@KapteinOpel yep! I-6, I-8, I-9, V-12, and V-16 diesel engines are available from Rolls Royce Bergen Diesel, and they're all made in Bergen, Norway. Even the cylinder blocks are forged locally.
@joffeloff I like that. :) They should make smaller engines also, suitable for smaller boats and maybe for trucks and other machinery. I would like to see a 100% Norwegian-built Moxy. :)
@Squarerig They have what is called a lube oil 'priming pump' that circulates oil before start-up. Once the engine runs, however, a larger pump that is driven directly by the engine takes over lube oil circulation duties.
I wonder if these power units could be used in Diesel Locomotives such as the British Class 60? I know Ruston Paxman used to make marine units which were used in locomotives as well, but as I am hoping to preserve a Class 60 in the next 5 years and I am looking at replacing the unreliable Mirrlees MB275T with a Rolls Royce Bergen unit.
@EWS60008 i don't know. they would have to be very large locomotives. Those Paxman engines are quite a bit smaller than these, and I think they run a bit faster too.
@douro20 Bergen Diesel started out as an independent engine manufacturer, at a time when there were a lot of them in Norway. They were bought out by a Norwegian maritime conglomerate called Ulstein, who were branching out doing everything from ship design and construction to electronics, thrusters and engines. In the end I suppose it didn't work out, and RR bought both the engine and thruster divisions.
Also, not a segmented *crankshaft*, but a *camshaft*. You read too fast. :p
@douro20 Oh. ._. It is common for the crosshead engines to have cranks that are constructed by fitting together pieces, so I figured that's what you meant.
Segmented camshafts are common on current designs of medium-speed and even some high-speed engines, provided they're sizeable enough. (MaK, Cat, Jenbacher, MAN, etc)
Looks almost real !
Which computer CAD program made this ?

these engines are amazing! we have two of these as main engines on the boat i work. the anchorhandler M/V Far Scorpion!
it puts out 4500 kW! but we also have a 3000 kW PTI-engine to increase our bollard pull

Are engines of this size equipped with an auxiliary lube oil pump or do they rely on the engine itself to supply lubrication?

I thought they only used segmented crankshafts in much larger engines.

I haven't been able to find anything on the Bergen division. Did it start out as a division of Rolls-Royce or did start as an independent company?
