Abstract ID#:
A105

 

Report Title:
Evaluation of the Dynamic Response of Spar Platforms

 

Authors:
Iftekhar Amam, Texas A&M University

 

Report Date:
February, 2000

 

This work compares different analytical and numerical methods to evaluate the dynamic response of Spar platforms due to unidirectional and multidirectional waves, current and wind. Various analytical models of wave kinematics and hydrodynamic forces as well as different methods of numerical analysis are compared. Of particular interest are the second order difference frequency forces and structural responses. Some numerical predictions in time domain using Morison’s equation and second order diffraction theory are compared to measured lab and field data. The statistical nature of the response is also studied.
