I'd give them a couple days.
At best, I'd think it'd take 1 to 2 days. They will want to do safety inspections to make sure all the charges are blown and that it doesn't have any other dangers.
Then they'll want to install moorings balls to keep captains from dropping anchor on other divers heads.
So expect that to take 1 to 2 days, or maybe a little more.
This is all assuming they don't flip it like the idiots sinking the Speigel Grove did.
