Liquefied Petroleum Gas (LPG) and Liquefied Natural Gas (LNG) carriers are ships with distinct characteristics: they carry liquefied gas either pressurized, refrigerated or both at the same time, and have special cargo containment systems of various type and complexity. In particular, type C tanks are independent tanks of spherical and cylindrical shape, designed and built as conventional pressure vessels. Corresponding, relatively low utilization of hull volume makes a single hull design of such ships common and a question of their crashworthiness arises.A typical LPG ship was considered and nonlinear FE method applied in the present crashworthiness study. A variety of parameters, such as impact location and collision speed, are altered and their effects in collision are studied. The application of space-saving sandwich hull structure was proposed and analyzed in the attempt to improve the concerned ship performance in the collision event. © 2013 Taylor & Francis Group.
