For organisations that rely on real-time vessel intelligence, speed and precision matter equally.
Whether monitoring maritime security threats, tracking vessel activity around ports, supporting compliance operations, or analysing traffic through strategic chokepoints, customers increasingly need access to low-latency AIS data that is focused on the areas that matter most to them.
As part of our continued investment in AIS SeaOrbis, we have introduced a significant enhancement to our AIS TCP Stream service, enabling customers to receive real-time AIS data for specific geographic regions rather than consuming a full global feed.
The enhancement reflects a simple reality we hear from customers every day: while global AIS coverage remains essential for many use cases, not every organisation needs to process vessel movements from every corner of the world.
Delivering Greater Precision with Geofenced AIS Streaming
Customers can now define up to five geographic polygons and subscribe to a real-time AIS TCP stream filtered specifically to those regions.
Within each selected area, customers receive both positional and static AIS messages, providing a complete operational view of vessel activity while significantly reducing the volume of data being processed.
This capability enables organisations to focus exclusively on areas of operational relevance, such as:
- Territorial waters
- Ports and terminals
- Strategic maritime chokepoints
- Offshore infrastructure
- Exclusive economic zones (EEZs)
- Regional shipping corridors
For many customers, this delivers the low-latency benefits of TCP streaming without the complexity and infrastructure requirements associated with processing a global AIS feed.
Why Customers Asked for This
AIS consumers often face a difficult trade-off.
REST APIs provide targeted access to vessel data but require polling, making them less suitable for applications where near real-time visibility is critical.
TCP streams deliver continuous, low-latency updates, but historically this has often meant receiving a global feed regardless of the size of the area being monitored.
As maritime operations become increasingly specialised, customers have told us they want the speed and immediacy of TCP streamingcombined with the ability to focus on the locations that matter to theirbusiness.
This enhancement delivers exactly that.
Cleaner Data from the Start
Alongside geofenced streaming, we have also introduced an optional data cleansing layer within the AIS TCP Stream.
The service can automatically filter out clearly invalid AIS messages before they reach downstream systems, including:
- Positions located over land
- Impossible vessel speeds
- Invalid MMSI numbers
- Other clearly anomalous AIS transmissions
By removing low-quality data at the source, customers can reduce the effort required for downstream validation and improve confidence inthe data feeding operational systems, analytics platforms, and decision-supporttools.
The Benefits for Customers
These enhancements make AIS SeaOrbis TCP Streams more targeted, efficient, and operationally valuable.
Customers can benefit from:
More Relevant Data
Receive only the vessel activity occurring within designated areas of interest, reducing noise and improving focus.
Lower Infrastructure Costs
Reduce bandwidth consumption, storage requirements, and processing overhead by avoiding unnecessary global AIS traffic.
Improved Data Quality
Leverage optional cleansing capabilities to minimise invalid messages entering operational workflows.
Faster Decision Making
Support time-critical use cases with low-latency vessel intelligence focused on the regions that matter most.
Greater Operational Flexibility
Configure AIS delivery around business requirements rather than adapting systems to accommodate excessive data volumes.
Built Around Real-World Maritime Intelligence Requirements
At Lloyd's List Intelligence, product development is driven by how customers use maritime data in practice.
This enhancement is the result of ongoing collaboration between product, engineering, solutions consulting, and customers across maritime security, compliance, defence, and commercial shipping sectors.
By combining AIS SeaOrbis' multi-source AIS collection network with flexible delivery options, we continue to help organisations access the vessel intelligence they need in the most effective way possible.
Getting Started
Customers using this capability, as well as all new AIS TCP Stream customers, will connect through a new DNS endpoint.
Detailed connection guidance is available within our AIS TCP Stream documentation, and our Presales and Solutions Consulting teams are available to support implementation and onboarding requirements.
