Here are the 2 mods you could have trouble to find:
The SteelViking-HotSoup-WaterDrips (again thanks to Volodya!):

And the Old Style Explosions Baza_FX (DynEnv compatible):
http://www.mediafire.com/download.php?s3ko025bitgu870
All others are easily findable on subsim/google
PS: don't forget to desable the "AI Crew Damage Control" in TDW Generic Patcher (not compatible with AST_SH5_v2)
And i added R.E.M. - hydrophone mute for player fix (TDW compatible), to be able to keep GHG working on surface...should be findable in REM thread if you need it.
(Be aware your hydro guy need some mission experiences + points to be able to detect everything, at least on surface!)
