While in dry-dock, what means are provided for completely draining the double bottom tanks in preparation for inspection?

🔍 Key Concepts

• Difference between access openings (for people) and drainage fittings (for liquid)** • How a vessel in dry-dock gets remaining water or sludge out of double bottom tanks • Which fittings are specifically designed to be opened in dry-dock so liquid can discharge externally

💭 Think About

• Which one of these choices would actually let liquid flow out of the tank to the outside when the ship is sitting in dry-dock, without needing pumps? • Are manholes, sounding tubes, or stripping eductors normally used to physically drain a tank in dry-dock, or are they mainly for access, measurement, or pumping? • Think about what is installed at the lowest point of a double bottom tank specifically for drainage when the ship is dry. Which option best fits that role?

✅ Before You Answer

• Identify which option is meant for access for personnel vs. measuring level vs. pumping vs. gravity drainage • Confirm which fitting is normally opened only when the vessel is in dry-dock, not at sea • Focus on what would let the tank completely empty by gravity when the hull is supported on the blocks
