VDR / SVDR & Annual Performance Test
VDR and SVDR are the vessel's black box: they record voyage data and are essential in incident investigations. RNA covers installation, annual testing and full repairs.
Role of VDR and SVDR
The Voyage Data Recorder and Simplified VDR log route parameters, bridge audio, radar video and navigation signals. Beyond a regulatory requirement, they are essential in incident investigations and continuous operational safety improvement.

Frequently asked questions
Is VDR APT required every year?
Yes. The Annual Performance Test is a yearly requirement per IMO resolutions and is verified by classification societies and PSC.
Do you issue the APT certificate?
Yes, we deliver the technical report and certificate signed by an authorized engineer, ready for audit.
My VDR is end-of-life — can we keep it?
We perform retrofits and replace with current models when the OEM discontinues parts. We assess the best cost-benefit case by case.
