Today many complex models, typically finite element models, have been employed in the analysis of jacket offshore structures. However, these comprehensive models are not readily adopted in engineering practice, especially during the preliminary design stage. As the dynamic analysis of jacket platforms is very complicated, it will be very advantageous to make a simplified computational method to...

For structural reliability assessment or risk analysis of aging offshore steel structures, it is essential to have a probabilistic model, which contains specific statistical parameters, and predicts long term corrosion loss as a function of time. The aim of this study is to propose such model for offshore jacket platforms in the Persian Gulf. Field measurements for material loss due to uniform ...

In this research, the response of fixed offshore platforms equipped with shape memory alloy elements at the different depths under extreme wave loading are taken into account. For this purpose platforms located in different water depths 70, 110 and 150 has been considered. At first for evaluation of the nonlinear behavior of three platforms, pushover analysis using SACS has been engaged. Then n...
