3.1 Automatic release mechanism

 When the ship sinks, the hydrostatic release unit actuates at a depth of 2 to 4 m and disconnects the lashing wire from the cradle, and the container floats to the surface of the water. At this time, the operating line tied to the painter is pulled and inflation of the liferaft is started. Next, a weak link fastened to the cradle breaks, so the liferaft is released from the sinking ship and floats to the surface.
