🔍 Key Concepts

• Construction and purpose of double bottom tanks on cargo and tanker vessels • Typical design and location of access manholes used for entering confined spaces in tanks • Why access points are placed on inner plating (tank tops) rather than hull (outer bottom) plating

💭 Think About

• Think about which surface is safest and most practical for crew to open and enter a double bottom tank while the vessel is afloat. • Consider whether access to a tank is usually through the inside of the ship (internal decks/tank tops) or through the outer shell plating that is in contact with the sea. • Ask yourself which type of closure (hinged vs. gasketed and bolted) is more appropriate for maintaining a liquid-tight, strong boundary under ship operating conditions.

✅ Before You Answer

• Verify where crew would normally stand to open a double bottom tank: on the inner tank top plating or outside on the hull bottom. • Consider which design better ensures watertight integrity: hinged hatches or gasketed and bolted closures. • Eliminate any choice that would require routine access through the outer hull plating while the vessel is in service.
