MCPS Limited are one of a few UK manufacturers of sacrificial anodes, ICCP & MGPS but unlike other producers we also offer system design and provide full technical cathodic protection support, enabling our customers to reduce their costs. Our high level of experience ensures that MCPS fully understands and is able to supply corrosion protection equipment in accordance with the most stringent requirements as demanded by the Marine and Offshore Industry. In particular Port and Harbour owners to help combat against the phenomenon known as Accelerated Low Water Corrosion (ALWC) or Microbially Induced Corrosion (MIC).

Flush mounted (Hull) Anodes
Flush mounted or Hull Anodes are used to complement coated areas of a submerged structure or also to reduce the corrosion rates of a submerged bare metal area such as propellers. Alloys of Zinc, Aluminium and Magnesium with the necessary trace elements to provide correct performance are used for the manufacturing of sacrificial anodes. We offer a full range of Zinc, Aluminium and Magnesium Marine/Offshore anodes manufactured with Documentation to DIN EN 10204, 3.1B, containing full Chemical Analysis and Galvanostatic Testing according to DNV offshore standard RP B 401 (1993), NACE RP0387-99 & RP0176-2003.
Stand-off (Tank) Anodes
As with Hull Anodes, Tank anodes are used to combat corrosion. However it must be noted that hydrogen is evolved from Aluminium anodes and thermite sparking may occur when light alloys impact on rusty steel. Therefore there is a height restriction in cargo/ballast tanks in tankers that Aluminium anodes are not located at a height (in m) greater than 27/W where W is the total mass (in Kg) of the anode and insert. If in any doubt feel free to contact MCPS LTD for experienced advise.
Impressed Current Cathodic Protection (ICCP)
This type of Cathodic Protection relies on an external direct current source to be forced into the water from an inert non-wasting anode. Mixed Metal Oxide (MMO) anodes are in the electrolyte with the structure they intend to protect, and are made more positive than the structure by connecting the DC supply to both the anode and the structure (Cathode). A zinc reference cell controls the power unit DC output levels ensuring the correct level of cathodic protection. MCPS LTD provides Impressed Current Cathodic Protection (ICCP) systems and can carry out surveys and repairs all over the world.
Marine Growth Prevention Systems (MGPS)
Marine fouling and biofouling can form at all depths and temperatures and is commonly found in vessel's seawater cooling systems. A common method of fouling prevention is the Anti-fouling system or MGPS, which consists of two types of anodes, a Copper alloy rod to prevent fouling and Aluminium or Ferrous alloy rod to prevent corrosion. An anti-fouling anode once fitted requires little maintenance, prevent any marine plants, animals and bacterial growth settling in or around the sea chests/boxes and is not damaging to the environment. MCPS LTD offers new systems and replacement Anti-Fouling Copper Anodes.
Harbour / Jetty Anodes
Jetty piles corrode at rates far in excess of what is now acceptable due to an increase by the presence of colonies of bacteria caused primarily by Sulphur Reducing Bacteria (SRB). This phenomenon is known as Micro-Biologically Induced Corrosion (MIC) or sometimes known as Accelerated Low Water Corrosion (ALWC). Identified by orange soft organic bacteria (Ferric 3 oxides), with a black layer (Ferric Sulphide) hiding bright, pitted steel. Research revealed that Cathodic Protection greatly reduces the corrosion rate.
