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 …

INVESTIGATIONS ON BIODIESEL FROM WASTE COOKING OIL AS DIESEL FUEL SUBSTITUTE
Abstract: The waste cooking oil (WCO) as alternative fuel for diesel engines is the aim of this investigation. The high viscosity and poor volatility are the major limitations of waste cooking oil for their utilization in diesel engine. The most convenient method to use waste cooking oil as fuel is to convert it into biodiesel through transesterfication. The properties of waste cooking oil methyl ester such as viscosity, specific gravity, calorific …
