….so as to cause violent water hammering of the drum inlet line…..
This does not sound like a good idea.
Your inlet line should be clean after the steamout to fractionator & blowdown.
Do you inject steam before the drum switch ?
Since you have a “hat”, I guess that you remove the bottom head (manually or remotely) to remove the coke from the drum. You should be able to inspect it to see if it is plugged.
