Dear Richard Ay,

I am really very thank you for your reply and agreed your point. My issue, it is existing vessel/tank and unreachable area, also there is no data available at present condition. Existing tank, gas outlet piping support is taken from tank shell (Bracket support) and some crack has been found on tank shell, where the gas line pipe support is taken from shell.

I have done detailed pipe stress analysis with considering all possible operating conditions and arrived the loads at this pipe support location. These loads forwarded to civil for new bracket support design and civil provided reaction loads, where the RF pad is attached to tank shell.

Kindly advise me, As per CAESAR II WRC107 analysis, will be able to check the tank local stress for RF pad attachment with considering the civil reaction loads.

Also please find the attached crack photocopy for your ready reference.
