Here is my design for White Star's planned-but-never-completed OCEANIC III of 1928. I made her about the same size and speed as Normandie and Queen Mary, and is White Star's contender for the Blue Riband. She would have been the first (and only) ocean liner to win the Blue Riband using diesels instead of the more traditional steam turbines. I also added the passenger numbers, cabin arrangements, and estimated wartime troop capacity at the bottom of the report. Here she is, in all her glory.

MV Oceanic III - White Star's Blue Riband Contender

Gross Tonnage: 81,465 gross tons (which would make her bigger than the Queen Mary and Normandie , but smaller than the Queen Elizabeth )

Machinery:
• Diesel Internal Combustion Generators
• Electric motors, 4 shafts, 200,000 shp / 149,200 kW = 30.69 kts
• Range 9,000nm @ 28.50 kts
• Bunker at max displacement = 30,493 tons (Diesel Oil)

Crew: 2,039 - 2,651

Cost: £9.602 million / $38.407 million

Distribution of weights at normal displacement:
• Machinery: 6,227 tons, 9.6 %

o Above deck: 800 tons

Overall Survivability and Seakeeping:
• Survivability (Non-critical penetrating hits needed to sink ship):
o 189,351 lbs / 85,888 kg = 1,753.2 x 6 " / 152 mm shells or 8.5 torpedoes

Hull Form Characteristics:
• Hull has a flush deck, a normal bow and a cruiser stern
• Block coefficient (normal/deep): 0.600 / 0.619
• Length to Beam Ratio: 8.76 : 1
• Hull Speed: 42.79 kts
• Power going to wave formation at top speed: 44 %
• Trim (Max stability = 0, Max steadiness = 100): 45
• Bow angle (Positive = bow angles forward): 9.46 degrees
• Stern overhang: -5.00 ft / -1.52 m
• Freeboard Breakdown (% = length of deck as a percentage of waterline length):
- Forecastle: 20.00 %, 48.00 ft / 14.63 m, 46.00 ft / 14.02 m
- Forward deck: 30.00 %, 46.00 ft / 14.02 m, 46.00 ft / 14.02 m
- Aft deck: 35.00 %, 46.00 ft / 14.02 m, 46.00 ft / 14.02 m
- Quarter deck: 15.00 %, 46.00 ft / 14.02 m, 46.00 ft / 14.02 m
- Average freeboard: 46.16 ft / 14.07 m

Ship Space, Strength and Comments:
• Space - Hull below water (magazines/engines, low = better): 53.8 %
- Above water (accommodation/working, high = better): 373.5 %
• Waterplane Area: 86,910 square feet or 8,074 square meters
• Displacement factor (Displacement / loading): 209 %
• Structure weight / hull surface area: 151 lbs/sq ft or 736 kg/sq meter
• Hull Strength (Relative):
o Cross-sectional: 0.92
o Longitudinal: 2.07
o Overall: 1.00
• Excellent machinery, storage, compartmentation space
• Excellent accommodation and workspace room
• Ship has slow, easy roll, a good, steady gun platform
• Excellent seaboat, comfortable, rides out heavy weather easily

Troop Capacity (wartime): Assuming a WW2 timeframe of 2 tons/soldier and his equipment, it looks like my ocean liner MV OCEANIC III would be able to carry approx. 9,400 soldiers at one time.

Passenger Capacity Calculations: • First Class Passenger: requires 17.12 tons/passenger, used 20 tons/passenger
• Second Class Passenger: requires 9.12 tons/passenger, used 10 tons/passenger
• Tourist Class Passenger: requires 3.18 tons/passenger, used 3.5 tons/passenger

Miscellaneous Weight Breakdown:
• First Class Passengers….. 398 passengers * 20t/guest = 7,960 t
• Second Class Passengers….. 536 passengers * 10t/guest = 5,360 t
• Tourist Class Passengers….. 1,028 passengers * 3.5 t/guest = 3,600 t
• Total Passengers = 1,962 passengers = 16,920 t
• Cargo…. 1,400 tons
• Extras…. 480 tons
• Grand Total…. 18,800 tons

Guest Space Ratio (grt/guest) = 41.5 tons/passenger
