There has been an increased need for understanding of how ship’s cathodic protection systems work in shallow water environment. This is a result of the evolving role of the US Navy. The existing cathodic protection system design process relies on experimental processes. This paper investigates a proposed modification to a deep water experimental facility to allow for measurements of electrical fields, a pertinent design measurement, in shallow water conditions. The modifications involve the insertion of a false bottom in the existing deep water tank. The work presented here are a series of computational studies that establish that the insertion of a false bottom would provide an electric field environment that is equivalent to shallow water for the depths considered.
