Seismic Vulnerability Assesment of Jacket Type Offshore Platforms
Most of oil and gas offshore platforms are located in the seismic regains. So, Seismic vulnerability evaluation of the offshore platforms is one of the most important and vital issues in the structural systems. In this study, jacket type offshore platforms are studied by incorporating the pushover analyses and nonlinear time history analyses, in such a way that, first some push over analyses ar...
متن کاملMonitoring of Impacts of Offshore Platforms in the Adriatic Sea (Italy)
The oil and gas industry is truly global, with operations conducted in every corner of the world, since the worldwide increasing of energy demand has strongly raised the exploitation of non-renewable resources. The date of birth of the offshore industry is commonly regarded as 1947, when it was successfully completed by Kerr-McGee the first well in the Gulf of Mexico (Chakrabarti et al., 2005)....
متن کاملReliability Based Assessment of Existing Fixed Offshore Platforms Located in the Persian Gulf
This paper presents a detailed structural reliability procedure in order to achieve an acceptable safety margin for template type offshore platforms located in the Persian Gulf. Probability of failure in this study is calculated by considering the cumulative effects of all levels of wave loading during the lifetime of the structure and uncertainties associated with soil, material properties, co...
متن کاملSimple Pile-Soil Interaction Effect on Seismic Response of Fixed Offshore Platforms
In this paper effect of pile-soil consideration in obtaining seismic response offshore structure is assessed due to earthquake loading. InducedSeismic force is one of the most important excitations for the dynamic response of an offshore structure. According to API, Seismic forces should be accounted in platform design for seismically active regions in order to determine the allowable seismic r...
متن کاملSeismic Reliability Analysis of Offshore Fixed Platforms Using Incremental Dynamic Analysis
It is generally accepted that performance-based design has to be reliability-based. Seismic performance evaluation is based on nonlinear dynamics and reliability theory taking into account uncertainties during analysis. Considering the economic importance of jacket type offshore platforms, the present research aims to assess the seismic performance of offshore steel platforms. In this study, th...
