A jacket structure installed on the seabed will experience external loading mainly from the environment. Current-structure interaction is known to directly contribute in the increment of total environmental load. In addition, current profile as well as the magnitude of it velocity may affects it final contribution of external loading on the structure. In this paper, the effects of current parameter and profile on loading of off shore jacket structure is investigated. Details studies focused on current velocity, wave-current interaction and current profiles affecting the magnitude of base shear and overturning moment on a typical shallow water jacket structure. In this study, the result shows there is significant effect of current velocity on the loading of drag dominated structure.
