| Abstract: | An experimental study was carried out in towing tank to determine the hydraulic drags of polypropylene mooring lines in order to investigate the drift resistances of the ropes in water.The coefficient of tangential drag was determined by two lines with different length,which is 0.036.The coefficient of normal resistance was got by towing a vertical line tied by steel block at the lower end,which is about 1.66. |
