What is a HRU?
Hydrostatic Release Unit
Water Pressure activates a diaphragm at 1.5 - 4 m depth.
The diaphragm releases a spring loaded blade which allows life raft to float up.
The painter of the life raft, is still connected to a strong point on the vessel via a weak link. It pulls out completely and inflates the life raft.
Due to increased buoyancy, the weak link breaks and the life raft is now free from the vessel.
What is a weak link and why? (HRU)
A safety component designed to break under a specific load, allowing the LIFE RAFT or EPIRB to detach from the vessel when submerged.
EPIRB. What is it?
Emergency Position Indicating Radio Beacon
406 MHz - direct/space wave (UHF)
Cospas-Sarsat satellite system determines position < 3 miles.
Coded message identifies vessel.
> LUT > MCC > RCC > SAR
Also transmits 121.5MHz for SAR aircraft homing.
How long can an EPIRB last and how is it activated?
48hrs min once activated
-Hydrostatic release
-Salt water contacts
-Manual Activation instructions on EPIRB
How often should an EPRIB be checked?
MSN 1810:
Monthly - physically examined and self test function
Annually - performance test using suitable test equipment.
Every 5 yrs - S.B.M
What is a SART?
SEARCH AND RESCUE TRANSPONDER
-self contained waterproof radar transponder
-X band - 9 GHz - 3cm wavelength
How long can a SART last once activated?
96 hours in standby mode
