     in last few decades increasing demand for energy lead to developing deep water technology for oil exploitation in severe ocean environment. an engineering idea is to minimize the structural resistance to environmental loads using compliant structures such as tlp and semi submersibles. however this structural flexibility causes nonlinearity in the structural stiffness because of large deformations. therefore the dynamic governing equations are complex to solve due to theses nonlinearities. semi submersibles have been dramatically improved in recent years due to their capability for deep water operation. waves and currents are important environmental phenomena affecting these offshore structures. estimation of platform movements in six degrees of freedom is vital in offshore structure design. in this research a detailed mooring analysis for a typical semi submersible was performed to make suere if the platform meets the necessary requirement in operational and survival conditions using romeo software.
