Abstract
A method for preparing a fuel tank for repairs and verifying the repair work using an apparatus is presented. The apparatus is connected to the fuel tank. The fuel tank is purged of oxygen to a certain level using a gas provided by the apparatus until a level of the oxygen in the fuel tank reaches that level. Openings on the fuel tank are closed to the environment. The fuel tank is repaired while the level of oxygen is maintained in the fuel tank. The gas provided by the apparatus pressurizes the fuel tank to a certain pressure level. The pressure level is maintained for a specified period of time. An inspection of the repaired area of the fuel tank is then performed.
