D) Easy Operation & Less MaintenanceD) Easy Operation & Less Maintenance--Simple Pressure Control, Independence from HullSimple Pressure Control, Independence from Hull--• To operate continuously without dry dock during long life time
• No special pressure controls
• To operate continuously without dry dock during long life time• To minimize risks to stop FLNG operation
• No special pressure controls
Strong against OUTER and inner pressurepressure
• Free from inner hull damagegSeawater leakage from ballast tank, if it should occur, can be treated safely
