Abstract Offshore platforms in seismically active areas must be designed to survive in the face of intense earthquakes without a global structural collapse. The structural design requirements of an offshore platform subjected to seismic induced forces in the jacket can play a major role in the design of the pile-founded offshore structures constructed in seismically active regions. The present study attempts to estimate the dynamic earthquake response assessment as well as, in-place behavior assessment of a typical pile-founded offshore platform situated in the entrance of the Gulf of Suez region. A finite element model by structural analysis computer system (SACS) have been used to simulate 3D typical jacket type offshore platform taking into consideration the effect of structure-soil-interaction. Soil properties at the site were manipulated to generate the pile lateral soil properties in the form of load deflection curves, based on API-RP2A (American petroleum institute) recommendations. |
