| Summary: | Marine growth is one of the main parameters to be considered for the design of fixed offshore platform; because it affects the wave and current force calculation, which is used for the design of sub structure. The thickness and type of marine growth depends on location, weather, the age of the structure and the maintenance regime. For Malaysian region, there is a guideline in PETRONAS Technical Standard, PTS, for marine growth thickness in the design. However, there is a recommendation to study on the updated real data measurement in order to redefine the marine growth thickness design standard. Therefore, the primary purpose of this research is to compare the current marine growth thickness in the PTS to the prediction thickness of real data measurement obtained from the three operational regions in Malaysia. Statistical method of extreme value analysis is used for this research in order to find the extreme value of marine growth thickness for every 5 m water depth interval. The result of the study have shown that there are quite differences between the values of the marine growth thickness in PTS to the prediction values of measured data. |
