A method and apparatus for stabilizing and burying a conduit in a waterbed is disclosed. A plurality of spoilers are placed on the conduit at longitudinally and radially different positions to promote self-burial, reduce vortex-induced vibration, prevent upheaval buckling, minimize future corrective work by continuous reburial of the under water conduit or pipeline.

The present invention is directed to a fairing system for the reduction of vortex-induced vibration and minimization of drag about a substantially cylindrical element immersed in a fluid medium. The fairing system includes a plurality of cylindrical shells rotatably mounted about a cylindrical element immersed in a fluid medium. Each cylindrical shell has opposing edges defining a longitudinal gap configured to allow the shells to snap around the cylindrical element. The longitudinal gap has a circumference of about 120&deg; relative to the circumference of each shell. Alternatively the longitudinal gap can have a circumference of about 60&deg; relative to the circumference of each shell. The shells also include a fin positioned along the each opposing edge of the longitudinal gap, in which each fin extends outwardly from each shell. The fins are positioned on each shell so as to reduce vortex-induced vibration and minimize drag on the cylindrical element.
