Our company is certified and approved to perform inspections of the black boxes with certificates APT  and COC  for the following types of VDR:

  • Fruno VR-3000-VR-5000-VR-7000

  • Danalec DM-100,DM-200,DM-300,DM-400 and DM-500

  • NETWAVE NW-4000 AND NW-6000

  • KelvinHughes Manta Digital

  • CONSILIUM M2,M3,M3,5,M4 AND F1


  • RUTTER VDR-100G2 AND 100G3

When performing an annual audit of the black boxes is made:

  • VDR configuration check

  • check the software version

  • external inspection, check the connections and damage

  • download 12-hour recording with subsequent analysis of the VDR

  • check the expiration date of batteries (redundant power base unit, batteries sonar beacon and float free capsules)

  • check all sensors (data acquisition and correctness)

  • verification of VDR 2 hour on the backup power source

  • APT and the certificate issued not later than 30 days after issuance of a certificate COC

Voyage data recorder (VDR) - a system of recording and storing data on a sailing received from external sources:

  1. Date, time, position sensors from GPS.

  2. Speed ​​(relative to water or soil)

  3. Vessel course - gyrocompass

  4. Image with radar or data from  AIS *

  5. Sound from microphones (in the wheelhouse at the nodal locations on the bridge wings and from VHF p / st)

  6. Depth sonar *

  7. Alarm system with monitoring vessel *

  8. Access control with door sensors, etc. *

  9. Water sensor, fire alarm *

  10. Position of the rudder *

  11. Screws *

  12. Thrust level *

  13. Wind speed and direction anemometer *

* - Sensors are connected to the VDR, if available.

Incoming data is digitized and stored in a capsule, which is of two kinds:

  • Free bubble (search is done on a EPIRB)

  • Mounted on the roof of the vessel (search sonar beacons)

The capsule data is stored for at least the last 12 hours. 

Under the rules of all cargo vessels in service shall be equipped with a data logger voyage, allowing simplified configuration, in the following order:

  • cargo ships of 20,000 gross tonnage and upwards constructed before 1 July 2002 - during the first scheduled dry-docking after 1 July 2006 but not later than July 1, 2009

  • cargo ships of 3,000 gross tonnage and upwards but less than 20,000, constructed before 1 July 2002 - during the first scheduled dry-docking after 1 July 2007 but not later than July 1, 2010
