During the commissioning of Bipole II electrodes, important performance aspects were brought to light, in addition to those reported previously, after the measurements made during Bipole I commissioning. The following aspects are treated in the paper: the mutual influence between two neighboring electrodes was examined, leading to a simple methodology for the measurement of the grounding resistance of one of them, provided the other's resistance is known; Electrode I curves were remeasured after 2 1/2 years, and the changes in these curves quantified; measurements in more favorable conditions in an irrigation system were analyzed, leading to a change in the touch potential calculation method previously adopted; and the allowable voltage limits for immersed body situations were reviewed leading to appropriate mitigation criteria for a floating dredge installation.
