During the shipping process of LNG ship, crack expansion may occur in the main shield of LNG cargo tank, resulting in LNG leakage into the secondary shield drip tray of type B tank. Due to the large temperature difference between the LNG temperature and the external environment, evaporation and diffusion will occur in the process of leakage to the secondary shield drip tray. When the design of the secondary shield drip tray is unreasonable, the leaked LNG will overflow the drip tray and drip onto the hull, endangering the safety of the hull. Taking a liquid cargo tank of a LNG ship as the research object, this paper uses ANSYS simulation software to simulate and analyze the residual amount after evaporation in the process of LNG leakage to the secondary shield drip tray. The secondary shield drip tray can verify whether it meets the design requirements according to the LNG residue.
