  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:

  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.

  FYI, the Queen Mary II is equipped with 4 x Wartsila 16V46C engines driving generators. (the propellers are driven by electric motors). Each genset produces 16.8 MW, or, in terms of horsepower, about 22,500 HP, for a total of 90,000 HP or so.
  
  Also FYI regarding the engine pictures above, only the photo of the whole engine is an RTA 96C. The other shots of the bedplate and crankshaft, pistons, etc. are not from a 96C. Not that it matters much, because they look very similar.

  Need some help. This engine is too big for my boat!
  In a smaller scale, I have an Internet site where I put some Cargo looking vessel virtual pictures. I need some Professionnal Seamen's vision and approach to have a judgment on those pictures.
  Would you please visit my site and give your opinion?
  Thanks in advance and my best regards.
  Eric.

  Hello Together,
  Sorry to tell you but in the artical are some facts wrong. The first 14cylinder are built in Korea by Doosan and not in Japan. The engien isn't anymore a convential engine Type RTA but a RTflex like as a commenral diesel engine as in our cars.
  Maybe some facts more for you the length of the engien is 27,3m and 13m high. the stroke is recorded with piston stroke of 2,5m and a max revolution of 102rmp.
  Regards Marco
