12 FINAL RECORDING MEDIUM SETUP
12.1 FRM System Overview
The Final Recording Medium (FRM) is a solid-state storage unit capable of storing a minimum
of 12 hours of VDR-100G3/S data in compliance with IMO resolution A.861(20.). The difference
between a FRM and SFRM are: FRM can only be a fixed capsule; SFRM may be supplied as
float-free or fixed. The SFRM does not have to meet the penetration factor.
The primary function of the FRM/SFRM is to provide a protective capsule for the IMO required
data recorded by the VDR. This data will be used, in the event of an incident or accident by an
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.
The VDR-100G3 supports the use of single or dual capsules in a fixed or Float-free configuration.
Each FRM or SFRM has unique setup properties and the following sections should be consulted
prior to setting up the FRM.
Note! An FRM Configuration Sheet is available in Appendix 1 – FRM Maintenance
Sheet and should always
be completed during an FRM set-up. In the event of an
incident this information must be available in order to retrieve data from the FRM.
