Mesaieed Tank Farm Inspection Plan

The document outlines an inspection and test plan for pre-repair inspections of crude oil tanks, a firewater tank, and a vessel. Key activities include: 1) MFLT and UT inspections of tank floor plates and annular plates to identify remaining thickness; 2) VBLT of floor plate and annular plate welds and shell-to-bottom welds to check for leaks; and 3) MPI of ring joints, floor sump welds, roof leg welds, and shell nozzle welds to check for defects. The inspections will be performed per approved procedures and qualified personnel, with reports generated meeting API and client specifications.
