Wind-Tunnel Tests on a Model of a Semisubmersible Platform and Comparison of the Results With Full-Scale Data

This paper presents an analysis of a model investigation on a semi-submersible platform in a wind tunnel. Both forces and overturning moments on the part above water and the part below water are investigated. Furthermore full-scale anchorline force observations as reported earlier are re-analysed and the results are compared to those of theoretical calculations and of the model tests. Paper presented at the 14th annual Offshore Technology Conference, Houston, USA, May 3-6, 1982.
