Designer Wave Load for Approximation in Extreme Response of Offshore Structures

摘要

To standardize and simplify the design process of offshore structures, the designer wave load is developed. The load can accurately predict the extreme response of offshore structures by the static analysis under the realistic wave conditions. The designer wave load can be calculated by multiplying modification factors and the wave force based on Morrison's equation with the mean wave height and mean wave period. For designer's convenience, the modification factors are graphed as a function of the wave height, wave period, sea depth and natural period of offshore structures. The analytical accuracy of the proposed method is also examined.
