Does anyone have information or ideas on how best to control internal biofouling on a carbon steel (CS) sea-water intake pipeline? The pipeline will be -12 miles (19 km) long with the intake at a depth of 500 ft (152 m). There will likely be no provisions for any type of chemical injection. Any ideas are appreciated, including changing of materials, coatings, etc. There are different solutions for your problem. Electro-chlorination is always a good solution--some seawater is passed through an electrolytic cell and converted in a solution of hypochlorite (CLO_3~(-)). There is no need for chemicals, there is excellent antifouling action, and no pollution problems. You only need a distribution system to carry the antifouling solution to the entrance of your pipe. That might not be possible for the length and depth you describe.
