ANTIFOULING and ANTICORROSION

EMCS Industries Ltd. is an innovator of antifouling and anticorrosion solutions since 1955. We pioneer cleantech solutions that reduce costs, improve performance, and protect the marine environment—making us a trusted manufacturer and service provider to over 147 vessels worldwide. You can count on our experience for marine growth protection and corrosion.

BIOFOULING

Biofouling is arguably the most significant challenge facing the commercial shipping industry and luxury leisure vessels. Additionally, it poses a considerable problem for the Blue Economy. 

Biofouling occurs when organisms attach and grow on parts of the vessel is submerged in or exposed to water. Consequently, resulting in sea life blockage of the sea suction, sea chests, fire suction, cross-over tanks, seawater piping systems, box coolers, heat exchangers, etc. Furthermore, it creates the potential to shut down critical systems. You will also find biofouling on the hull exterior responsible for decreasing a vessel’s speed and fuel efficiency while increasing emissions and maintenance costs.

Biofouling is also an open pathway for the introduction of cross-contamination of invasive marine species. Biosecurity is a concern as we advance. The spreading of marine species into and around new waters will harm fisheries, threaten healthy marine habitats, and have adverse health and economic effects. Biosecurity concerns are also impacting the cost of operations, infrastructure, and maintenance of a vessel. 

It is, therefore, a critical economic and environmental challenge for ship owners and operators. 

INTERNAL CORROSION

The internal sea chest, strainers, and piping systems of a vessel are also subject to corrosion due to their seawater exposure. An ocean going vessel relies heavily on seawater for cooling internal piping. In turn, this uptake makes the vessel subject to corrosion of the internal piping systems. The MARELCO™ suite of solutions protects against corrosion, increasing the ship’s efficiency, leading to longer life, less maintenance, and avoiding expensive overdesign.

EXTERNAL CORROSION

The hulls of large ships constructed of steel or metal which are underwater are subject to corrosion. For this to occur, the steel needs to is exposed to oxygen; water is a supply of oxygen. It is therefore imperative that all vessels built with steel hulls must fit with ICCP Anticorrosion System

Corrosion is also caused by an electrical exchange, especially between metals of different types. Metals comprise atoms, and since atoms have electrons, metal contains an electrochemical charge. Corrosion occurs whenever two or more dissimilar metals are grounded. Steel hulls may be grounded by physically touching or through a highly conductive solution such as saltwater, freshwater with high mineral content, or polluted freshwater. 

Corrosion protection provides a shaft grounding system that removes current produced by the ICCP anodes—preventing further corrosion of the propeller, shaft, and other critical parts of a ship’s propulsion system, internal seawater systems, and other niche areas.
