Abstract

This report describes an analysis ofKikeh Truss Spar subjected a regular wave loading. Many innovative floating offshore structures have been constructed over the world nowadays. This is because shallow water hydrocarbon reserves continue to reduce while global demand increases. One such type of floating offshore structures is the Spar platform. Recently, the first Malaysia deepwater platform was installed which is Kikeh Truss Spar. A Study on this Kikeh Spar Platform was conducted to analyze its dynamic behavior when subjected to regular waves. Generally, the spar platform is described as a rigid body with six degree of freedom at the Center of Gravity (COG). A unidirectional regular wave is used for computing the incident wave kinematics by Airy's wave theory and excitation forces by Morison equation. Severe storm wave was predicted using the P-M model. The response analysis was conducted in frequency domain approach without any iteration by using Response-Amplitude Operator as transfer function. It is important to analyze the motion response of spar in order to ensure its stability even during extreme wave condition. Parametric study was also conducted to observe the response behavior with changing parameters. The results obtained from the analysis are presented using graphs and tables. Key words: Regular wave, Kikeh Truss Spar, dynamic analysis, frequency domain, parametric study
