Experimental verification of a semi-submersible platform with truncated mooring system based on static and damping equivalence

ABSTRACT

Physical model experiments of floating facilities in deep and ultra-deepwater with full-depth mooring system present obstacles because no wave basin is sufficiently large to perform model testing in reasonable scale. Truncation of full-depth mooring system is required for model test. Based on both statics and mooring-induced damping equivalence, truncated mooring lines are designed. A model test of a semi-submersible platform with full-depth and truncated mooring system is presented in this paper. In general, good agreements between the motion responses of semi-submersible platform with full-depth and truncated mooring system are found based on the model test results.
