1.1.7 Final Recording Medium (FRM/SFRM)
The Final Recording Medium (FRM/SFRM) is a solid-state storage unit capable of storing a minimum of
12 hours of VDR-100G2 data in compliance with IMO resolution A.861(20.). The difference between a
VDR and a Simplified-VDR mainly relates to the number of recording channels and their characteristics.
Both systems require radar video, bridge microphones and VHF audio, in conjunction with position data,
heading and course information, to be recorded for a minimum of 12 consecutive hours.
• The primary function of the FRM/SFRM is to provide a protective capsule for the IMO required
data acquired by the VDR. This data will be used, in the event of an incident, by an accident
investigation team.
The FRM/SFRM is mounted on the exterior deck of the ship and connected to the DMM.
The FRM/SFRM receives data from the VDR via an Ethernet link.
The SFRM is available in two types: float-free and fixed.
