SOLAS / CCS Marine Stainless Steel Hydrostatic Release Unit - HRU For Liferaft

SOLAS / CCS Marine Stainless Steel Hydrostatic Release Unit - HRU For Liferaft

1. Application
The hydrostatic release unit is inflating life raft rapid release equipment. When the boat sink in accident, they can make the inflating liferafts separate automatically with sinking boats at the water depth of 2-4 meters, so that the aim of saving life can be achieved.

2. Standards compliant
The hydrostatic release unit comply with the amendment 1996 of 1974 SOLAS convention and the international life-saving applicance n code LSA. MSC. 81(70)

3. The Working of HRU:

a.HRU acts as a connecting media between life raft container and ship deck, where it is stored.

b.The HRU comes in action under the pressure of water exerted on HRU when the ship sinks below 4m of water level.

c.The HRU consists of a sharp knife or chisel which is used to cut the strap lashed over the container carrying life raft, but it still holds the painter at the weak link.

d.The HRU is connected to the container through a lashing arrangement which can be disengaged quickly by means of slip hook when launching the raft manually.

e.The HRU is connected to a strong point on deck through a weak link.

f.When vessel sinks, the HRU cuts the rope and the container floats to the surface of water.

g.As vessel sinks further, the tension in the painter causes the life raft to inflate out of the container.

h.The tension acting on the weak link will cause it to break making the life raft free from the ship.

i.When vessel sinks, the HRU cuts the rope and the container floats to the surface of water.
