Parametric Study for the Critical Tubular Joint of the Jacket Structure

The final year project titled 'Parametric Study for the Critical Tubular Joints of the
Jacket Structure' was carried out with the aim of studying the trends of the joint of the
submerged jacket structure accordingly to its conditions. To achieve the aim of the
project, several objectives been designed. Firstly is to study different load case of the
jacket and to determine the critical joint trends of the jacket when the jacket subjected
to several different loading conditions. Extensive literature review was conducted in
order to come up with ideas about the offshore structure, joint of the jacket structure,
environmental forces and the SACS program review, which the software been used to
run the analysis. The research been carried out for the five fixed jacket models with
various loading conditions, as all the data been input to the SACS program, analysis
been carried out on the jacket structure. The result of the joint can with the maximum
unity check been focused and been analyzed. The results then been presented in the
graphical form, which shows the relationship between depth of the critical joint and
total weight of the model; and depth of the critical joint and the water depth.
Environmental and the model weight were the significant elements that contribute to the
depth of the critical joint. From the graphical results presented the trends of the critical
joints been determined.
