What is the CAPAC® System?
The CAPAC system is a long-term solution for preventing electrolysis and galvanic corrosion from attacking the submerged surfaces of vessels and mobile offshore production and drilling platforms. This permanent, on-board, or on-site automatic system consists of anodes, reference electrodes, shaft grounds and power supply/controllers to maintain just the right amount of protection.
Why install a CAPAC system?
Our CAPAC ICCP (Impressed Current Cathodic Protection) system is designed for a 20 plus year service life and is recognized as a superior alternative to sacrificial anode systems, which require frequent replacement.
The CAPAC system automatically provides optimum levels or current to ensure corrosion prevention, while also protecting the coating and its surface.
How does an ICCP System compare to a Sacrificial Anode System?
ICCP System | Sacrificial Anode System |
Long Life (20+ year design) | Limited life |
Extending drydocking interval (5 years or more) | One to Two year drydocking interval |
Optimum Protection | High stress on new coatings / increased wear on older coatings |
Help reduce fuel consumption by maintaining a smooth hull | High drag and fuel use |
Real time monitored levels of protection | Unknown protection levels |
What is the Chloropac® system?
Chloropac is a Marine Growth Prevention System (MGPS) that produces sodium hypochlorite for direct injection into a vessel's sea chest and sea water cooling system. This unique technology is self-cleaning so does not require costly acid washing – leaving you to run your platform, vessel or plant, and not worry about biofouling issues.
Why use a Chloropac system?
Chloropac Systems provide the most effective, environmentally safe method of preventing biological fouling, using technically superior equipment for energy-efficient, long-term operation.
How does the Chloropac system compare to other technologies?
Chloropac System | Other Technologies |
No hazardous chemicals required | Long-term storage of bulk sodium hypochlorite |
Continuous treatment of micro and macro fouling | Sacrificial anode MGPS systems need to be replaced frequently at a high cost to the ship owner |
Utilizes cell technology with a large surface area for increased output per cell - up to 6x more | Takes up a larger footprint where space is a premium |
Self-cleaning technology ensures continuous and reliable operation | Flat Plate type cells require periodic acid cleaning to prevent clogging |
