Voyage Data Recorder (VDR) and Simplified VDR (S-VDR) are systems that continuously record a ship's navigational data and play a critical role in accident analysis. These systems store information such as the vessel's position, speed, heading, radar data, and communication records—similar to a black box on an aircraft.

According to international regulations, VDR/S-VDR systems onboard commercial vessels must undergo an Annual Performance Test (APT) each year. These tests ensure that the system is functioning correctly and that its recording capabilities comply with relevant standards.

At STM Marine Electronics, our certified engineers carry out APTs for VDR/S-VDR systems with precision, provide the required documentation, and promptly address any identified issues. With our extensive stock of spare parts and 24/7 global service network, we ensure the safety and regulatory compliance of your VDR systems.
