Cathodic protection is often used in offshore installations of wind turbines, drilling rigs and vessels, onshore installations including oil and gas storage tanks, and pipelines, and concrete installations usually of steel reinforcements. All these structures have metallic components exposed to corrosive environments (<a><span class=\"has-inline-color has-black-color\">see ISO9223).<\/span><\/a><\/p>\n\n\n\n<p>Mitigating corrosion is essential from both an operational and cost standpoint. Ignoring corrosion can shorten structure lifespan and increase maintenance costs leading to loss of critical material and increased human effort.

PITHIA-CP is based on the boundary element method (BEM), which reduces the dimensionality of the problem. It requires the discretization of the boundaries only in contrast with the FEM where the volume of the, e.g., sea or water, must be discretized.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PITHIA\u2019s unique BEM solver<\/h2>\n\n\n\n<p>But the method itself does not guarantee its efficiency. The critical turning point of PITHIA-CP lies in its solver, which is the only one to handle complex models with more than 1 million degrees of freedom (DoF) reducing the need for simplifications and modeling assumptions, allowing the confidence and accuracy of the computed results. Implementing innovative numerical techniques also offers drastically faster solution times while minimizing the computer hardware requirements.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Modeling environment and intuitive workflow<\/h2>\n\n\n\n<p>Through the partnership between FEAC and <a href=\"https:\/\/www.plm.automation.siemens.com\/global\/en\/\" target=\"_blank\" rel=\"noreferrer noopener\">Siemens<\/a>, engineers dealing with cathodic protection can now enjoy a modern, CAD-centric, highly efficient, multi-discipline modeling environment.
