History of VDR/S-VDR, called Marine black box
■ Purpose of VDR: to investigate the ships accidents
■ History of VDR
・1989 introduction of VDR to International convention by Germany
・1991 VDR was installed on the commercial Ship in Europe.
・1994 Accident of RORO passenger ship "Estonia"
(sank in the Baltic sea and many people died.)
⇒ trigger to VDR installation requirement
・1995 a certain Classification Society prepared VDR Notation
■ Action of IMO (IMO: International Maritime Organization)
・1996 discussed at IMO/NAV42
・1997 Resolution A.861 (20) (performance standards) adopted
■ IEC (International Electrotechnical Commission)
・2000 Jul IEC61996 (Test standard) issued
■ SOLAS (The Safety of Life at Sea) amendments chapter V regulation 20
(Existing Passenger ships),
(Passenger ships and Cargo ships over 3000GT newly constructed after 1 Jul 2002)
・2000 Dec, Msc.99 (73) adopted
VDR installation was put into force on 1 Jul 2002
■ SOLAS (The Safety of Life at Sea) amendments chapter V regulation 20
(Existing cargo ships over 3000 GT constructed before 1 Jul 2002)
・2004 Dec, MSC.170 (79) adopted
S-VDR installation will be put into force on 1 Jul 2006
Carriage Requirements
SOLAS-V 20 amendments by MSC 170 (79)
Note) SOLAS-V 20 2.3 Exemption of S-VDR requirements
Administrations may exempt cargo ships from the application of above carriage requirements when such ships will be taken permanently out of service within two years after the implementation date specified.
Note
Implementation date is considered the first scheduled dry docking.
Ship bottom survey is required at least twice within 36 months during 5 years.
General Ideal of S-VDR
1. Regarding all sensors related to S-VDR, the same data of VDR is specified and AIS interface is added to the interfaces to VDR
2. All sensors related to S-VDR can be divided into three categories such as mandatory, dependable and conditional.
(a) Mandatory
GPS Date and time, ship's position, datum (world Geodetic System (WGS-84) co-ordinates)
Gyrocompass Heading
Log Ship's speed
Microphone(s) Audio on Bridge
VHF VHF Communication (XMT/RCV)
Radar Radar image (if impossible, AIS shall be connected.)
(b) Dependable
AIS Other ships' information
(If it is impossible to obtain radar image, AIS shall be connected.)
(c) Conditional
Other items all items required in A.861(20) related to VDR, except equipments mentioned in paragraph "(a) Mandatory"
(If signals are obtained in the formatter specified by IEC61162, it shall be connected with S-VDR.)
