Worlds First LNG Cargo Container Ship Cryogenic Degassing Services A shipping company built a cargo container ship that is fueled by liquefied natural gas (LNG). Valve repairs needed to be completed on the fuel tanks aboard the ship. In order to do so, each tank would be taken out of service, degassed with a 42 MMBTU thermal oxidizer and then displaced with N 2 . The technical challenges surrounding this project included temperature at which LNG is stored at (-260 °F), liquid carryover, the pressure at which the fuel is stored (80 PSI), and the allowable temperature limits of the carbon steel components. Understanding the nature of cryogenic materials, LNG would have to be heated to the minimum allowable temperature of the knockout pot and high pressure regulator of -20 °F. This required s
