Design of LNG Tank Type C

Cylindrical tank-type C is designed for cruise passenger ships trying to adopt hull space and to meet the requirements of propulsion. Tank must be a double shell with the vacuum space in between, which is also fulfilled with the perlite as insulation. The main input for the design was tank capacity of 430 m3, vapor pressure, and hull structure. Trying to satisfy volume capacity different dished end of tank was observed. According to classification rules, DNV and IGC rules tank thickness, supports, stiffening and vacuum rings are determined to satisfy bending and buckling requirements. Finite element analysis was used to verify the given results. According to the given results space for improvements of tank-type C was observed.
