- Abstract
- The？process？gas？piping？of？the？offshore？plant？can？cause？a？massive？explosion？if？the gas？leakage？occurs？during？operation.？For？the？purpose？of？precaution？of？gas？leakage accident,？an？air？pressure？test？is？performed？on？the？process？equipment？tests？using？a？test pump？as？much？as？the？power？to？the？piping？inner？side,？mix？99%？nitrogen？gas？and？1% helium？gas.？The？purpose？of？the？air？pressure？test？is？to？check？the？work？conformity process？by？handling？and？regulation？for？initial？piping？process,？assembly,？installation？of module,？welding,？center？alignment？of？the？pipes？assembling？flange？gasket？in？an unrestrained？free？state.？In？this？paper,？the？regulation？of？the？problematic？air？pressure test？was？analyzed？and？the？solution？criteria？were？established.？And？leakage？tests？of existing？equipment？were？performed？applying？these？solution？methods.？As？a？result,？it was？confirmed？that？there？was？no？problem.
