Royal Dirkzwager

Specialist in the maritime and logistic industry

Thinking in solutions for the challenges in the maritime and logistics sector. That is what moved Royal Dirkzwager since 1872. By cleverly combining services such as monitoring, reporting, detection and  communication, we always know how to offer our customers the best solution. Whether it is about saving time and money, ensuring the safety of people and equipment at sea or reducing the burden on the environment.


We started as a ship reporting company back in 1872 and over the years we have expanded our service package. We operate in the heart of the shipping industry. Our fully equipped 24/7 control room monitors, reports and detects all incoming and outgoing vessel traffic in and around the port, waterways,  at sea and in the vicinity of offshore assets. 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, is a specialty and of great value to our customers. And that is the specialty Royal Dirkzwager offers.
