A computer aided design approach for deep water tension leg platforms
- Univ. of Texas, Austin, TX (United States). Dept. of Civil Engineering
In this research, a software package was developed under the sponsorship of the Offshore Technology Research Center that is funded by the National Science Foundation and administered by The University of Texas at Austin and Texas A and M University. This software package (Johnson (1993)) was especially conceived for educational or research purposes with emphasis on user interfaces, automatic data generation and graphical display. As a result, a state-of-the-art workstation approach was developed that incorporates sound analysis procedures for deep water Tension Leg Platforms (TLPs). The TLP program (OTRC-TLP-2D93) is easy to use -- yet it is capable of producing real time graphical simulation of the structural response of TLPs in deep water. Several options are available for treating structural nonlinearities as well as nonlinearities in the forcing function based on Morison`s equation. The formulation is based on a two-dimensional model and accounts for a fully coupled analysis of the hull and tendons. The software is designed to handle wave, wind and deep currents with a rich set of user selectable options. General considerations for the software package and the underlying theory are presented. Numerical examples for a TLP subjected to wave, wind and current at an ocean depth of 5,000 feet are presented showing how the problem can be analyzed in a user friendly environment, complimented by the graphical interface developed.
