12.2 Fixed Capsules
Fixed capsules are designed to be mounted externally on the bridge top of the ship and are
designed to ensure that critical VDR data can survive the following environmental conditions:
Impact shock: 50 half sine-wave pulse for 11 milliseconds;
Fire Exposure: 1,100 degrees centigrade for one hour and 26 degrees centigrade for 10
hours;
Deep Sea Pressure: 30 days under water at MPa (equivalent to 6,000 m depth).
Fixed capsules can be supplied with either a VDR as an FRM or as an. In the case of fixed FRMs
for VDRs, the fixed capsule must additionally meet the penetration standard of SVDR which is
250 kg mass dropped 3 metres impacting with 100 mm diameter pin;
12.2.1 Rutter FRM (RUT-02447) Fixed Capsule
Figure 12–2- Rutter FRM (RUT-02447) Fixed Capsule
The Rutter FRM (RUT-02447) Fixed Capsule is an armoured stainless steel (A316) capsule,
connected to other system components via two cables (Ethernet and Power cables).
The Rutter FRM (RUT-02447) Fixed Capsule is the “Black Box” storage medium for ships. It is
coloured bright orange for ease of location in the event of an incident.
The Rutter FRM (RUT-02447) Fixed Capsule is approved to be used with both VDRs and SVDRs
The Rutter FRM (RUT-02447) Fixed Capsule is designed to be mounted externally close to the
bridge—typically on the bridge top—and is fitted with an acoustic beacon to aid underwater
recovery by a Remotely Operated Vehicle (ROV) or diver in the event of an incident.
The unit is designed to meet the requirements of the IEC Performance standard which are the
same as those enforced by the maritime and aerospace authorities.
The protected memory is stored in the retrievable capsule and is connected by a quick-release
cable-connector assembly to the deckmount which contains the server-central processing unit.
