Piping Stress Analysis

Hello All,

Can you advice me on what the path into the Piping Stress Analysis profession is? I have a structural engineering background but will like to make a change possibly into Piping Stress Analysis. I recently worked for an EPCM company in Calgary but I've lost interest in the structural side of things. Yet I don't want to throw away my knowledge entirely. Is it possible to be self taught or are there courses available?

Thanks,
Dade
