What is the primary function of the ship's eductor in damage control?

• A. To remove water from compartments by creating a vacuum or jet effect
• B. To pump fuel
• C. To measure pressure
• D. To patch leaks

Answer: (B)

Dewatering flooded spaces with a motive-fluid jet. The eductor uses a push of steam or compressed air to create a high-velocity jet that entrains surrounding water, producing suction at the mouth and drawing water from the flooded compartment into a discharge line or pump. This rapid removal of water is exactly what you need in damage control to restore buoyancy and stability. It isn’t used to pump fuel, measure pressure, or patch leaks, so those functions belong to other equipment or procedures.
