Abstract

The protection of steel construction, especially hull construction in sea water could be done by flowing its the steel construction, so that the surface potencial was decreasing. This down potential decreasing would be followed by decreasing of velocity steel corrosion. Thermodynamically, this condition would be imuned if the surface potential is on steel stability area. The electron supply through electrical conductor could be done by using by sacrificial anode and impressed current. The model developed in this paper was the analytical hierarchy process in which one method of its decison methods has complex. The model consist of four level, that are, 1) goal, 2) criteria, 3) sub criteria and 4) alternative. The result was that the decision making model selection of corrotion system protection on steel ship had several criteria and heterogen environment.
