Applications

Our systems are designed for sectors such as:

  • MARITIME (military & civil vessels)
  • OFFSHORE RENEWABLE
  • OIL & GAS
  • ONSHORE
  • REFINERIES
  • FACILITY PORTS
  • RETROFIT PROJECTS

The power output ranges that we can manufacture range from 50A to 600A, depending on the application required. Other powers and configurations, consult.

The input voltage for our CPUs is 220-440Vac / 3pH / 50-60Hz and we can configure the outputs to 12 or 24Vdc as required and with a ripple content of less than 0.1% in 6 nominal loads OR333.

ICCP

We use a single control card for two anodes and each card can receive the potential signal of up to two reference electrodes per anode, allowing to obtain a more optimized anode output of each anode. In addition, the cards can receive potential signals from the propeller, rudder, appendices and have an interface for remote communications on board and satellite.

CPU or Control Panel

WWI has made a major advance in ICCP technology with the development of CPU Aquamatic® VI, the intelligent system for naval vessels. Warships require specialised ICCP systems which prevent hull corrosion, but do not interfere with the electrical war-fighting capability of the ship.

With the power modules the network voltage is rectified and a continuous voltage of 300Vdc is obtained at the input of the module. Through an internal high frequency transformer the input voltage of 300Vdc is converted to an output voltage of 12Vdc or 24Vdc as required.

 As the size of the transformer is inversely proportional to the working frequency for the same power, the weight and the volume can be reduced considerably while obtaining curling voltages considerably lower than those of a system with thyristors.

The CPU Aquamatic® VI system is specifically designed to meet the stringent requirements of EMC/EFI, shock, vibration, low maintenance and flexibility of operation in the military environment.

Impressed Current Anodes

WWI has several types and capacities of anodes, depending on the applications required. Circular, elliptical and linear and with capacities ranging from 25A to 300A. Other capacities, consult.

Comprise a Ti-MMO, Pb-Ag, Pt-MMO carrier plate, encapsulated in a glass reinforced resin holder. The anodes are supplied completes with their full cofferdams, cable glands, hull penetration box, metallic plates and dielectric shield material, if required.

The anodes can be changed with the vessel afloat by diver.


Reference Electrodes

Reference electrodes can be it recessed or surface which comprise a block of high purity zinc (SHG 99.995%) that because of its robust construction and stable electrochemical characteristics is an ideal material for reference purposes.

These are supplied together with their neoprene and teflon sleeves, hull penetration boxes and full cofferdams, if required.

Depending on customer requirements, referenced or surface reference electrodes can be manufactured.


Shaft Earthing System

The propulsion shaft earthing system is carried out by friction brushes of very high conductivity, facilitating the return of the current to the hull by closing the circuit. Our brushes are silver - graphite placed on double brush holders. The contact between the brushes and the shaft is made by means of a slip ring which has a high conductivity copper band inserted.

Also and if the client requires it, a third brush is installed that makes the monitoring function that connects to the CPU.
