Complete Visibility Across Global Waters
BigOceanData delivers real-time vessel monitoring powered by high-quality terrestrial and satellite AIS data, providing reliable coverage where it matters most. Designed for operational teams, analysts and maritime decision-makers, the platform gives users precise visibility at fleet and vessel level.
From real-time alerts, SSAS integration and area monitoring to port and anchorage visibility, voyage replay and fleet activity tracking, Vessel Tracking transforms maritime data into actionable intelligence.
From live monitoring to operational response
BigOceanData helps teams move from vessel awareness into investigation, coordination and action in one connected workflow. Use alerts, zones and SSAS to surface events that need attention, then bring voyage replay, port activity, fleet context and vessel history together to understand what happened and decide what to do next.
The result is faster response, clearer investigations and stronger operational control, without the delays and friction of switching between disconnected systems.

“Maersk needed the ability to track containers. After signing a two-year contract with BigOceanData in September 2016 for vessel tracking services, Maersk extended and expanded the agreement in early 2018 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.”

“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.”

BigOceanData combines multiple AIS data sources, including terrestrial AIS, satellite AIS and additional maritime data inputs, improving coverage and reliability compared to single-source solutions. Update frequency depends on AIS source and location, but BigOceanData combines multiple feeds to improve update rates and consistency.
Accuracy depends on AIS signal availability, but by combining multiple data sources, BigOceanData improves position frequency and reliability, particularly in challenging areas such as open ocean or high-traffic regions.
Yes. The platform provides global coverage, including coastal and open ocean regions, supported by satellite AIS and terrestrial networks.
BigOceanData enhances visibility by combining multiple data sources and applying intelligence to vessel movements. While AIS gaps can occur, the platform helps provide a more complete operational picture than single-source solutions.
Yes. Users can track their own fleet as well as third-party vessels, supporting operational monitoring, chartering, market intelligence and risk awareness.
Yes. Users can set up alerts for vessel movements, port arrivals and departures, and defined geographic areas to stay informed and respond quickly.
Yes. BigOceanData provides access to historical vessel data, allowing users to analyse past voyages, trading patterns and operational behaviour.
Vessel tracking is one of the three core pillars of the BigOceanData platform, alongside Route Optimisation and Maritime Intelligence, enabling connected operational decisions.
BigOceanData combines multi-source AIS data, operational workflow tools, route optimisation and maritime intelligence to provide a more connected decision-making platform.
