Seismic 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...
متن کاملStructural System Reliability Framework For Fixed Offshore Platforms
The main objective of this project is to develop a generic framework which will set the basis for achieving more consistent system reliability assessments. The main steps involved in a system reliability assessment, together with the key technical and philosophical issues, will be identified and examined. Their interrelations and relative significance will be assessed in order to link them toge...
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 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 کاملReliability Analysis of Tubular Joints of Offshore Platforms in Malaysia
The oil and gas industry has moved towards Load and Resistance Factor Design through API RP2A LRFD and the recently published international standard, ISO-19902, for design of fixed steel offshore structures. The ISO 19902 is intended to provide a harmonized design practice that offers a balanced structural fitness for the purpose, economy and safety. As part of an ongoing work, the reliability ...
