Hydro Electrique Marine (HEM), the specialists in desalinators and water treatment systems, are now part of the Cathelco Group. This electrical current, constantly monitored and regulated. 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. In the renewable energy market they have developed advanced ICCP systems to protect monopile, jacket and tripod offshore wind turbines. Impressed current cathodic protection systems are preferred by ship owners because they reduce fuel cost and maintenance. The offshore energy sector continues to gain in importance.Ĭathelco supply AF and ICCP systems for offshore platforms, semi-submersibles, FPSOs and FSOs. Cathelco Seafresh specialises in the production of reverse osmosis desalinators (watermakers) for yachts, commercial and naval vessels. Their product range includes marine pipework anti-fouling (also known as MGPS) systems and impressed current cathodic protection (ICCP) systems to safeguard the hulls of commercial and naval vessels against corrosion. In order to control the signatures and to preserve the integrity of a vessel, it is essential to be able to predict the impact of the design and operation of the Cathodic Protection system on the electric and magnetic fields.Cathelco are world leading designers and manufacturers of equipment for ships and offshore installations. For example, the relative position in the electrochemical table of steel and bronze provides a sufficient driving potential to create an electric field. They are caused by the galvanic potential differences between the metallic structures in contact with the sea water. It is important to note that UEP and CRM signatures exist even in the absence of a Cathodic Protection system. The corrosion related magnetic (CRM) field is the coupled magnetic field caused by the corrosion related electric currents flowing in the sea water between the SA and the ship hull. This is sometimes referred to as the Underwater Electrical Potential (UEP). The static electric signature is the electric field associated with the DC corrosion or cathodic protection current which flows through the sea water around a vessel. The design of a cathodic protection system is of great interest to defence organisations, not only to ensure the integrity of the vessel, but also because it contributes to the electric and magnetic signature of the vessel.Įlectro magnetic signatures are playing an important role in the detection of naval vessels and in the fusing of intelligent mines. With this scientific approach, the performance of a cathodic protection design can be tested and tuned to achieve the correct protection against corrosion desired on the structure. Consequently, the surfaces of the metal that suffer from corrosion or excessive protection against corrosion are disclosed and can be observed in 2D or 3D dimensions. The main objective of Cathodic Protection modeling is to demonstrate the actual performance of a Cathodic Protection system and adjust its design helping to reduce the final cost of the installation.Ĭomputer modelling is a mathematical tool in which the chemistry of the environment, the real properties of the materials and the actual electrochemical processes happening in the environment (i.e. Our engineers are specialized in Corrosion and Cathodic Protection and use a wide variety of software for this purpose to simulate a wide range of structures. E offer cathodic protection models for all types of structures and pipelines.
