In order to evaluate the accuracy of stress analyses those are employed in hull structural design of double hulls VLCC as ordinary method to assess the strength, stress measurement of typical parts during hydrostatic structural test was carried out. Using finite element models employed in the design work, those are hold part model and fine meshed detail models with shell elements, re-calculation was made with the same loading as the hydrostatic structural test. After comparison of the test result and calculation result, it was confirmed that current stress analysis methods have enough accuracy for strength assessment for hull structural design. Additional detailed stress analysis of hopper knuckled part with solid element model was conducted, and distorted stress distribution in the vicinity of weld bead was confirmed.
