Cathodic Marine Engineering Pte Ltd. products

Cathodic protection (CP) is a method of corrosion control that can be applied to buried and submerged metallic structures.

Impressed current cathodic protection systems are the ultimate state-of-the-art, long-term solution to corrosion problems, and are recognized as a superior alternative to sacrificial anode systems, which require frequent replacement. Impressed current cathodic protection systems are preferred by ship owners because they reduce fuel cost and maintenance.

In cathodic protection, pieces of metal (known as Sacrificial Anode) are linked electrically to the ship’s hull. These anodes, are made of metals more reactive than the material used for the ship’s body and systems. As such, they will corrode in place of the ship’s body and systems while the ship stays protected, giving rise to the name ‘Sacrificial Anodes’.

Ships are dependent on the seawater upon which they travel for a variety of reasons. One primarily function seawater serves is to cool the engine and parts of the ship while it’s operating. The used seawater is then discharge back into the sea and new seawater taken in, forming a continuous flow of exchange of saline water between the ship and its surrounding aqueous environment. Despite its benefits, the downside of this is that seawater contains marine organisms (both macro and micro), some visible to the naked eye while most are not. As the seawater passes through the various pipes and parts of the ship’s engine, marine organisms are deposited along their surface. Over time, the deposit builds up, reducing the efficiency of the ship’s engine and in severe cases, choking the entire system of the ship’s engine which could eventually lead to malfunction of the entire ship’s engine.

Using the latest advancement in marine research and technology, the Electrochlorination / Hypochlorite System was designed to impede the adhesion of marine growth to the ship’s internal through the release of chlorine into the water taken by the ship to cool its internal systems. Using electrolysis, this intelligent, self-sufficient system is able to produce chlorine by breaking up the water molecule present in seawater itself, keeping your ship in peak condition always.
