A boundary element method for performing optimal cathodic protection
of a ship is proposed in this paper.
The method consists of three parts;
(1) a method for estimating the potential distribution on the hull from the
potential data at fixed several sensors, (2) a method for determining the
optimal currents to be impressed from each electrode, and (3) a method for
detecting the location of a paint defect from the potential change at the
An example problem is solved by a three dimensional boundary
element method to demonstrate the usefulness of the proposed method.
To prevent corrosion of a ship, the hull is painted and cathodic protection
is performed by impressing currents from several electrodes.
for monitoring potentials are located at several points ...
