Q

Which is TRUE concerning a hydrostatic release mechanism for a liferaft?

🔍 Key Concepts

• Hydrostatic release unit (HRU) function and purpose on a liferaft • Difference between manual release/inflation and automatic release • Conditions needed for an HRU to activate in an unattended sinking scenario

💭 Think About

• Think about what an HRU is designed to do if a ship sinks suddenly and no one can manually launch the liferaft—how does it ensure the raft can still float free? • Consider whether the HRU has anything to do with actually inflating the raft, or only with releasing it from its securing arrangements. • Ask yourself if the HRU reacts to water contact at the surface, or to being pushed down by increasing water pressure as the vessel sinks.

✅ Before You Answer

• Verify whether the HRU’s job is to release the securing straps or to inflate the raft itself. • Check if the HRU is meant to be open to the sea or kept inside a watertight cover in normal service. • Confirm whether the HRU functions at any contact with water or only after being submerged to a specific depth/pressure.
