Drag reduction of deepwater risers by the use of helical grooves

Model tests were carried out in a towing tank to investigate the effects of helical grooves on the drag loading of stationary circular cylinders in uniform and steady currents. A series of models were made and tested, including smooth and rough cylinders with and without grooves. The maximum Reynold...
