Analysis of Stress Field of Fuel Storage Tank Saddle on LNG-fuelled Ship

摘要

This paper introduces fuel storage tank arrangement and the saddle structure of 296600 tons oil tanker (VLCC). According to the relevant standard, using ANSYS software, finite element modeling of the saddle and nearby hull structure is created. The radial force distribution function of the saddle is deduced under various conditions. The accurate stress state for saddle and nearby is found out by the application of finite element direct calculation method. Through the analysis of the results, the improvement measures are given and the reference for the saddle structure design is provided.
