MdRizal, if I understand correctly you propose to insert the studding outlet through the vessel wall, rather than set on the vessel wall.
The former case is governed by UW-16(d)(1), the latter by UW-16(d)(2).
So, yes, design per any of the applicable sketches and associated requirements is permitted.
I am reading from the 2017 Ed, you would need to confirm per 2019 Ed.
