There is a mod done by TDW (The Dark Wrath) which was used in SH4 and he attempted to adapt it to SH3. It result in CTD on starting up if you had been depth charged prior to your save. It was not compatible with SH3 and no solution was found.
If you are interested in looking at the mod here is a link to it :

It did work well except for the issue with the Save, though.
Good hunting,
