abstract
There is an increasing amount of laboratory and fieid data being gathered on the behavior of marine risers with the objective of developing a better understanding their dynamic behavior for design purposes. The focus of this discussion is the effective utilization of the reverse system identification technique for offshore applications and in particular the consideration of relevant practical considerations for its application to marine risers. Some of the critical issues include consideration of the importance the frequency dependence of key model parameters, the use of fully correlated data, the form of the nonlinear dependencies, and the need for a variety of input and response measurements.
