Read more →Maritime Info Hub: ECDIS Chart Updates & News
ECDIS chart updates keep bridge teams safe and compliant. On this page, we publish practical guides, product updates, and partner news that help you plan, install, and verify electronic navigational charts (ENC) across your fleet. If you’re migrating to S-100/S-101 or want to streamline weekly updates, start here. Stay current on ecdis standards updates, electronic navigational charts (ENCs), and the shift to S-100/S-101. This hub brings together our latest product releases, partner news, and plain-English guides that help bridge teams plan weekly updates, verify compliance, and work safer at sea.
Explore hands-on walkthroughs, checklists, and explanations of AVCS, ARCS, AIO and ADC—plus what S-100 means for real-world workflows. For operators rolling out Decorum’s DIDI Chart, you’ll also find zero-trust best practices and offline-install tips across fleets.
Why ECDIS chart updates matter
Accurate, up-to-date charts reduce risk and simplify audits. Most flag and class rules expect timely ENC updates; port-state control can request evidence that your ECDIS is current. That’s why many operators standardize the process—aligning master data, update windows, and proof of installation—so crews can focus on navigation instead of admin.
How we approache ecdis updates
Our DIDI Chart solution delivers official ENC updates quickly and securely. Updates are prepared centrally, transported with zero-trust controls, and installed on board via a verified offline medium. This design meets security requirements while fitting the reality of maritime connectivity. We support today’s S-57 data and the transition to S-100/S-101 formats.

FAQ: ECDIS & ENC updates
How often should we update ENCs?
Official producers release weekly chart updates. Many fleets align installs with a fixed day and keep proof of update on board.
What’s the difference between ENC and ARCS?
ENC are vector charts for ECDIS systems that meet SOLAS/IMO requirements; ARCS are raster charts. ENC enable layers, alarms, and better automation on ECDIS.
What changes with S-100/S-101?
The S-100 framework modernizes data models and services. S-101 will replace S-57 ENC, with new feature catalogues and portrayal—improving consistency and future add-ons.
How does Decorum handle ships with limited connectivity?
We deliver updates centrally and provide a secure offline install workflow. Crews can update ECDIS navigation systems even when the vessel is offline, with integrity checks and audit-ready logs.
