Deck General USCG Question #5039 (Set 156)

The DEEP DRILLER, at 58.0 feet draft in sea water, places 200 long tons on board. What is the new draft?

Official USCG Answer & Rule Citation

Correct Answer: Option B — 59.45 feet

Applying fresh weight additions to a floating MODU utilizes the unit's hydrostatic TPI (tons per inch immersion) or displacement curves, where adding 200 long tons at a 58.0-foot draft increases the vessel displacement and alters draft to 59.45 feet.
