Last year, D/W 445,000 T.U.L.C.C. which has horizontal main system instead of trans main system was built in IHI KURE shipyard. As horizontal main ship is very rare for us, to recognize the accuracy of the calculation method, we carried out the ship board experiments under hydrostatic loaded condition. In the experiments, deflection of ships' hull and horizontal ring in addition to the stress distribution of trans ring and horizontal ring were measured. As regards structural analysis, two ways of analysis were studied as follows. (1) 3 dimensional frame analysis→3 dimensional F.E.M. calculation→2 dimensional F.E.M. zooming calculation. (2) 3 dimensional frame analysis→2 dimensional F.E.M. zooming calculation. As results of experiments and analysis, the followings were obtained. In case of (1) the results of analysis are in fairly good agreement with measured value. Also we recognized that the second method has enough accuracy for practical-design, although the accuracy of this method is inferior to the first method.
