I think they have been building this engine for a while, I have a link saved from 2003. Maybe they finally sold one of the 14 cylinder versions.

Its a 12K98MC eg

Eddie... With my line of work I actually visit the current fleet of Hapag Lloyd vessels which have the 98000 hp 12 cyl. version, your right they are Terrifying straight 12 with 4 turbos the size of 6 x 6 sheds, about 3-4 stories high 2000 liters per pot 24000 liters in total max

180 R.P.M and all through to a single prop , not seen one running yet, the spare piston and conrod weighs about 2-3 tons and is roughly 4 foot in diameter, each of the crankcases has a full size door you can open and walk in to, I will take some pictures next time I am on board.

Interesting thing is the crank. No two pistons move together.

Most marine diesel engines are two stroke and fully reversable, when they want to go backwards they stop the engine and start it in reverse.

Very interesting, but what do they use to start an engine of this size?

Normally started by injecting air into the cylinders, air is controlled by a separate camshaft which also cuts off the fuel to those cylinders while they are being turned over.

It's almost standard for very big diesels now, the largest electric starter motor I have seen were on big Caterpillar diesels and that was a 48V motor.

Then they hang the anchor on it and let go. If the water's deep enough, away they go.
