WHAT IS MGPS?
Bio-fouling - the problem
The dark and warm environment inside ship's pipework provides a hospitable environment for marine organisms such as barnacles, encrusting bryozoans, molluscs and mussels. These settle on the internal surfaces of ship's sea water pipes causing blockages and reduced flow. This leads to reduced cooling efficiency, higher fuel consumption and can affect the safe operation of the vessel.
MGPS - the solution
Marine Growth Prevention Systems (MGPS), also called Impressed Current Anti-Fouling (ICAF) or Anti-Fouling & Corrosion Control (AFCC) systems are installed in ship's sea water inlets (either in the seachest or in the strainers) to prevent marine organisms from settling in the sea water pipes.
BENEFITS OF MGPS/ICAF
01
Prevents Clogging and Damage to Cooling Systems
Ships rely on seawater cooling systems to maintain optimal engine and equipment temperatures. Without an MGPS, marine organisms like barnacles and mussels can grow inside pipes, leading to blockages that reduce cooling efficiency. Over time, these blockages can cause overheating, equipment failure, and increased maintenance costs.
02
Reduces the Need for Manual Cleaning and Costly Dry-Docking
Regular cleaning of fouled pipes requires dry-docking or labor-intensive maintenance, which is expensive and time-consuming. MGPS continuously prevents biofouling, reducing the need for frequent cleaning and ensuring smooth operations.
03
Maintains Optimal Operating Conditions for Ship Engines and Auxiliary Systems
A clean seawater cooling system ensures that engines, heat exchangers, and auxiliary machinery operate at peak efficiency. By preventing biofouling, MGPS helps maintain stable temperatures, reduces fuel consumption, and prolongs the lifespan of critical components, ultimately improving a ship’s overall performance and reliability.
PRODUCT OVERVIEW
01
Control Panel
Compact and reliable, Typically, they are IP 44 rated and can be built to higher standards as required. Provides a constant current to the anodes.
02
Mono Anodes
Single element anodes - copper, aluminium and cast iron. For installation in seachest or strainers.
03
Combi Anodes
Dual elements on a single mounting. These are typically used where space is limited. Can be either CU & AL or CU & FE.
04
Box Cooler Anodes
Fully submersible anodes, fitted under box coolers for effective anti-fouling.
05
Flanged Mounting Sleeve
Mounting Sleeves are required to install the anodes on the seachests or strainers. Flanged mounting sleeves are made from Mild Steel.
06
Nylon Mounting Sleeve
Mild Steel mounting sleeve can be welded directly to the seachest top plate or strainer cover.
FAQs
Electrolytic MGPS: Uses copper and aluminum or iron anodes to release ions into seawater.
Yes, MGPS can be retrofitted onto existing vessels. The installation process involves fitting anodes into seachests or cooling water intakes and integrating a control panel for monitoring and adjustments.
MGPS anodes are typically installed in seachests or seawater intake systems, where they release ions into the water before it enters cooling circuits.
Anode lifespan depends on usage and ship operating conditions, but typically ranges from 1 to 5 years.
MGPS requires minimal maintenance. Periodic checks ensure proper ion release, and anodes may need replacement based on wear. The control panel should also be monitored to verify system performance.
MGPS releases controlled amounts of copper and other ions, well within environmental limits, making it a safer alternative to harsh chemical treatments.
MGPS significantly reduces marine growth but may not eliminate all fouling. Regular inspections and complementary measures like antifouling coatings can enhance protection.
Yes, MGPS is effective for offshore platforms, seawater intake systems, and other marine infrastructure prone to biofouling.
Unlike manual cleaning or chemical dosing, MGPS provides continuous, automated protection with minimal maintenance and environmental impact. It helps reduce operational costs and improves long-term efficiency.
MGPS works in most seawater conditions, but efficiency can vary based on salinity, temperature, and flow rate. Systems can be adjusted to optimize performance in different environments
