Tension Leg Platform (TLP) is a well-known vertically moored structure for oil exploration. Because of inherent nonlinearities of the structure and environmental loads, the dynamic response analysis of the structure is very complicate and for the design process of a TLP, extensive spectra of responses and different structural and environmental conditions are necessary to be investigated. Minimizing of down time is an important problem in optimum using and functionality of offshore structures. This paper deals with the optimization of geometrical parameters of TLP regarding to minimize the down time period. Here the most effective parameter is the vertical acceleration. The regular wave loads on the elements of the pontoon are calculated using Airy wave theory and Morison equation, ignoring the diffraction and radiation effects. The nonlinear equation of motion is solved in time domain using modified Euler method (MEM). Finally by using Genetic Algorithm method, the optimized geometrical configuration for the TLP is determined. Numerical results show the effectiveness of obtained configuration of elements on minimizing down time.
