Abstract

Recently, the LNG ship industry is also developing technology due to increased demand in shipbuilding. LNG is the cause of accidents due to the risk of explosion. Therefore, flame proof enclosure structure (FPES) was studied as a form for the purpose of integrating the design of gas supply devices and detecting gas leakage. We intend to model and complement products of advanced countries overseas. It was proposed to change the shape of an ellipse due to the risk of stress concentration in products of advanced companies. Through structural analysis, the proposed FPES internal pressure performance evaluation was verified and compared to products of advanced companies. The proposed FPES is believed to be able to withstand an internal pressure of about seven times that of advanced companies.


Keywords: LNG ship, Flame proof encloser structure (FPES), Stress concentration, Structural analysis
