Aiming at the problem of over-deformation occurred in the final assembly process on the slipway for half stereo subsection of the engine room of 76 000 t bulk carrier EZ31P(EG31P+EG32P),this paper calculates the stress and deformation in the actual support condition by using the finite element numerical simulation. The results are consistent with the field measurement. It controls the elastic deformation of each section by improving the support solutions in the final assembly process ,and applies the solutions to the on-site assembly. The deformation of each section is measured within the permitting range of accuracy,which has settled the final rapid assembly process.
