The offshore module fatigue analysis COMPUTE FATIGUE commands cannot be executed following an offshore module pile-structure interaction analysis. This essentially prevents the use of the jacket superstructure member forces computed by the pile-structure interaction analysis from being used in a subsequent fatigue analysis. There is no work-around for this problem.
