Problem
The client possessed an above-ground storage tank for crude oil that had a leak resulting from a spreading lap weld. In addition, the tank had several temporary epoxy patches in place. The original plan was to take the tank out of operation for repairs. However, due to business circumstances, it was necessary to keep the tank in service. As a result, the temporary patches were expensive and demanded considerable maintenance time and resources.
(The customer had a crude oil above ground storage tank (AST) with a spreading lap weld leak. The tank also had several other temporary epoxy patches. The company planned to take the tank out of service to make the repairs. Business conditions required that the tank remain in service. Temporary patches to the tank were costly and required significant maintenance time and resources. )
Solution
Forge Tech Inc. (FTI) came up with a fresh, patented solution that eliminated the need to shut down the above-ground storage tank (AST). The team installed deck plates over each leak, as depicted in detail on the following page. The PFB application utilised by FTI bonded metal studs at a low temperature, which prevented the production of sparks or flames and did not generate sufficient heat to qualify as “Hot Work” under the API-2207 classification. Consequently, this innovative remedy enabled the tank to be fixed without necessitating its decommissioning or degassing.

The FTI team installed deck plates over each leak as shown in detail on the next page. The PFB application bonds metal studs at a low temperature that does not produce any sparks or flames and does not generate enough heat to meet the API-2207 definition of “Hot Work”.
This revolutionary solution allowed the tank to be repaired without having to be decommissioned or degassed.)
Results
Permanent seals installed on all tank leaks. Tank remained in -service without process interruption.
