shore-based operations teams connected to their fleet at all times. SeaNavigator Mobile sits alongside SeaNavigator for Master, Weathernews' AI-powered co-pilot for onboard navigation, where SeaNavigator for Master gives masters the analysis and decision support they need at the bridge, SeaNavigator Mobile ensures the shore side can keep pace. Together, they close the communication loop between vessel and office.
From 24.5 Hours to 30 Minutes
The impact is immediate and measurable. In one observed case, a route change notification that previously required a follow-up phone call and an email reply, a process taking roughly 24.5 hours end-to-end was confirmed through the app in approximately 30 minutes. The updated voyage plan reached the vessel shortly after. This kind of reduction in lead time doesn't just improve efficiency. It changes what's operationally possible, compressing the window between a weather development and a vessel's response from nearly a full day to under half an hour.
Real-Time Fleet Monitoring
SeaNavigator Mobile gives operations teams a live map view of vessel positions and navigation data, providing an immediate overview of the fleet from any location. Vessels can be organized into custom groups, either private to an individual user or shared across a Weathernews Service Account with map displays and notifications filtered accordingly. Groups sync automatically with the SeaNavigator web platform, ensuring a consistent experience whether working from a phone or a desktop.
Vessels can be searched by name or IMO number and added to multiple groups simultaneously, with no limit on the number of groups that can be created. This flexibility allows teams to structure their monitoring around how they actually work, by region, vessel type, trade lane or any other operational logic.
AIS-Based Vessel Behavior Alerts
Running quietly in the background, the app's AIS-based alert system automatically flags abnormal vessel behavior without requiring constant manual oversight. The system analyzes speed data at hourly intervals and identifies two alert types: a Slowdown Alert, triggered when cumulative speed reduction exceeds a threshold calibrated to vessel type and a Drifting Alert, triggered when a vessel's speed falls below 0.5 knots for two or more consecutive hours.
Both alert types incorporate anomaly filtering to eliminate false positives from invalid AIS data and alerts are automatically suppressed in port and pilot areas where reduced speeds are expected. The result is a proactive layer of fleet awareness that surfaces situations genuinely warranting attention, not noise.
Mobile Voyage Plan Confirmation
When a plan requires a response, users will receive a notification, review the proposed route options and confirm or request revisions directly from the app. If no action is taken within a set period, the notification is automatically resent, ensuring time-sensitive confirmations don't get buried or missed.
Notification statuses clearly indicate which items are awaiting a response, which have been confirmed, and which are informational updates requiring no action. This removes the back-and-forth that has historically burdened both operations teams and routing coordinators, supporting faster response times and more consistent decision-making across the board.
Improving Operational Efficiency Across Shore-Side Teams
By consolidating vessel monitoring, AIS-based alerts and voyage plan confirmation into a single mobile platform, SeaNavigator Mobile enables shore-based operations teams to stay informed and respond to developments as they happen, regardless of the location.
Planned future features include automatic plan transmission upon approval, off-track alerts, and a request function allowing operators to submit changes to destination, speed and ETA directly from the app.
Drawing on more than 40 years of maritime weather expertise and a track record supporting over one million voyages, Weathernews will continue expanding SeaNavigator Mobile's capabilities to meet the evolving needs of shore-based operations teams.
SeaNavigator Mobile is now available on the App Store and Google Play, existing SeaNavigator users can access the app directly with their current account credentials.
