Mastering LNG Tanker Operations and Marine Engineering Systems is a comprehensive, practice-driven course designed for marine engineers, deck officers, superintendents, and shore-based professionals working with LNG carriers. From fundamentals to advanced systems integration, you will learn how LNG cargo is safely contained, transferred, cooled, reliquefied, and used as a fuel, while complying with global safety and environmental standards. The curriculum dives deep into tank technologies (Moss and membrane), insulation and thermal performance, boil-off gas generation and handling, cryogenic piping, and automation. You will master end-to-end cargo operations—pre-cool, loading, gas return, temperature and pressure control, discharge, inerting, and purging—along with port operations and ISO 20519 bunkering practices. The course also covers dual-fuel engine operations, onboard power and utilities, emergency shutdown systems, hazardous area equipment, and alarm strategies. With case studies, checklists, and knowledge checks throughout, you will build confidence to diagnose faults, optimize energy balance, and maintain compliance under SOLAS, MARPOL, IGF/IGC Codes, and class rules. Whether you are stepping onto your first LNG vessel or advancing into technical leadership, this course equips you with the competencies to run safer, cleaner, and more efficient LNG tanker operations.
