Nonlinear Coupled Dynamic Response of a Semi-submersible Platform

The dynamic behavior of a conventional semi-submersible was investigated both numerically and experimentally in regular and irregular waves. In the mathematical model, the dynamic equilibrium equationswere developed and solved in time domain using a common reference axis system fixed on the mean...
