Abstract
Since cathodic protection (CP) systems were first applied, engineers have used
experience and intensive monitoring to optimise their design to prevent
corrosion. The use of sacrificial and impressed anodes on shlp's hull, offshore
structures and pipelines has become standard practice in order to preserve the
structure and to protect coatings. However, the correct position and current of the
anodes is a subject, which has been recently studied by the scientific community,
since its adequacy is of vital importance to the performance of the CP system as
a whole. Incorrect currents and positions would lead to unprotected or
overprotected areas.
Optimisation methods combined with the Boundary Elements Technology
have become a useful technique to analyse this situation. Up to now, studies have
been carried out using few anodes to optirnise their current
