We started as a ship reporting company and over the years we have further expanded our service package. We offer real-time visibility of all vessels that affect your daily operations. Every day we provide more than 800 organizations in the maritime industry with up-to-date information. Each year we register no less than 200,000 ship movements. Well before arrival until gangway down, we inform the entire port community about the estimated time of arrival (ETA), the availability of nautical services and the exact berth details.


Why we do what we do

We work with the belief that the correct interpretation, combination and validation of maritime data can be of vital importance. Nowadays a lot of maritime data is freely available. Keeping an overview of all the data and interpret, combine and validate it the correct way, can be of great value to our customers and is a specialty.
