Abstract

Type A LPG Carrier is the ship using the low temperature independent cargo tank separate from the hull, which has various support structures for laying independent tanks on the hull. In this paper, the direct strength analysis for the support structures has been performed through the direct load analysis, load transfer, stress analysis and strength assessment. Also, a rational modeling method of support structures has been proposed to obtain the dynamic load between the hull and the separate tank.
