SHIP HULL ANTI-FOULING SYSTEM UTILIZING ELECTROLYZED SEA WATER

Mitsubishi Heavy Industries, Ltd., has recently developed a new anti-fouling system for protection of ships' hulls. In this system, electrolyzed sea water is mixed with air and released from nozzle pipes which are fitted to the bilge parts of a ship's hull, so that the mixture of electrolyzed sea water and air rises up to the water surface along the ship's side shells. A test unit with a capacity large enough to cover a 100 m long ship's shell plate was built and operated continuously for five months producing and issuing the electrolyzed sea water over a 4 m times 10 m steel plate immersed in sea water for confirmation of its efficiency and durability. On the basis of the above test results and the preliminary designs of the system worked out for several different ship applications, it is confidently believed that the system offers a great benefit to shipowners.
