Sažetak
Different types of cargo tanks for gas sea-transport by Liquefied Gas Carriers are described. Design of bilobe tanks, as a complex task, according to the Classification Rules and the USCG Requirements is analysed. This includes selection of special material for high pressure and low temperature, determination of internal pressure consisting of design vapour pressure and liquid pressure that depends on ship motion in rough sea. Furthermore, it includes calculation of tank scant-lings, i.e. shell thickness, and design of longitudinal bulkhead, swash bulkhead, vacuum rings and stiffening rings. Stabil-ity of cylindrical shells and torispherical dished ends is considered. Special attention is paid to the FEM analysis of the stiffening rings. The design procedure is illustrated in case of an LPG Carrier with one ordinary cylindrical tank and huge bilobe tank. Some comments are given how to improve tank design for production.
