Abstract:The panel test on fouling organisms on five materials (epoxy board, HDPE, FRP, carbon steel and cement block) was carried out in offshore of Yantai Economic and Technological Development Zone(ETDZ) from May to July 2010.A total of 16 fouling organism species were recorded, among which Tubularia marina, Cryptosula pallasiana, Mytilus edulis and Hiatella orientalis were the dominant species. Among four pipe materials in seabed, cover area of the fouling organism on cement bricks was the largest, followed by FRP, HDPE, and carbon steel. The attachment of fouling organisms reached the peak from early July to mid-July. FRP or HDPE is recommended for water supply and drain pipe.
