[MW:16385] RE: 16377] TANK BOTTOM PLATES OVERLAP

Dear Lassaad

first you should inspected it visually. Specially you pay attention to
important area such as sumps, three-plate laps, arc strikes, temporary
attachment removal areas.
Then All of bottom plate overlaps shall be tested by VBT(vacuum box test).

Also you can see 7.3.3 from API 650(2007).


Best Regards,
Farhang
