ANTIFOULING + ANTICORROSION

EMCS Industries Ltd. has innovated antifouling and anticorrosion solutions since 1955. We pioneer solutions that reduce costs and improve marine assets’ operational and environmental performance—making us a trusted manufacturer and service provider 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 a vessel submerged in or exposed to seawater. Consequently, 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 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. 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 also impact operations, infrastructure, and vessel maintenance costs.

It is, therefore, a critical economic and environmental challenge for ship owners and operators and a further challenge to ensure healthy waterways and a flourishing economy.

INTERNAL CORROSION

A vessel’s internal sea chest, strainers, and piping systems are subject to corrosion due to seawater exposure. An ocean-going vessel relies heavily on seawater for cooling internal piping, condensers, generators, scrubber towers, and much more. This seawater uptake makes the vessel subject to corrosion of the internal piping systems.

EMCS manufactures MARELCO™, a suite of solutions, and distributes Cathelco products that protect 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 underwater steel or metal are subject to corrosion. For this to occur, the steel needs to be exposed to oxygen; water is a supply of oxygen. Therefore, all vessels built with steel hulls must fit with Impressed Current Cathodic Protection (ICCP)

Corrosion is also caused by an electrical exchange, especially between metals of different types. Metals comprise atoms, and metal contains an electrochemical charge since atoms have electrons. Corrosion occurs whenever two or more dissimilar metals are grounded. Steel hulls may be grounded by 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.
