ABSTRACT

Liquefied natural gas (LNG) is increasingly used in marine propulsion and transport, with cargo tanks being a critical component affecting vessel safety and efficiency. Existing studies on conventional LNG carriers and LNG dual-fuel vessels have focused on typical independent tank types (A, B, and C), examining their structural characteristics, load-bearing mechanisms, and application scenarios. LNG carrier tanks are designed for large-volume, long-term storage with emphasis on low-temperature performance, fatigue resistance, and deformation control, whereas dual-fuel vessel tanks prioritize safety, compactness, and flexible arrangement for fuel supply. Current research combines theoretical analysis, numerical simulation, and regulatory comparison to evaluate tank mechanical responses and thermal behavior under low-temperature, pressure, and wave-induced loads[1]. Type C tanks, particularly the bi-lobe double-tank configuration, are highlighted for their excellent pressure resistance, insulation performance, and space utilization, making them the preferred choice for small- and medium-sized dual-fuel vessels. These studies provide important references for tank structural optimization, material selection, and safety assessment, while also offering methodological guidance for future integrated LNG fuel system design and lightweighting research.
