What safety system protects ship structure from cryogenic liquid leaks on deck?
Direct Answer
Option C: Water spray curtain system
Water spray curtain systems are installed on gas carriers to protect the ship's structure from the effects of cryogenic spills. By creating a thermal barrier, the water spray prevents the ship's steel from reaching temperatures that could cause brittle fracture, a vital safety requirement under the IGC Code for deck protection.
