🔍 Key Concepts

• Use the white pages for SS AMERICAN MARINER that deal specifically with one‑compartment standard and minimum permissible GM after flooding. • You must combine the given cargo weights by vertical center of gravity (KG) to find the ship’s initial GM before any double‑bottom loading. • Then use the double‑bottom tank data (capacities and KG/KB values) to find how much liquid you must add so that, after assumed flooding, the GM still meets or exceeds the required value.

💭 Think About

• From the white pages, which flooding condition applies to this question (which compartment is assumed flooded) and what required GM does that standard specify? • Based on the cargo distribution, is your initial KG too high or too low compared with the required maximum allowable KG for the one‑compartment condition? How does that tell you whether you need more or less liquid in the double bottoms? • When you add liquid in the double bottoms, how does that change the displacement and the combined KG? Can you set up an equation for final KG and solve for the unknown tons of liquid?

✅ Before You Answer

• Be sure you are using the correct KG values for each cargo layer (deck, upper tween, lower tween, hold) from the SS AMERICAN MARINER tables – don’t assume or estimate heights. • Verify you are using the right damage case/curve in the white pages – one‑compartment standard for the appropriate draft and load condition. • After solving, recompute the final GM (or compare final KG to the allowable KG) to confirm it meets or just exceeds the one‑compartment standard before choosing among the answer options.
