A vortex induced vibration suppressor and method is disclosed. The apparatus
includes
a body that is a flexible member of a polymeric (e.g., polyurethane) construction.
A plurality of helical vanes on the body extend longitudinally along and helically
about the body. Each vane has one or more openings extending transversely there
through. A longitudinal slot enables the body to be spread apart for placing the
body upon a riser, pipe or pipeline. Tensile members that encircle the body and
pass through the vane openings enable the body to be secured to the pipe, pipeline
or riser.
