Which part of the float-free arrangement for inflatable liferafts is made to release the liferaft after being automatically inflated during the ship is sinking?

Answer 1

The part of the float-free arrangement for inflatable liferafts that is made to release the liferaft after being automatically inflated during the ship sinking is the hydrostatic release unit (HRU). The HRU is designed to automatically release the liferaft from its cradle or storage position when it is submerged to a certain depth, typically around 1.5 to 4 meters. This ensures that the liferaft is deployed and inflated even if the ship sinks rapidly, allowing it to rise to the surface and provide a means of escape for the crew.
