QRH Usage Scenarios

Emergency Disconnection : Vessels experiencing fires require immediate mooring line disconnection to prevent incident escalation.
Extreme Weather Response : Typhoons/sudden gales cause over-tension, risking capsizing/line failure.
Efficient Operations at Automated Ports : Container ships/Ro-Ro vessels require frequent mooring line connections/releases during fast cargo operations.
Safety Protection for Specialized Vessels : LNG/LPG carriers/chemical tankers/polar research vessels operate in extreme/high-risk conditions.
High-Frequency Operations : Tugboats/ferries/fishing vessels require daily repetitive mooring/disconnection tasks.
