A study was undertaken to obtain design data for possible damage scenarios for a planned deep-sea power cable between two Hawaiian islands. The combined results of abrasion and corrosion-erosion of cold-drawn 0.85 % C-steel armor wire in seawater against seabottom rocks indicate the failure of the proposed design in the desired design life due to these mechanisms is of only intermediate probability. The results also have some general applicability to abrasive wear by and of natural media. The steel and the rock wear simultaneously, with the rock wearing about 150 times faster than the steel. The results can be explained by considering the armor wire as a hard tool causing wear of the rock while abrasion of the steel is caused solely by the hard marine olivine grains which constitute 6 percent of the rock. Both adjusted wear rates are comparable to laboratory data on abrasion by hard abrasives.
