X
HRU plays an important role when it comes to saving life during abandon ship situation. SOLAS 74 clearly specify the requirements for construction and positioning of the HRU at the life raft.
The Working of HRU:
a.HRU acts as a connecting media between life raft container, floatfree EPIRB 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.
