The ship houses two steam generating systems at which locations?

• A. MR No. 1 and MR No. 2
• B. Aft Engine Room and Fore Engine Room
• C. No. 3 and No. 4
• D. Main Deck and Lower Deck

Answer: (A)

Two steam generating systems are housed in the two Machinery Rooms, labeled MR No. 1 and MR No. 2. This arrangement provides redundancy and protects the boilers and their systems by keeping them in dedicated, separate spaces. If one boiler room needs maintenance or is taken offline, the other can continue supplying steam for the ship’s needs. The fore and aft engine rooms are where the main propulsion engines live, not the steam generators. Having No. 3 and No. 4 would imply additional boiler spaces that the ship doesn’t have, and decks like the Main Deck or Lower Deck aren’t locations for the steam-generating plant.
