AIS tracking, SSAS, route optimisation and maritime intelligence in one workspace
BigOceanData gives fleet teams a shared workspace for vessel visibility, security alerts, voyage planning and operational investigation. Start with the capability you need, then add more as your operation grows.
Four connected capabilities. One operational picture.
From day-to-day fleet monitoring and security alerts to voyage planning and operational investigation, BigOceanData keeps the team working from one shared operational picture.
AIS Vessel Tracking
Monitor ship and fleet activity across sea routes and more than 4,500 ports and terminals using combined terrestrial and satellite AIS. Give the team one shared view for alerts, geofences, port and anchorage activity, history and voyage replay. When AIS alone falls short, Inmarsat-C and Iridium reporting keep your own vessels visible.
Core capabilities:
- Multi-source vessel visibility
- AIS blackspot resilience
- Alerts and area monitoring
- Port and anchorage visibility
- Voyage replay and investigation
- Fleet activity tracking
Route Optimisation
Compare route options against time, fuel, cost, ETA and operating constraints in one workflow, helping teams improve voyage efficiency, reduce costs and adapt as conditions change.
Core capabilities:
- Route comparison
- Weather-aware voyage planning
- Fuel, cost and emissions insight
- ETA and schedule management
- Live voyage monitoring
- Re-optimisation as conditions change

Ship Security Alert System (SSAS)
Receive, distribute and record Ship Security Alerts in the same platform your team uses for vessel tracking, so every alert arrives with position, track and surrounding context. BigOceanData helps teams respond faster, meet SOLAS and ISPS requirements, and keep a defensible record for every inspection.
Core capabilities:
- Live and test alert management
- Multi-channel alert distribution
- Position and track attached
- Always-on alert processing
- SOLAS and ISPS records
- Managed provider migration
Maritime Intelligence
Investigate vessel movements, port and area activity, incidents and historical patterns using live and historical maritime data in the same workspace as your fleet monitoring.
Core capabilities:
- Port and area activity monitoring
- Operational risk context
- Incident investigation
- Historical pattern analysis
- Performance benchmarking
- Reporting and intelligence views
Trusted by teams who rely on maritime visibility every day
“Maersk needed the ability to track containers. After signing a two-year contract with BigOceanData in for vessel tracking services, Maersk extended and expanded the agreement for a further 30 months, covering three times the original number of vessels and nearly double the number of tracked containers. Maersk continues to use the BigOceanData SSAS service, a cost-effective, well-supported solution.”

Head of GVPC at Maersk
“Our contract renewal with BigOceanData is a testament to the continued excellence of service and support the team provides. BigOceanData has been and will continue to be one of our key service providers at VertomCory, helping us to enhance the service package we provide to our key clients.”

“BigOceanData played a key role in de-risking the return of our vessel, SARBAS, from the Persian Gulf at the onset of hostilities. Their team provided excellent support over a weekend, rapidly setting up frequent Inmarsat-C position updates, seamlessly integrated with AIS data, to support a safer transit. The solution was highly cost-effective and delivered with efficiency and professionalism throughout. The team are a pleasure to work with.”

Ship Security Alert System (SSAS): a practical guide for operators
What an SSAS actually does, which ships must carry one, where the alert goes when it is pressed, and why most operators discover their weak point during a test rather than an incident. Most SSAS documentation describes a button. That is accurate and almost entirely useless, because the button is the part that works.

Vessel Geofencing: How to Build AIS Alerts Your Team Will Actually Act On
Defining maritime zones, writing alert rules that earn attention, and avoiding the alert fatigue that quietly kills most monitoring set-ups. Vessel geofencing lets a maritime team draw a boundary around a port, anchorage, terminal, coastal region, offshore asset or sensitive area, and be told when a vessel interacts with it. Instead of checking a mapContinue reading “Vessel Geofencing: How to Build AIS Alerts Your Team Will Actually Act On”

How to Evaluate a Vessel Tracking Platform
Most tracking platforms look identical in a demo. Here is what actually separates them, what “satellite AIS” means in practice, and the questions to take into a vendor call.

What Happens When a Vessel Disappears From AIS?
AIS is the foundation of vessel tracking, but it was never designed for uninterrupted global coverage. When a vessel stops reporting, AIS Continuity maintains visibility using independent position sources already available on many ships.

Which vessel tracking platform is right for your team? MarineTraffic, VesselFinder, or BigOceanData?
“Should we use you, MarineTraffic or VesselFinder? “ It is a question we are asked directly, and it deserves a straight answer rather than a sales pitch. The short version: if you are an individual who needs vessel positions, or a business looking for standalone AIS data feeds, VesselFinder is a sensible place to start. If you are a large organisationContinue reading “Which vessel tracking platform is right for your team? MarineTraffic, VesselFinder, or BigOceanData?”

From Live Positions to Better Decisions: The Real Value of Vessel Tracking
Vessel tracking is often reduced to a simple visual: a ship moving across a map. That is useful, but it is not where the real value sits. In practice, the value comes from what a team can decide once that movement is visible, interpretable, and connected to the operational picture around it. In shipping, timingContinue reading “From Live Positions to Better Decisions: The Real Value of Vessel Tracking”
