VDES and the Future of Maritime Communications: Preparing for IMO’s New Regulatory Standard

The International Maritime Organization (IMO) is moving forward with a transformative update to the SOLAS regulatory framework: the introduction of the VHF Data Exchange System (VDES). Seen as the next evolution of AIS, VDES strengthens maritime communications at a time when risks like AIS spoofing are on the rise.

By 2028, VDES will likely become a mandatory carriage requirement, shaping the way vessels handle ship-to-ship and ship-to-shore exchanges. For shipowners, managers, and compliance teams, this represents both a challenge and an opportunity.

What is VDES?

VDES maritime communications are built on the foundation of the Automatic Identification System (AIS), but with enhanced capabilities. Where AIS has traditionally supported collision avoidance and vessel identification, VDES adds:

• Data-rich exchanges between ships and shore
• Secure, authenticated communication channels
• Resilient connectivity to address spoofing and interference risks

Think of VDES as AIS 2.0, not a replacement, but an upgrade designed for modern maritime operations.

Why is IMO Introducing VDES?

The IMO’s decision to integrate VDES into SOLAS Chapter V and related performance standards reflects a growing need for safer, more reliable communication systems. Three key drivers stand out:

Combatting AIS spoofing

Malicious actors increasingly manipulate AIS signals, creating false positions or hiding vessel activity. VDES introduces mechanisms for authentication and more secure communication, significantly reducing spoofing risks.

A non-IP-based backup

As digital navigation expands, VDES ensures ships retain a secure communication channel independent of the wider internet.

Integration with S-100 ECDIS systems

With the rollout of S-100 ECDIS starting in 2026, VDES supports a seamless, resilient ecosystem for navigation and data sharing.

Together, these factors make VDES more than a technology upgrade; it’s a foundation for future-proof, secure ship-to-shore communications.

Compliance Timeline and What It Means for Shipowners

The IMO is expected to adopt the finalized standards in 2026, with entry into force on January 1, 2028. For shipowners and operators, this means:

• Mandatory carriage requirements: VDES units will need to be carried alongside or integrated with AIS.
• Upgraded cybersecurity: Ships will benefit from authenticated transmissions that strengthen digital safety.
• Operational readiness: Procedures will need updating to reflect the new SOLAS VDES requirements.

This isn’t just another equipment mandate. It’s a fundamental shift toward a maritime digital communications standard designed for resilience.

How NAVIREGO Supports Compliance Teams

While NAVIREGO does not provide VDES hardware, our platform plays a vital role in ensuring organizations are ready for regulatory shifts like this. NAVIREGO enables:

• Real-time regulatory updates: Stay on top of evolving VHF Data Exchange System IMO guidance and performance standards.
• Accessible compliance information: Technical and QHSE teams can quickly find adoption timelines and operational expectations.
• Workflow integration: Easily embed new SOLAS VDES requirements into safety management systems (SMS) across the fleet.
• Audit preparation: Ensure documentation and procedures reflect the latest standards for both internal and external inspections.

In short, NAVIREGO acts as a maritime compliance platform that helps turn regulatory updates into actionable steps.

Closing Thoughts: A Secure Future for Maritime Communications

AIS has served the industry for decades, but the challenges of spoofing and interference demand stronger safeguards. VDES maritime communications represent the next chapter, combining security, resilience, and data-rich functionality to meet the demands of modern shipping.

For maritime professionals, the key is preparation. With VDES set to enter into force in 2028, shipowners and compliance teams should already be aligning their documentation, systems, and expectations.

NAVIREGO ensures you’re not just aware of these changes, but fully prepared to act on them. By delivering regulatory clarity and supporting regulatory updates in maritime communications, we help technical and compliance teams manage transitions with confidence.
