Construction defect analysis of insulation panels for cargo tanks on liquified natural gas carriers

Detection and inspection of physical defects on newly installed insulation panels of liquefied natural gas (LNG) containment system on LNG ships is carried out in pursuance to the contractual conditions aims at achieving quality, reducing risk and ensuring safety. It is carried out throughout the in...
