Question 1 of 2066636ee728f7522a1c517532

Assuming that the recommended hatch loading sequence is followed, how many long tons of iron ore may be loaded through hatches 2, 6, & 10, while using a single belt loader, to arrive at a desired mean keel draft of 27'-07"? (use the Guidance Manual for Loading M.V. GRAND HAVEN)

🔍 Key Concepts

• Loading manuals/curves for M.V. GRAND HAVEN – how hatch loading sequences relate to final drafts • Relationship between displacement, draft, and tons per inch immersion (TPI) at the target mean draft • Effect of partial loading in selected hatches (2, 6, & 10 only) on overall displacement and mean draft

💭 Think About

• First, determine the ship’s approximate displacement and TPI at the desired mean draft of 27'-07" using the loading manual tables or curves. • Next, work out how much total additional weight is needed to move from the starting condition to the desired draft, then divide by the number of hatches being used. • Use the recommended loading sequence in the manual to see how much weight is normally placed in each of these hatches at or near this draft, and compare that to the per‑hatch tonnage implied by each answer choice.

✅ Before You Answer

• Confirm you are using the correct hydrostatic data (displacement/TPI) for the draft range around 27'-07". • Verify that you are applying weight only to hatches 2, 6, and 10 according to the sequence, and not assuming uniform loading across all hatches. • Double‑check that your computed total added tons ÷ 3 hatches matches one of the per‑hatch values in the answer choices.
