What Stock Surge Chest Repair Solutions Were Offered?

SVI installed a new 30” manway. SVI pumped the four active leaks on the exterior walls.

Moving forward, SVI recommended ongoing monitoring of the recessed joints throughout all the interior walls and on the floor. The 53-hollow sounding tiles on the exterior wall only need monitoring at this time. SVI recommended scheduling a re-inspection of this vessel during the 2021 outage.
