Never Sea Land brings us the largest engine ever built:
The Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine is the most powerful and most efficient prime-mover in the world today. The Aioi Works of Japan’s Diesel United, Ltd built the first engines and is where some of these pictures were taken.
It is available in 6 through 14 cylinder versions, all are inline engines. These engines were designed primarily for very large container ships. Ship owners like a single engine/single propeller design and the new generation of larger container ships needed a bigger engine to propel them.
The cylinder bore is just under 38″ and the stroke is just over 98″.
The largest piston in the world!
More Enormous Piston Rods.
“DU-Sulzer 12RT A96C” translated to “One large MFD”
How it works.
Smile, I like it!
So you’re wondering what this behemoth powers… right? Nothing less impressive than the Emma Maersk!

Emma as she looks from the sky.
A Comparison of the 
World’s Largest Ships (from the Wall Street Journal) . We hate to tell the world’s premier business newspaper they forgot one… bu they did. Larger than Emma is the The Ultra Large Crude Carrier (now an FPSO) Knock Nevis... formerly known as Seawise Giant, Happy Giant, and Jahre Viking.
Think that’s impressive…. what if she ever caught fire??
SHE DID!

Not nearly the biggest ship! I’ve sailed 300,000 tonners myself which drew 72′ of water. They were a little shorter at 1100′ but 190′ wide and 30′ deeper when loaded and they were considered VeryLargeCrudeCarriers not even UltraLargeCrudeCarriers! If you add the tonnage of the biggest Aircraft Carrier to all it’s supporting vessels, it doesn’t make 300,000 tonnes let alone the 400,000 tonnes of the ULCC’sor the 564,763 tonnes of the Knock Nevis!

They did mention the Knock Nevis at the bottom of the post but they should change the article title.

You are both right… I’ll edit the Article title.
In related news… Stranded has a good article showing how these pistons and cylinder liners are reconditioned:

I would like to kno waht companie can produce such a crankshaft.

When I attended the one hour presentation during the transatlantic crossing aboard the Queen Mary II, I could find out nothing about the powerplant not even if it was turbocharged or a two stroke, much less the manufacturer. They laughed off my questions as too technical. They should be ashamed of themselves. I appreciate your publication of the technical data. Thanks .

Thanks for the kind words Doug. We are considering a cruise ship section here on gCaptain that would be written by mates and engineers aboard these ships. I think we have a real opportunity to give cruising enthusiasts a behind the scenes look at these amazing ships. Stay Tuned.
