The present invention is a method and an apparatus for reducing marine growth on an offshore oil platform member. The device uses a buoyant member coupled with a sleeve to scrape the exterior surface of the platform members. The buoyant component floats on the surface of the water and takes advantage of the ocean energy (i.e., the variation of the water's surface height due to the tidal and surge responses) to move the device up and down on the member. The liner and the buoyant member are adjusted for size and buoyancy to ensure that scraping occurs in the areas of the members that are most vulnerable to attachment of marine organisms.
