What is the primary cause of cold spot formation on the outer hull plating near an LNG tank?
Direct Answer
Option A: Insulation failure or leak in cargo containment
Cold spots on the outer hull indicate a failure in the cryogenic insulation system or a leak in the primary containment barrier. Per IGC Code safety standards, this is a critical condition requiring immediate investigation, as it threatens the structural integrity of the hull steel due to brittle fracture.
