Difference between VDR and S-DVR
Simplified voyage data recorder that fulfils the same requirements of an VDR, but with less inputs. They can be carried by cargo ships of 3,000 gross tonnage and upwards instead of a VDR built after July 2002.
The voyage data recorder system, including all sensors, shall be subjected to an annual performance test. The test should be done by an approved testing or servicing Engineers / companies by manufacturers.
IMO Rules for VDR - MSC/Circ.1024 29 May 2002
Passenger ships and ships other than passenger ships of 3000 gross tonnage and upwards constructed on or after 1 July 2002 must carry voyage data recorders (VDRs) to assist in accident investigations, under regulations adopted in 2000, which entered into force on 1 July 2002.The mandatory regulations are contained in chapter V on Safety of Navigation of the International Convention for the Safety of Life at Sea, 1974 (SOLAS).
Like the black boxes carried on aircraft, VDRs enable accident investigators to review procedures and instructions in the moments before an incident and help to identify the cause of any accident.
