The present of marine growth attached on any submerged section of offshore installation will significantly affects the loading magnitude and its related response. Basic consideration must be given at earlier stage of design process of this structure so that the appropriate design allowance be introduced in the structure’s final dimensions. This paper investigates the effects of marine growth presence on structural response in particular the base shear and it associated overturning moment. Base shear was increased by more than 130 percent as compared to newly installed structure. Overturning moment was increased by about 110 percent due to increases in marine growth on the submerged section of the structure.
