The integrated platform combining vessel traffic services (VTS) with port operational management (PMIS), ensuring safety, efficiency and sustainability in coastal and port waters worldwide.
Where is the vessel? Is there a risk of collision or grounding? Is its berth ready, and are the pilot and tugs available? VTMIS brings together traffic monitoring, safety alerts and port information to help answer these questions.
What is VTMIS?
A Vessel Traffic Management and Information System links vessel traffic monitoring and safety support with port planning and information exchange. It combines vessel positions and movements, collision and grounding risk alerts, port call details and service readiness to support safe, coordinated arrivals and departures.
The exact scope varies by port. VTMIS can connect several systems, allowing VTS, port planners and other authorised users to work with the same up-to-date information.
VTS as the operational foundation
A Vessel Traffic Service is a service implemented by a government that can interact with vessel traffic and respond to developing situations within a defined area. Its purpose is to improve navigational safety and efficiency, protect life at sea and support environmental protection. This definition is paraphrased from IMO Resolution A.1158(32).
VTS provides relevant information, monitors and manages traffic, and responds to unsafe situations. The competent authority establishes the framework; the VTS provider operates the service; the ship’s master retains responsibility for safe navigation. SOLAS V/12 provides the international basis for VTS.
The VTS technical foundation
Before connecting VTS with wider port processes, its technical system already provides the tools for traffic monitoring and safety support. These remain the operational foundation of VTMIS.
Sensors
Radar detects vessels, AIS identifies them, cameras provide a visual check, and weather stations measure local conditions.
Core
The system combines these inputs into vessel tracks. It can match a radar target with its AIS identity and flag conflicting information.
Operator Workstation
A chart shows vessel positions, movements and alerts. Decision support tools help the operator spot conflicts and plan traffic.
Communications
VHF and digital services let the operator exchange information and instructions with vessels.
Why connect VTS with port operations
A VTS operator can see an approaching vessel but may need separate calls to check its berth, pilot or clearance status. Port planners may receive changed arrival times too late to adjust their bookings. Digitalization connects these separate sources, creating the link from VTS to VTMIS.
From VTS to VTMIS
VTMIS builds on VTS by linking safe vessel movements with port readiness. The aim is to identify traffic risks early, coordinate arrivals with available berths and services, and reduce avoidable waiting and repeated reporting.
For example, a delayed departure can affect the next arrival’s berth and create a traffic conflict in the approach channel. Sharing the revised times lets VTS, the berth planner, pilot station and tug operator adjust their plans together. Each organisation keeps responsibility for its own decisions.
