From the sensitivity analysis of the interior jacket platform model respects to the variations of the physical parame-ters, the material and the geometry of the jacket structure as the correction parameter are researched,and the finite element model updating problem of the jacket structure is discussed .The objective function and constraint in optimization model have been established.The first-order optimization algorithm is adopted to optimize the correction parameter, from the optimization result, the iterative error is less than 1.35%.
