«Deck Management LNG Tanker» subject includes theoretical and practical information about advanced training for work on any type of vessel. This test assesses knowledge and skills required for advanced operations on LNG carriers. It covers critical topics such as cargo handling, gas containment systems and emergency procedures specific to liquefied natural gas transport. Candidates must demonstrate proficiency in deck operations, safety protocols and risk management related to LNG hazards. Practical simulations include real-world scenarios like leak response, vapor dispersion control and emergency shutdown drills. The exam evaluates understanding of LNG properties, including boil-off gas management, pressure control, and flammability risks. Compliance with international regulations (IGC Code, SOLAS) and environmental protection measures is a key component of the assessment. Crisis management, crew coordination and decision-making under pressure are tested to ensure operational readiness. Successful candidates receive certification qualifying them for advanced roles on LNG tankers and other gas carriers.
