Wow!
Maximum torque: 5,608,312 lb/ft at 102rpm
I wonder how they dyno that.

Maybe it's a computed estimate?
Here's what caught my eye:
Quote:
Fuel consumption at maximum power is 0.278 lbs per hp per hour (Brake Specific Fuel Consumption). Fuel consumption at maximum economy is 0.260 lbs/hp/hour. At maximum economy the engine exceeds 50% thermal efficiency. That is, more than 50% of the energy in the fuel in converted to motion.
For comparison, most automotive and small aircraft engines have BSFC figures in the 0.40-0.60 lbs/hp/hr range and 25-30% thermal efficiency range.
I thought thermal efficiency decreased as size of the engine increased. How is this one so efficient?

I have seen this before. I would like to see the machines that made the crankshaft, pistons and block.

Actually, it can be the other way around.
The larger the engine is, the lower the surface-area to volume ratio. That reduces the amount of heat that can enter the coolant.

The engine employs a system to recover heat and turn it into motion.

Exhaust energy can thus be recovered and applied in
both a steam turbine and exhaust-gas power turbine to
generate electrical power, equivalent to 11 per cent of
engine power. The electrical power can be employed either
in a shaft motor/generator or in supplying shipboard
services. The generated power can thus contribute
significant savings in both fuel costs and exhaust emissions
(CO2, NOX, SOX, etc.). The payback time would depend
upon the installation design and its operating costs, but
would be expected to be less than fi ve years.
The Total Heat Recovery Plant also offers an attractive
possibility for powering the larger container ships which
need more propulsion power than is available from the
14-cylinder Sulzer RT-fl ex96C engine. The standard
engine gives an MCR power of 80,080 kW, thereby
having a continuous service output (85 per cent load) of
68,068 kW. At this engine rating, the Total Heat Recovery
Plant would contribute a shaft power of 7390 kW. Th e
combined service power for propulsion would therefore
be 75,458 kW, equivalent to an engine MCR power of
88,770 kW for a plant without heat recovery

Wow, that is freakin awesome!
I bet they use Mobil 1.

I have torque envy.
102 RPM, probably sees some good pressure on the bearings....probably at least Supertech 15w40...
The oil filter is probably the size of a 40 gal drum....needs a big stinkin oil filter wrench unless they only tightened it hand tight...

Heheh, good one!!
I like that "Note the steps by each crank throw that lead down into the crankcase"!!
'Well, guess I'll walk down and check the bearings....'

I do wonder what weight oil they use in that thing.
Most likely a 0W20
Seriously, The rule of thumb is that the slower the engine, the greater the loads, the higher the needed viscosity. A 50 or 60 weight comes to mind here.
Dig the electric motor in the LL corner. Someone said it was for ventilation. Anyone know for sure?

Its possible its for ventilation around the engine, hard to say for sure since the installation is not complete. I'm not a marine diesel expert so I'm hardly certain of any thing but I can see a valve to the right of the motor. I'm thinking its part of a chill water circulation system for the engine. The engine room should have large air handlers that are providing the ventilation power from the outside of the ship. The engine room should be able to have positive and/or negative pressure depending on the situation.

Never gets old. 
Even though it gets reposted all the time.

I knew a guy that worked on the huge desiel engines on Navy ships he told me that these ships also run the same oil for life. So they leave the ship yard with a lifetime fill.
I find it amazing that this ship probably burns more gas on 1.5 hours than the local gas station has in their tanks.
This engine burns more fuel on startup than I probbaly will burn in 3 months of driving my truck.
