Requesting help regarding collision damage

I was wondering if any modders here have figured out what controls collision damage regarding land. The reason I ask this is because I am trying to stop the damage the boot sometimes takes while sitting on the sea bed floor while trying to repair over many hours (during high time compression) when running my longer repair times mod. It's strange, because sometimes the boot will take damage, and other times it won't. Each instance is different. I thought that a work around might be to slow down the sea currents, but when I did this, there was no change to the damage. Does anyone have any clues or advice on a fix for this? I know the collision file contains what I need to change, but unfortunatley it's hard-coded.
