| Abstract: | Aiming at the issue of deformation control during superstructure integral hoisting of large ships , the MSC.Nastran software is utilized to carry out the FE analysis for a large VLCC′s superstructure .According to the characteristics of the re-sponse , a reasonable and effective method of structure reinforcement is put forward , by which the response of stress and displace-ment during the hoisting goes down to a safe level . |
