Overview

The Farwest Corrosion Marine Growth Prevention System (MGPS) prevents marine growth from accumulating. It is ideal for use in marine seawater cooling systems to keep the piping clear of biofouling.

Marine growth results from the settlement of larvae and subsequent marine life forms, in particular hard shells such as acorn barnacles and gooseneck barnacles. In extreme cases, marine growth fouling can become so serious as to completely obstruct the flow of seawater through cooling piping. Lesser cooling system complications include overheating, reduced efficiency, increased corrosion, and loss of vessel speed -- a serious situation since most vessels demand maximum speed.

The MGPS Marine Growth Prevention System is electrolytic in action. Copper, aluminum or iron anodes are typically installed in vessel sea chests. These anodes are powered by a low voltage DC power supply, which provides a source of regulated DC current to the anodes. The resulting release of copper ions from the copper anodes is sufficient to deter the settlement of larvae within the piping. This release of copper ions is extremely small and is measured in micrograms per liter of seawater.

Advantages

• Simple Installation
• Automatic operation
• Minimum required supervision
• Complete protection against fouling
• Reduced corrosion
• Minimal power requirements
• Easily adapted to specific vessels:
  1. Quantity of seawater to be treated (flow rate) measured in cubic meters per hour.
  2. Required life of the anodes. This is usually determined by dry docking intervals for sea chest mounted anodes.
  3. Type of materials used in the sea water piping system.

 
Anode Sizes & Types

Anode diameter and length determine the DC current output of the anodes and ultimate life span of the MGPS system. The tables below show standard anode meterials,diameters and lengths. Custom lengths can easily be supplied.
