ABSTRACT

However, quantitative data on the flow field around rough cylinders are relatively scarce, so the previous findings reported for the mean/RMS of

1 INTRODUCTION

Offshore structures which are exposed to the ocean currents became one of the main motivation in the Fluid-Structure Interaction (FSI) research studies. Design of these structures has been given growing attention due to the possible catastrophic effects in case of failure, especially in the areas where extreme environmental forces are likely to occur. In most cases, the structure is exposed to biofouling (also termed marine growth, marine fouling, or bio-colonization) that have several effects on the hydrodynamic loads. The uncertainties of biofouling effects are inherited from its random nature. These make it necessary to recalculated hydrodynamic forces under the new circumstances.
