Completion of ASME VIII Div 1 Vessel in the Field
Completion of ASME VIII Div 1 Vessel in the Field
(OP)
Our transportation dept has informed me a Section VIII vessel we have on order might be too large to ship in one piece. The final weld (for pressure boundary) would have to be completed in the field. The weld exam, hydro, and application of the U stamp would have to be done in the field as well.
I was wondering what some of the issues/logistics we may encounter if we do this. The only other foreseeable (but not necessarily viable) alternative is to cancel the order and order 2 smaller vessels instead of one.

field contractor can put together and apply r stamp
or
vessel build in 2 halves and issue 2 partials
field contractor weld together and issue u stamp
in the latter case...field contractor will have to use fabricators calculations and approve them
we have done several with shop completion and field applied r stamp
no biggie
match mark....fit up guides and round up rings
