Seam2_Semi_Final

Which hydrostatic principle best explains why a flooded compartment increases the ship's draft?

• Archimedes' Principle

• Bernoulli's Principle

• Pascal's Law

• Newton's Third Law

During asymmetric flooding, the stability loss is primarily due to:

• Loss of buoyancy alone

• Shifting of the center of gravity and free surface effect

• Reduction in metacentric height due to wind

• Increased propulsion force

The free surface effect can be neutralized by:

• Fully filling or emptying the compartment

• Increasing vessel speed

• Adding ballast high up

• Venting trapped air

When water ingress is limited to a compartment forward of the ship's center of flotation, the expected result is:

• Increased stern draft and decreased forward draft

• Decreased total displacement

• Trim by the head

• Reduced hydrostatic pressure

What happens to the ship's metacentric height (GM) when large quantities of water flood a compartment?

• GM increases due to added weight

• GM remains unaffected

• GM decreases, reducing stability

• GM improves as water adds symmetry

A ship's ability to resist capsizing after flooding depends most critically on:

• Speed of the ship

• Shape of the hull and waterplane area

• Crew experience

• Lifeboat deployment

If water enters a tank longitudinally near midships, it will primarily affect:

• Trim

• List

• Displacement only

• Speed only

When water enters an isolated, unventilated compartment, buoyancy loss is caused by:

• Compressed air creating overpressure

• Added water weight replacing displaced water

• Reduced external water pressure

• Structural stiffeners failing

A ship trimmed excessively by the stern after damage will experience:

• Enhanced maneuverability

• Increased propeller immersion

• Reduced rudder effectiveness

• Higher forward draft

When flooding occurs along the ship's length, longitudinal center of buoyancy shifts:

• Forward

• Aft

• Depends on flooding location

• Stays constant
