[QUOTE=Starbuck1;61553]The only cross section I’ve found of the Costa Concordia’s hull (http://www.cruiseplanet.co.jp/pdf/costaship/concordia.pdf) shows 16 watertight compartments. I’ve assigned the engine rooms to the two directly below the stack, about 250 feet from the stern. Numbered bow to stern: #1 Bow Bulb, #2 Bow Thrusters, #3(?), #4(?), #5(?), #6(?), #7(?), #8(?), #9 (control/electrical room?)(holed), #10 (forward engine room?)(holed), #11 (aft engine room?)(holed), #12 (motors?)(holed), #13 (shafts)(holed), #14 (shafts), #15 (stern thrusters), #16 (rudders).

Thanks for your informative post.
The following link may help visualize the engineering spaces of Costa Concordia. It specifically deals with Costa Victoria, an older ship.

Another interesting link deals with a sister ship, the Carnival Splendor:

Propulsion System:
The diesel-electric propulsion system of the Carnival Splendor consists of two banks (three in the forward and three in the aft engine room) of Wärtsilä 12V46C four stroke diesel engines each rated at 12.600 kW driving (2) converter type motors (2 x 42 MW) from Converteam (ex Alstom), France.
