What is Cathelco anodes?

Cathelco has developed a range of anodes with mountings which enable them to be installed in the seachests or strainers of almost any type of vessel. The size of the anodes is determined by the flow rates and their anticipated design life, taking into consideration the scheduled dry docking period.

What is Cathelco system?

Our Cathelco marine growth prevention systems (MGPSs), also known as antifouling systems) usually consist of pairs of copper and aluminum anodes, mounted in sea chests or strainers and connected to a control panel.

How can we stop marine growth?

Check out these four key ways you can prevent marine growth on your boat’s hull.

1. Bottom Painting With Anti-Fouling Paint. A boat’s hull needs to have a layer of protection to stop marine growth from sticking onto its surfaces.
2. Invest In An Marine Growth Prevention System.
3. Regular Bottom Cleaning Sessions.

What is marine growth protection system?

The Marine Growth Prevention System (MGPS) has been developed for ships with the sole purpose of tackling marine organism growth, preventing it from depositing on the ship’s interior piping systems, which are continuously supplied with sea water.

What are sacrificial anodes made of?

Sacrificial anodes generally come in three metals: magnesium, aluminum, and zinc. Magnesium has the most negative electropotential of the three (see galvanic series, right) and is more suitable for on-shore pipelines where the electrolyte (soil or water) resistivity is higher.

How do I get barnacles off my propeller?

I recommend spraying them with Algex and then wrapping the prop in a plastic bag to prevent evaporation while the chemical does its work. Let them sit in the plastic for 30 to 60 minutes. It will soften the barnacle shells so that you can knock them off with a plastic or wooden scraper.

Should I paint my boat prop?

Seidel says, “The more you use your boat, the less likely [your props] will collect shells. If you use it every week and scrape your props occasionally it may stay clean on its own. But if your boat sits unused more than ten days at a time, you’re going to need prop paint.”

What causes biofouling?

In most cases, biofouling is caused by heterotrophic organisms; and thus, micro- organisms convert dissolved organic material into bio- mass locally. This is the same mechanism which sup- ports biofilm technology – biofouling can be considered as a biofilm reactor in the wrong place at the wrong time.

What problem does marine growth have on vessels?

Marine growth such as barnacles and mussels have been the reason for problems such as decreased ship efficiency, corrosion etc. Biofouling not only sticks to the external surface of the ships but also gets into the water intakes and sticks to the surface of the pipes leading to problems such as blockage and corrosion.

Does anode corrode in ICCP?

Impressed current cathodic protection (ICCP) In contrast to GACP, the cathodic protection current is supplied by the DC power source and not by corrosion of the anode itself.

Can the cathelco anodes be installed in a treatment tank?

In special cases where the Cathelco system is installed to supersede existing chemical-based antifouling equipment, the anodes can be mounted in treatment (electrolysis) tanks in order to reduce installation costs by utilizing existing pipework.

What is a cathelco system?

The Cathelco system is based on the electrolytic principle and consists of a transformer/rectifier which feeds an electrical current to copper and aluminium anodes. In operation the anodes produce ions which are carried throughout the pipework system creating an environment in which barnacles and mussels cannot settle or breed.

Where can Pico anodes be used?

Their compact design means they can be used in a wide range of applications. As the smallest in the Cathelco range, Pico anodes can be fitted in 3” diameter pipes on yachts and workboats. They provide a ‘trace’ of copper which is sufficient to prevent bio-fouling in small pipework systems.

What is cathelco anti-fouling system?

Cathelco anti-fouling system. The anti-fouling system based on the electrolytic principle. It consists of copper and aluminium anodes which are fed with an impressed electrical current from a control panel. The anodes are usually mounted in pairs in the ship sea chest or strainer where they are in direct contact with the flow…
