MGPS or Marine Growth Prevention System on the ship helps to tackle the growth of marine organisms. Plus, it also helps to stop these organisms from getting deposited in the inner piping system of the ships as they are continuously supplied with water. Therefore, to prevent these marine organisms from damaging different parts of the ship, MGPS should be operating in the best condition. If you are someone who lives in Norway and wants to buy a ship for sale in Norway, we suggest you gain a good amount of information about ships. To help you understand MGPS, here we have discussed the same in detail.
What is Marine Growth Prevention System?
A marine growth prevention system that is also known as an antifouling system on a ship is a system that helps to eliminate the macro biofouling organisms that settle on the ship’s interior piping system. Thereby doing this, it helps to create less waste by increasing the pipes’ longevity. They also help to clear blockages that are caused by mussels and barnacles’ growth in the seawater cooling lines.
Three Types of Alloys Used for Anodes
The anode present in the marine growth prevention system helps by generating ions that get released in the seawater system and produce an anti-corrosive or anti-fouling layer on the heat exchanges, sea pipe’s internal sides and seawater system valves, AC units and refrigeration system etc. Now, three forms of alloys are used for the anodes.
Copper: Copper is one of the most used types of alloys that are used to eliminate marine fouling in strainers, piping, pumps and heat exchanger etc.
Ferrous: Ferrous alloys are used with anodes made of copper alloys and these work to eliminate corrosion in the CU/Ni pipework.
Aluminum: Aluminum alloys are also used with copper alloy anodes to eliminate corrosion in the ferrous piping system.
Now, let’s check out some of the tips that can help to maintain the MGPS. So, if you live in Norway and purchase a good ship for sale in Norway, you can use them to keep your ship’s internal piping system technically sound.
10 Tips for Marine Growth Prevention System to Operate Optimally
Now, let’s check out how you can ensure that the marine growth prevention system works optimally.
- You need to ensure that no aluminum parts or pipes are connected to the seawater system where the marine growth prevention system copper anodes are connected. This is because if in a copper-based anode, the aluminum is present it will cause a chemical reaction and the aluminum parts will get corroded.
- The current flow of the MGPS must be always maintained. Otherwise, a high flow of current will cause anode life to be short, while a low current flow will increase the life of the anode
- Note that when the MGPS is installed on the anode’s flanges, an isolation material must be provided to prevent any electrical connection between the non-ferrous surface and the anode.
- Always disconnect the anode’s supply when the strainer is opened for the purpose of inspection
- Do not use extra-long cables for the anodes of MGPS, as it can cause the terminal blocks to get overloaded
- To prevent the formation of air pockets inside the tank, open the air vent regularly for treatment tank-type MGPS
- If you open the anode, do not lift the anode by its cables
- If anodes of the MGPS are installed in a place where the blast cleaning or painting is not completed, it is important to ensure that these anodes must be protected.
- Renewed anodes must be placed in the vertical position unless it has been mentioned otherwise by the manufacturer or maker.
- If the value of the current in the anode is brought down to zero, then set the current to zero, this will ensure no current supply in the anode, and also anode will get renewed at the first chance. After you renew the anode, you need to reset the current to the settings it was at previously.
Conclusion
So, this is all you need to know about the marine growth prevention system on the ships, and more importantly how you can ensure that the system performs at its best capacity. These tips can help you to maintain the MGPS system in a ship. So, since you are considering buying a ship, make sure you install an MGPS system in it. Also, if you live in Norway, and want to buy the latest model ships for sale in Norway, you can consult a shipbroker.
