WBT 01 Tower
Cause: Small hole on WBT 01 Tower. This is an absorber tower which contains flammable gas. On examining the hole in the tower they shut it down.

Followup: No

Notes: Immediately feed was cut out of the tower, water spray was applied to the leak to help minimize the vapors, and the weep hole was plugged. The area surrounding the leak was ultrasonically tested and found to be of acceptable thickness. A more intense UT scan was performed over the entire vessel and confirmed to be of acceptable thickness. The leaking tell-tale hole was plugged per mechanical design standards. About 1/3 of the vessel is being sand-blasted and visually inspected to verify that there are not any unplugged tell-tale holes remaining.
