Abstract
Provided herein are systems and methods for achieving an extended service life for a pressure vessel that has experienced a prior service life. In some embodiments, the service life of the vessel has expired. The service vessel has an unknown damage condition, including defects sustained during the service life. Despite these defects and unknown accumulated damage state, the embodiments described herein may be used to test these vessels, to safely pressurize the vessels beyond pressures deemed safe for the vessel to experience in its damaged state, and to recommission a new service life for the vessel. The recommissioning of the vessel for an additional service interval may include meeting certain requirements for the pressure vessel, and embodiments described herein include exemplary measurements and observations to assure these requirements of the rejuvenated vessel are met.
