For the final design of moored floating structures, the design
regulations require a complete assessment of the damaged mooring
conditions. In this study, a twin hulled six column semi-submersible
has been modeled using Froude’s law of similitude with a scale of
1:100. In order to investigate the effects of single line failure of the
restraining system on the motion and the intact line responses, four seakeeping
tests have been conducted in head and beam random seas.
Results indicate that the platform migrates to new mean position with a
remarkable transient response directly following the line failure.
