Decorum Maritime is rethinking how ships stay safely on course. With its new DIDI Chart system, the company is bringing automation and cybersecurity together for one of navigation’s most critical tasks: updating electronic charts.
For decades, seafarers have relied on navigational charts to find their way across the world’s oceans. In today’s digital era, these charts come in electronic form, known as Electronic Navigational Charts or ENCs. Yet for many shipping companies, updating them remains a slow and manual process.
That is the challenge Decorum Maritime wants to solve. The Germany-based technology company has introduced DIDI Chart, a secure, automated solution that delivers ENC data directly to vessels, even when they have no internet connection.
“Reliable access to updated ENC data has become essential in modern navigation,” said Mairan Paul, founder of Decorum Maritime. “The widespread manual processes that crews have to carry out to supply the ECDIS with charts often remind me of the days of paper charts.”
Electronic Chart Display and Information Systems, or ECDIS, are mandatory on most large vessels under international regulations. Yet many ships still rely on crew members to manually transfer chart updates using USB drives or CDs. It’s a time-consuming task that can introduce errors or even open the door to cyber risks.
DIDI Chart was built with those risks in mind. The system uses Zero Trust architecture to verify every data transfer and ensures charts arrive integrity-checked and ready to install. It also works offline, making it suitable for vessels that spend long periods with limited or no connectivity.
According to Decorum Maritime, the solution combines automation with strong security controls, allowing shipowners to meet compliance requirements while keeping operations simple for crews. The company describes it as “secure by design,” emphasizing that its tools were developed for real-world maritime conditions rather than ideal network environments.
“DIDI Chart delivers the latest charts and permits securely, integrity-checked, and ready to install worldwide,” Paul said.
As regulators pay closer attention to cyber risk management in shipping, solutions like DIDI Chart show how digital tools can improve both safety and efficiency. For the crews who keep global trade moving, it’s one less thing to worry about on an already demanding voyage.
