Netwave’s Simplified VDR technology is scalable to support both system requirements based on the same foundation components but designed with ease of installation and particularly retrofit installation requirements in mind.
Features
Netwave (S) VDR Captured Data
- Date and time
- Ship’s position in latitude and longitude
- Speed: Through the Water
- Heading as indicated by the ship’s compass.
- Bridge audio picked up by microphones positioned on the bridge
- VHF communications relating to ship operations
- Radar data from one of the ship’s radar installations
- AIS data, if it is impossible to obtain radar data then AIS target data should be recorded as a source of information regarding other ships.
- Additional data not applicable to SVDR (under resolution A.861(20),
- Echo sounder, main alarms, rudder order and response, engine order and response, hull openings status, watertight and fire door status, accelerations and
hull stresses, wind speed and direction

Technology Overview
What is a Simplified VDR or (s)VDR?
In 2004 amendments to Regulation 20 of SOLAS Chapter V introduced a requirement for a simplified version of a VDR – to assist in casualty investigations, cargo ships, when engaged on international voyages. S-VDRs are equally relevant in terms of data capture of operational activity on board the vessel, but an S-VDR is required to collect less information.
Essentially, both systems collect and protect data of incidents or events on board for a minimum of 12 hours of uninterrupted recording. Both devices require bridge microphones, radar video and VHF audio to capture navigational data but the full VDR has additional compulsory channels to be recorded, for example echo sounder, propulsion, water tight doors, fire detection.
