The questions of recovering protective potential on underwater transitions of pipelines, in the presence of damages of insulating covering are considered. The way of ensuring security by means of laying of extended anode grounding in a conducting cover is considered. Use of a conducting cover with various specific electric resistance is offered. By results of mathematical modeling it is proved that application of a conducting pipe with various specific electric resistance allows to achieve more rational distribution of potentials with reduction of current of station of cathodic protection.
