| Abstract: | The FEA software MSC. Patran and MSC. Nastran were applied to calculate directly the structural strength of the 500 t floating crane which was renovated design from a barge. The whole hull structure was FE modeled. Various loadings acting upon the ship were calculated rationally. After adjusting the balance of loadings on the ship, the function of inertia relief was used to calculate the structural strength directly of the free floating crane. The numerical results can be used to the renovation design and optimal design of the ship structure. |
