Abstract:

In recognition of the significance of corrosion in its various manifestations to the life-cycle costs of naval ships, the Dockyard Laboratory of Defence Research Establishment Atlantic has embarked upon a multiphase study related to the development of boundary element analysis methods to support cathodic protection system studies. CPBEM, a PC based software suite that models both sacrificial and impressed current cathodic protection systems for surface ships, was developed. Several enhancements were made to CPBEM in current work to address several shortcomings identified during the recent application of CPBEM to modem frigates. Enhancements were made to the graphical user interface making it compliant with the Windows style of user interaction. Modelling capabilities were extended, through the use of a new improved meshing algorithm based on the quadrilateral paving methodology, to include an ability to describe anodes in close proximity to one another, and to describe the transom stem of the ship. Provisions for multiple polarization curves and paint damage areas were made. Other enhancements included the ability to compute the electric potentials and electrostatic fields at user specified locations in the fluid. A Tecplot interface was also supplied.
