Question 1 of 205eccef9ebacbc34ba4d461e2

As chief engineer of an oceangoing passenger vessel, it is important to know the effect of trim and stability of your ship in the event of damage to a compartment. To minimize the impact of flooding in the event of a grounding, what should be your ship's safe practice regarding watertight doors and hatches?

🔍 Key Concepts

• Watertight subdivision on passenger ships and why doors in bulkheads are critical in a flooding or grounding casualty • SOLAS and 46 CFR requirements for the status of watertight doors during navigation on passenger vessels • The difference between procedures when underway (navigating) versus anchored or in port

💭 Think About

• Ask yourself: In a sudden grounding with unexpected flooding, which practice gives you the best chance to limit the spread of water immediately, without needing extra actions by the crew? • Consider how quickly flooding can progress after hull damage. Would you want to rely on the crew having time to move around first, or on the ship already being in a protected configuration? • Think about regulatory intent: Are rules written to prioritize convenience of movement for crew, or integrity of watertight boundaries when the vessel is actually at sea?

✅ Before You Answer

• Identify which option clearly states the status of watertight doors during navigation (when a grounding risk is highest). • Eliminate any options that would normally leave watertight doors open at sea, since that would promote flooding between compartments in a casualty. • Confirm that the remaining option still allows doors to be opened when necessary for work, but requires that they can be immediately re-closed.

Question 1 of 20

All watertight doors in subdivision bulkheads shall be kept closed during navigation except when necessarily opened for working of the vessel, and in such cases they shall always be ready to be immediately closed.

All watertight doors in subdivision bulkheads shall be kept closed when the vessel is anchored except when necessarily opened for working of the vessel, and in such cases they shall always be ready to be immediately closed.

All watertight doors in subdivision bulkheads shall be kept open during navigation to facilitate crew movement and in all cases they shall always be ready to be immediately closed.
