VDR – SVDR Annual Performance Test APT

The Annual Performance Test (APT) is a mandatory test required by the International Maritime Organization (IMO) to ensure the proper functioning of Voyage Data Recorder (VDR) and Simplified Voyage Data Recorder (SVDR) systems. The APT aims to verify the accuracy, completeness, and retrievability of recorded data, including audio recordings from the bridge, images from the radar, and other relevant data. The test assesses the system’s compliance with the IMO’s performance standards and identifies any deficiencies or malfunctions that need to be addressed.

VDRs and SVDRs are critical safety devices that record valuable information for accident investigation and safety improvement. The APT is necessary to ensure that the VDR/SVDR system is working correctly and providing accurate and complete data. Without a functioning VDR/SVDR, accident investigations would be incomplete, and safety improvements would be compromised. The APT also helps to identify any deficiencies in the VDR/SVDR system, allowing vessel owners and operators to take corrective action and maintain the highest safety standards.

The APT should be conducted by an approved service provider with the necessary expertise and equipment. The service provider should be accredited by the VDR manufacturer or an authorized service agent and have access to the latest software and test equipment. Vessel owners and operators are responsible for selecting an approved service provider and ensuring that the APT is conducted within the required timeframe.

The APT consists of two parts: the static test and the dynamic test. The static test is performed with the vessel at the pier or dock, and the dynamic test is performed while the vessel is underway. During the static test, the service provider checks the system’s power supply, data storage capacity, and other critical components. The dynamic test involves verifying the proper functioning of the VDR/SVDR system’s sensors, recorders, and data transfer interfaces. The service provider checks for any deficiencies or malfunctions and provides a detailed report on the system’s performance.

• Verification of the proper installation and operation of the system’s hardware components
• Verification of the proper operation of the system’s software components, including the recording, playback, and data retrieval functions
• Verification of the proper operation of the system’s power supply and backup power systems
• Verification of the proper operation of the system’s interface with other onboard equipment, such as the GPS and radar systems
• Verification of the proper operation of the system’s external communications interface, including the playback of data to external devices

To ensure your VDR and SVDR systems pass the APT with flying colors, it’s important to take a proactive approach to maintenance and testing. Here are some tips to keep in mind:

• Conduct regular maintenance: Regular maintenance is essential to ensure the proper operation of your VDR and SVDR systems. This includes cleaning the equipment, checking for any signs of wear or damage, and replacing any faulty components.
• Test the systems regularly: In addition to regular maintenance, it’s also important to test the VDR and SVDR systems on a regular basis. This can help to identify any issues before they become serious problems.
• Follow the manufacturer’s guidelines: It’s important to follow the manufacturer’s guidelines for the installation, operation, and maintenance of your VDR and SVDR systems. This can help to ensure that the systems meet the highest standards of safety and reliability.
• Keep accurate records: It’s important to keep accurate records of all maintenance and testing activities for your VDR and SVDR systems. This can help to demonstrate compliance with regulatory requirements and can also
