Numerical and Model Test Results for Truss Spar Platform

A truss spar model was tested using regular waves in a wave basin and the responses in surge, heave and pitch were measured. A MATLAB program named ‘TRSPAR’ was developed to determine the responses by numerical method. This program was run using the model parameters and it gave results which agreed well with the corresponding results obtained from the test measurements. This program was then applied to a prototype spar, named Marlin truss spar. The simulated results were compared with the corresponding numerical
results and test measurements.
