I've never, not one single time, had a Ship Chunk drop in A15. Looking at the incidentdefs, the shipchunkdrop event has no baseChance, so I don't think it can ever occur - except that it also had no base chance in A14 and it did occur then.
Edit: we've at least confirmed that Cassandra drops ship chunks, but I still suspect Randy doesn't, so I've updated the title
It occurs for me all the time ._.
^Chunks or Parts? They are different.
I sort of half remember seeing a ship chunk message in A15 at one point, but I might be mistaken.
They certainly aren't common.

They occur on 1st scenario. Will never occur on tribal scenario. only it will uccour in tribal if seeded scenario says so or yoiu edit the scenario
I just got it. It is definitely linked to your (or the map's) available metal and/or component supply.
I created a new colony, dev tooled away all the metal and components (and the scenario-gifted ship chunks) and then just waited on fast forward for a few days. Had to wait for 5 days, but it came sure enough. This was on Cassandra Base-builder for those who care.
That would make sense some.
I have a (massive) supply of steel and components, and have never seen a ship chunk event.
That being said, in (I believe it was his anyways.) Dan Gheesling's A15 playthrough, he had a ship chunk drop a week or two ago.
Interesting, that would explain things.
I couldn't find any sign of code that might increase the frequency of ship chunks based on steel or components on the map. But I did figure out that Randy won't drop chunks. Thanks for helping me narrow it down!
