ZBA-CATHODIC PROTECTION SERVICES is a privately owned company established in 1980 by mr Zymaris Vasilios. From date of inception to present the company has been involved in the manufacturing of sacrificial anodes ( Zinc, Aluminum, Magnesium ) for shipping offshore and industrial applications. Since the late 80's ZBA focused in providing innovating cathodic services in marine market.
The company's involvement in corrosion control spans all aspects of the marine sector including anodes for leisure boat market to commercial deep sea shipping and shoreline structures such as piling, jetties, lock and dock gates, pontoon systems.
For new buildings, the anodes come complete with cofferdam for either flange or welding installation, and a 6 mm2 flexible cable for connection in a nearby junction box. Replacement anodes are delivered with nuts and washers only.
Aluminium antifouling anodes complete with steel cofferdam. Al anodes interact together with copper anodes to supress corrosion and prevent marine fouling in sea chest and sea water intake systems with carbon and galvanised steel pipeworks. The anodes come in a variaty of dimensions.
The anode in the MGPS system generates ions that spread in the seawater system, producing an antifouling and anti-corrosive layer over the internal sides of sea pipes, heat exchanger (i.e. coolers and condensers), valves in seawater system, refrigeration systems, AC units etc.
Treatment tank setup with a spray nozzle in sea chest: In this system, a separate electrolysis tank with anodes is installed which sprays the ion through the nozzle in the sea chest. This system is installed on ships where sea chest or strainer mounting is not possible.
1. Ensure there is no aluminium pipes or parts attached to the seawater system in which MGPS copper anodes are connected. In a copper-based anode or MGPS systems, the aluminium will have a chemical reaction and act as an anode in the vicinity of copper, leading to severe corrosion of aluminium parts
2. The current settings for the MGPS should always be maintained as prescribed by the maker. A high current value setting will lead to a shorter anode life, and a lower current setting will increase the anode life
4. When the MGPS is installed on a non-ferrous metal surface (e.g. pipe upstand), the installation flanges of the anodes must be provided with an isolation material to ensure there is no electrical contact between the anode and non-ferrous surface, i.e. between two dissimilar metals
5. When the MGPS anode assembly is installed on the strainer (the anodes usually are installed on the strainer lid), it is essential to correctly place the anode inside the strainer basket in such a way that the anode surface does not touch any metallic components
6. Whenever the strainer is opened up for inspection or cleaning by lifting the lid, ensure to disconnect the supply of these anodes and not to damage them when removing the strainer basket lifting bar
10. If the anode current value is dropped to a low level, turn off the current knob to zero, i.e. no supply to the anode and renew the anode at the first chance. After renewing the anode, reset the current to the previously given current settings
14. The new spare anode which is of held-in type or flange sleeves type is supplied unpainted with a rust prevention coating. Ensure to remove this coating before the installation. Never use a wire brush or mechanical instrument to remove this layer. White spirits or turpentine can be used for the removal of this coating.
15. If anodes are installed in a space where blast cleaning or painting is not finished, they must be suitably protected. Before flooding the spaces, check to ensure that the protection has been removed. Also, remove any paint, tape adhesive residue or grease from the anode surfaces.
17. During dry docking for retrofit systems, before the vessel is launched or refloated, check the isolation of each anode from the hull, as well as continuity of the positive feed circuit to the anode
The MGPS installed on a ship must be effective against a large variety of organisms due to the multiple numbers and complex nature of fouling communities present in waters of different parts of the world the ship ply to.
Whenever two or more dissimilar metals are in electrical or physical contact, galvanic corrosion can take place. The process is similar to a simple DC cell in which the more active metal becomes the anode and corrodes, whereas the less active metal becomes the cathode and is protected.
In this method, we impress a direct current between an inert anode and the structure to be protected. Since electrons flow to the structure, it is protected from becoming the source of electrons (anode).The impressed current cathodic protection system usually provides electrodes of a much longer lifespan than a sacrificial anode.
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.
Our systems work by supplying a controlled amount of DC current to submerged surfaces using highly reliable mixed metal oxide anodes and zinc reference electrodes. This electrical current constantly monitored and regulated by the system itself to prevent the electrochemical action of galvanic corrosion before it begins.
The correct value of protection correct can be determined by the reference cell. It measures the voltage between the hull & seawater. These are either Zinc (Zn) or Silver (Ag) attached to the hull, but insulated from it, below the water line.
Each standard ICCP system utilizes a solid-state controller which monitors and controls the protection as measured by the Zinc Reference electrode. Anode current automatically increases when the electrode potential falls below the designated control value. An over- and an under-potential alarm is provided with the system package.
the piping and machinery system. The concentration of copper in the solution is less than 2 parts per million (PPM) but enough to prevent marine life from settling. The ALUMINUM anode produces ions which make noncorrosive layer ALUMINUM HYDROXIDE on pipeline system and prevent corrosion.
The ions, spread over the system and produce an antifouling and anti-corrosive film over the Sea Water Pipelines, Intercoolers, Condensers, Heat Exchangers, Valves, Refrigeration Systems, Box Coolers and AC units internally. Increasing seawater circulation and eliminating corrosion in the pipelines, increasing its duration and efficiency. That means energy savings

Marine growth refers to the accumulation of various marine organisms on submerged structures and surfaces. This buildup can include a variety of organisms such as barnacles, mussels, seaweeds, algae, and other biofouling species.
The Marine Growth Prevention System (MGPS), also known as the Impressed Current Anti-Fouling system, is a specialized solution designed to deter and tackle the buildup of marine organisms on submerged surfaces, particularly in ship seawater cooling systems and offshore installations.
An MGPS (Marine Growth Prevention System) anode is a specialized electrode used within the MGPS to prevent the accumulation of marine organisms on submerged surfaces, especially in ship seawater cooling systems and offshore installations. The anode, when subjected to electrolysis, releases certain ions into the surrounding water, which are unfriendly to marine life, thereby preventing biofouling.
MGPS anodes help prevent marine creatures from sticking to ships and underwater gear. They release copper ions that keep these organisms away. The benefits of using MGPS anodes go beyond just prevention, encompassing various aspects that can significantly enhance the longevity and efficiency of marine operations.
MGPS Anodes and ICCP Anodes are essential components in marine environments, each serving distinct roles in ensuring the longevity and efficiency of marine structures. While both are crucial for marine operations, they differ significantly in their primary purposes, working principles, applications, and environmental impacts. The table below provides a concise comparison of these two types of anodes:
MGPS Anodes play a crucial role in safeguarding various marine structures and systems from the pervasive issue of marine fouling. Their wide-ranging applications are a testament to their effectiveness and importance. Here are some key applications:
