Abstract: This paper describes a software package (OTRC-Riser-91) that was developed under the sponsorship of the Offshore Research Technology Center that is funded by the National Science Foundation and administered by the University of Texas at Austin and Texas A&M University. The software package was especially conceived for educational or research purposes with emphasis on user interfaces, automatic data generation and graphical display. This approach would replace the cumbersome and time consuming data preparation and lengthy output that are normally found in commercial or research programs. As a result, a state-of-the-art workstation approach has been developed that incorporates sound analysis procedures for deep water risers. The software package is easy to use - yet it is capable of producing real time graphical simulation of the structural response of risers in deep water. A companion project is now underway that will incorporate this formulation for a complete coupling of the tendon/riser and hull for the analysis of tension leg platforms.
