BIO-SHIELD sheathing will prevent biofouling on conductors, platform legs and diagonals, J-tubes, and risers… any piping or structure in the area of high buildup. In a typical application, Mark Tool Co. applies a 1/2″ thick layer of SplashTRON, bonded completely to the pipe; and a 1/16″ thick plate of 90-10 copper-nickel is bonded to the outside of the “SplashTRON” The alloy is completely insulated from any contact with the steel, and will retain its anti-fouling ability for the projected life of the installation. The first large scale application was on Shell”s EUREKA platform, installed in more than 700 feet of water off California. Sixty 24″ OD conductors were coated with BIO-SHIELD. Shell saved 250 tons of steel in the design because it did not have to allow for the effects of wave loading on conductors fouled with 24″ or more of marine growth. In addition, hundreds of thousands of dollars will be saved in maintenance expense over the life of the platform (projected to be 40 years) because the biofouling will not have to be removed regularly.
