In the present work, an impressed current cathodic protection (ICCP) system for the protection against corrosion of a 399-m-length container ship throughout its service life is designed. The study is carried out with the aid of a boundary element method code, accelerated by an adaptive cross approximation scheme, utilizing a detailed large-scale model. The exact geometry of the ship, the progressive damage of the coating system, and the dynamic state during the cruise of the ship are the main parameters taken into consideration in modelling. The main objective of the design process is to minimize the electric power, delivered by the ICCP system, determining the optimal number and location of the installed inert anodes to accomplish the absolute minimum protection potential on the immersed steel surfaces of the ship and, simultaneously, avoid overprotection. Performing an extensive parametric study, a six-zone ICCP system is proposed, consisting of 10 anodes at the hull and four identical anodes at each of four thrusters.

使用详细的BEM模型对集装箱船进行阴极保护

在目前的工作中，设计了一种外加电流阴极保护（ICCP）系统，以在399米长的集装箱船的整个使用寿命中提供防腐蚀保护。借助于边界元方法代码，利用详细的大规模模型，通过自适应交叉逼近方案加速了该研究。船舶的精确几何形状，涂层系统的渐进式损坏以及船舶航行期间的动态状态是建模时要考虑的主要参数。设计过程的主要目标是最大程度地减少由ICCP系统输送的电力，确定已安装惰性阳极的最佳数量和位置，以实现对船舶钢制沉浸表面的绝对最小保护，同时，避免过度保护。为了进行广泛的参数研究，提出了一种六区域ICCP系统，该系统由船体上的10个阳极和四个推进器中的每一个包含四个相同的阳极组成。
