Sažetak

Physical model tests of floater with full-depth mooring system present obstacles because no tank is sufficiently large to perform model testing in reasonable scale. This paper presents numerical simulation on design method of equivalent truncated mooring systems for model testing of offshore platforms in wave basin. Based on static and dynamic equivalent, two approaches are used to design the truncated mooring systems, respectively. Considering a semi-submersible platform with full-depth and corresponding two equivalent truncated mooring systems, the floater responses and mooring line tensions are compared. The feasibility of model test with equivalent truncated mooring systems is discussed.
