Liferaft
A
liferaft is your last means of defense to save crews lives,
make sure they get serviced annually
Never roll a liferaft, you could upset some of the liferaft's
workings such as the painter line, the liferaft has breather
holes at the bottom of the raft incase any water enters
the raft and also to stop the rubber eroding.
If
a vessel sinks and you did not have time to launch the liferaft
manually, the hydrostatic release will operate when it is
submerged under the water between 1.5 - 4.0 metres
The
pressure of the water pushes down on a vertical spring releasing
a second spring which is under a lot of torque this pushes
a very sharp blade out cutting the attachment line releasing
the SENHOUSE SLIP

The
liferaft now floats free to the surface pulling the painter
line out, once all the painter line is pulled out it will
pull a wire that is attached to a THANNER OPERATING HEAD,
this then pierces the foil on the compressed Co2/nitrogen
filled canister.
The
Canister is connected to 2 hoses which are connected to
the liferaft's sponsons
Once the liferaft is inflated the buoyancy of the liferaft
breaks the weak link on the hydrostatic release leaving
the liferaft on the surface RFD LIFERAFT INFLATED LENGTH
OF PAINTERLINE
The
length of painter line inside your liferaft is stamped on
a label on the liferaft If you launch a liferaft manually,
leave the painter attached to the hydrostatic release
