Hello,
I am working on an API 650 external floating roof, naphta tank, which will be undergoing change of service from Naphta to Crude oil. In this perspective what things I need to do from an engineer contractor point of view. It is in FEL-2(feed) stage. Below is what I think I need to do:
1- Prepare SOW for tank inspection and integrity company as per API 653. They will do full calculation, i.e. thickness evaluation for new S.G and other requirement. I can do preliminary calculation but final calculation will be done by some certified API 653 inspection company. Kindly advice what normally is the line of action in change of service of tanks, I mean do we have to involve inspection company or just do thickness evaluation myself and tell client its safe to change service. Note that I asked client to provide me with latest UT report so now I also have update thickness report of tank
Regards,
IK
