ABSTRACT:
A method is provided for preventing biofouling on the surface of structures, such as docks, ships, oil drilling platforms, which come into contact with aquatic environments. In the method, a pre-formed panel heater element is provided to the surfaces of the structure which are for submerging into water. The heater element is disposed at a predetermined depth from the surface of the structure, and energized at prescribed intervals and temperature which are effective to kill and prevent settlement of larvae on the surface of the structure. The pre-formed panel heater element consists of an inner layer composed of a fabric of electrically conductive fibers encapsulated in fiberglass/resin; two outer fiberglass/resin layers disposed on opposing surfaces of and encapsulating said inner layer; and electrical leads connected to said conductive fibers and adapted to receive power from a power source.
