According to Wikipedia, the fire occurred because "crankcase split". I
have to wonder what happened exactly, how could the crankcase split,
and if it did split, it must have been a massive oil leak.



I thought ship engines of this size had "open crankcases" with the oil
lines plumbed. I've also been told that being very slow reving
two-stroke engines they sometimes don't have main caps fitted to the
conrods.

Oh - just read some more of the article, it says "a crankcase split"
so it could have been on some small ancillary / genset engine.
