Structural Responses of Offshore Jacket Platform Subject to Seismic Ground Acceleration and Wave Forces
Abstract: In this paper, the effect of seismic ground acceleration on offshore platforms in the Malaysian waters has been investigated. In the Malaysian region of South China Sea, the conventional practice applied to design of offshore structures is to assume that forces induced on the platforms due to waves, current and wind control the overall response of the structures. Seismic analysis is not conducted since Malaysia is not located in a …
