ABSTRACT:
A fairing system is disclosed for protecting a cylindrical marine element from drag and vortex induced vibration. A noncorrosive fairing shroud is rotatably mounted about the cylindrical marine element and defines an annular region between the exterior of the cylindrical marine element and the inside of the fairing shroud and at least one copper element is mounted at the annular region to discourage marine growth at the fairing shroud-cylindrical marine element interface. This enables the fairing to remain free to weathervane to orient most effectively with the current Another aspect of the present invention is a method for protecting a substantially cylindrical marine element from vortex-induced vibration in which a rotatable fairing is installed about the marine element and a marine growth inhibitor is mounted in active communication with the annular interface of the rotatable fairing and the cylindrical marine element.
