Vertical shell joint 5t offset
Vertical shell joint 5t offset
(OP)
Section 5.1.5.2 states an offset of 5t is required between adjacent shell courses. Does API allow this 5t offset requirement to be eliminated if the shell courses are shop welded.
We fabicate many SS vessels. We will purchase 48" wide sheets and shop weld the sheets together to create a 96" wide sheet for field installation. I had heard through the grapevine that API had modified this 5t requirement for certain thicknesses but I haven't been able to find anything to back up that claim.

You can always seam your sheets into 96" wide plates and then notch both ends about 6" to stagger your verts. You would only loose 6" per sheet length. Might make everybody happy.
