Good decisions are based on clear insight

man looking at screen

Professionals in shipping, commodities, finance, insurance and law need more than great data. They need data and insight that cuts through the noise and tells them what they need to know.
Our customers need advanced analytics and artificial intelligence to bring to light patterns of behaviour that could raise concern or reveal commercial opportunities. They need risks calculated automatically with additional context that isn’t readily visible at a glance, reducing the need to spend hours or days of research to draw the right conclusions.
This is the kind of actionable insight we offer over 60,000 professionals around the globe every day.

What Our Customers Say

We are the maritime experts

As the trusted expert partner for almost 300 years, we bring you the complete view of maritime data for vessels and fleets, movements and behaviours, and incidents.

Our expertly managed maritime database, contains over one trillion data points that are constantly verified and contextualised with the use of AI. It is at the core of our suite of online tools and data feeds that help thousands of professionals save time collating and interpreting maritime data to get a clear view of risk, monitor maritime trade and seize opportunities.

Real-time and historical data on vessel characteristics, movements, ownership, sanctions, casualties, as well as ports and places come together in one place to form the complete picture of maritime trade around the globe.

data story diagram


Around 360m+ Automatic Identification System (AIS) messages are ingested daily. Most are captured via terrestrial receivers, but other important AIS data from deep sea tracks and busy lanes are captured by satellite partners. Even more data is captured via shipborne receivers and our exclusive access to Lloyd’s Agents around the globe.

Terrestrial network: AIS data is captured by land-based receivers in optimal locations along coastlines, in 4400 ports and places, covering all the major trading ports in the world. About a quarter of the 2200 receivers are owned and managed by us, bringing in exclusive AIS data to our database. The other receivers are operated by trusted partners. Our terrestrial network collects most of the AIS data for our database – around 300m AIS messages ingested dailyAll receivers are held to 95% uptime SLAs, so if they come offline, they are inspected and brought back online quickly.

Satellite network: Our partners Orbcomm and Spire provide complementary AIS data capture services using their satellite networks.

Since 2009 we have partnered with pioneer Orbcomm which uses their low-earth orbit (LEO) constellation of satellites and 16 ground relay stations around the world, benefitting from their exceptional ability to capture AIS from vessels in deep sea tracks.

In October 2019 we formed a partnership with Spire Global, which uses a nano-satellite constellation with particular visibility of vessel positions in high traffic zones such as the South China Sea and the Gulf of Mexico. In 2021 we integrated Spire Dynamic AIS, a shipborne AIS receiver service that consolidates AIS signals from nearby vessels and transmits them via satellite links, reducing the risk of data loss in high traffic zones such as the South China Sea.

Lloyd’s Agents: Our exclusive access to the network of over 500 Lloyd's Agents positioned in 170 countries gives us insight directly from ports across the globe. The Agents, mostly located in high-traffic ports, provide on-the-ground information to verify positions and port callings as well as create fresh and exclusive data when AIS signals aren't available or have been switched off. Over 24,000 port calls annually are provided by Lloyd’s Agents that aren't available through any other means. This brings even more data to our customers that can’t be obtained elsewhere.

Our expertly managed database transforms our data into actionable insight

data story diagram

Billions of data points flow into our expertly managed database for verification and contextualization with the use of AI to transform it into actionable analytics.


  • Advanced algorithms designed by experts to rapidly disseminate, match and verify data
  • Artificial intelligence creating advanced context around behaviour, its implications and risks


  • Industry expertise delivering analytics that are relevant and insightful
  • Analytical expertise devising methodologies that achieve optimal analytical results

Our data is transformed into data feeds, analytics, tools, reports, ratings and alerts that cut through the noise and help thousands of professionals get a clear view of risk, monitor maritime trade, and seize opportunities.


Our database is constantly updated and growing

We use only official and professional sources of vessel characteristics and ownership information. We have over 150 trusted sources including 60 commercial registries, 40 flag state registries, 20 class societies which include IACS members and P&I clubs, as well as other official bureaus that issue results of surveys, inspections, and other documentation.

Our analysts disseminate incoming vessel characteristics and ownership information, validate it against known data from independent sources, and verify any changes that should be made.


  • 52k+ vessel characteristics updated each month
  • 600+ vessel name changes each month
  • 600+ flag changes each month
  • 9k ownership details researched and updated each month
  • 22k vessel specifications are updated each month

Our terrestrial AIS receiver network grows by five new receivers each month, adding more AIS data and enhancing its overall accuracy, not just for vessel positions but to verify and update other pieces of information. AIS messages contain call sign, vessel name, and cargo type. If any of this data has recently changed for any vessel, we can capture it, verify it, and update our records.




Our processes for data collection, cleansing, enhancements, and output are all governed through COACT. This ensures that everything we do with the data meets and is measured against the same high standards on a continual basis.
