Reply To: ACC Leak/Performance Issue


It sounds like you’ve done a good job of chacking teh ACC, but when I say check upstream I actually mean in the steam bypass lines, any drains leading to the ACC, etc. Basically anything that connects to the ACC and follow it to its source to check a valve isn’t left openm, a flange has become loose, etc.

In my experience, air leaks are as likely to be in the BOP piping and equipment that connect to the ACC rather than the ACC itself.
