Nonlinear impact response analysis of LNG FPSO cargo tank structures under sloshing loads

Author(s): Sang Eui Lee, Bong Ju Kim, Jung Kwan Seo, Yeon Chul Ha, Toshiyuki Matsumoto, Su Hwan Byeon and Jeom Kee Paik

 

Abstract:
This is a sequel to a previous paper by the same authors, which proposed a probabilistic approach to determine the nominal values of tank sloshing loads in the structural hull design of liquefied natural gas, floating production, storage and offloading units (LNG FPSO or FLNG). This study presents a procedure for the numerical computation of nonlinear impact responses in FLNG cargo tank structures under sloshing loads. The computations are performed using ANSYS/LS-DYNA nonlinear finite element software. Applied examples using a hypothetical FLNG are presented. The insights and conclusions obtained from the study are documented.
