VDR & SVDR
The Voyage Data Recorder and Simplified Voyage Data Recorder are essential safety systems installed on ships to record critical navigation and operational data from the vessel’s bridge. Similar to an aircraft “black box,” these systems continuously record important information such as navigation data, radar images, bridge audio communication, alarms, and sensor inputs. The recorded data is used for incident investigation, safety monitoring, and accident analysis. VDR and S-VDR systems collect data from various onboard equipment including Radar, Gyro Compass, ECDIS, Automatic Identification System, and Speed Log. Installation of these systems is required for many vessels under regulations set by the International Maritime Organization according to the SOLAS Convention.

Common VDR & S-VDR Issues
Ships may experience several VDR system problems that require professional technical support, including:
Sensor data not recorded
Radar image recording failure
Audio recording malfunction
Interface communication errors
Storage capsule faults
System alarms or software errors
Our experienced marine technicians can quickly diagnose and repair these issues onboard, ensuring reliable system operation.
VDR / S-VDR Annual Performance Test (APT)
The Annual Performance Test (APT) ensures that the Voyage Data Recorder and Simplified Voyage Data Recorder are functioning correctly and recording all mandatory bridge data.
During the test, our certified engineers verify:
Navigation sensor data recording
Radar image capture
Bridge audio recording system
Alarm and event logging
Data storage capsule performance
Power supply and backup systems
The APT confirms the system is fully operational and compliant with international maritime regulations.
What is a VDR?
A Voyage Data Recorder (VDR) is an onboard system that captures and stores a vessel’s navigational, operational, and communication data. This information is critical for investigating maritime incidents and conducting safety analyses to improve ship operations.
What is an SVDR?
A Simplified Voyage Data Recorder (SVDR) is a streamlined version of the VDR, tailored for smaller vessels. It records essential navigational and operational data, offering vital voyage information at a more cost-effective solution for maritime operations.
Why is VDR important for maritime safety?
The VDR is essential in maritime operations as it records critical voyage data, enabling the investigation of maritime incidents, identifying their causes, and supporting the enhancement of safety procedures and regulations to prevent future accidents at sea.
How long is the data stored in a VDR?
VDRs are mandated to retain a minimum of the last 12 hours of voyage data. However, many modern systems are capable of storing significantly longer periods of data, depending on their storage capacity and configuration, providing a more comprehensive record of a vessel’s operations.
Can the data from a VDR be accessed remotely?
Certain advanced VDR systems offer remote access to voyage data, enabling real-time monitoring and analysis. This capability is valuable for fleet management, enhancing operational efficiency, and supporting proactive decision-making at sea.
How is the data from VDR used in accident investigations?
VDR data is vital for reconstructing the sequence of events leading up to a maritime incident, assessing the crew’s actions and decisions, and identifying any equipment malfunctions or operational shortcomings.
How does a VDR work?
A VDR gathers information from multiple shipboard sensors and systems, including GPS, radar, engine parameters, and bridge audio communications, and securely stores it in a crash-protected unit for subsequent retrieval and analysis.
What kind of data does a VDR record?
A VDR captures comprehensive voyage data, including navigational details such as position, speed, and heading, bridge audio communications, radar imagery, engine and hull performance metrics, as well as alarm signals.
Are VDRs mandatory on all ships?
VDRs are compulsory on most large commercial vessels, including passenger liners and cargo ships above specified tonnage, in accordance with international maritime safety regulations.
What is the difference between VDR and SVDR?
The primary distinction is that VDRs offer comprehensive data recording across a wide range of shipboard systems, whereas SVDRs are streamlined for cost-effectiveness, providing essential voyage data recording tailored to smaller vessels.
Conclusion
VDR and SVDR systems are vital for strengthening maritime safety by recording and storing detailed voyage data. These systems are crucial for investigating incidents, conducting safety analyses, and refining navigational procedures. By ensuring compliance with international maritime regulations and offering valuable operational insights, VDR and SVDR systems help prevent future accidents and enhance overall safety at sea.
