API 650 Bottom plate testing
(OP)
I need to Know if it is necessary to re do hydro test after repairing a weld where water leaked during the hydro test.
Is it possible to apply vacuum test in the affected area as defined by chapter 7 point 7.3.3 instead of the hydro test.

Last resort is a rehydro. That test is, as IFRS said, to stress-test the shell. It shouldn't be required to find floor flaws. Did you witness the initial vac-boxing of floor?* It is time-consuming and is brutally hard work. Portions of the floor may have been missed.
* It is hard to expect 100% coverage if we are unwilling to participate, or witness testing.
