4 NW6860 Fixed HSS Capsule
4.1 General
The hardened storage server (HSS) forms the Fixed Final Recording Medium and is colored bright
orange for ease of location in the event of an incident. The HSS is designed to be mounted on the
´monkey island´ - 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 withstand the extreme shock, impact, pressure and heat exposure
requirements of the IEC Performance standards which mirror those enforced by the maritime and
aerospace authorities.
The HSS has the capacity to store audio, radar video and other data for a rolling 48-hour
(minimum) period as defined in the regulations. All power and data are passed to the HSS via one
single Ethernet cable. Connection is via a waterproof connector.
The HSS has a release mechanism to facilitate underwater recovery both by a diver or a ROV.
Suitable handles are provided to ensure that the capsule may be retrieved safely after release.
The HSS has an externally mounted underwater location beacon (ULB) with an activation sensor
to avoid inadvertent activation due to spray/rain/hosing off. The HSS (memory module) protective
capsule is painted a highly visible fluorescent orange with the required text: VOYAGE DATA
RECORDER, DO NOT OPEN and REPORT TO AUTHORITIES.
When the HSS has been damaged after an incident, e.g. the HSS was exposed to fire or the ship
has sunk, it may be returned to the manufacturer for the data to be extracted. Alternatively,
authorities may apply for instructions on how to extract the recorded data.
4.2 Indicators
When in unassembled state (and viewed form the bottom of the capsule part) a blue LED is
available to determine Link, Activity, and Error status during service.
4.3 Errors
If errors occur these will be indicated on the display of the Bridge Display Unit.
