초록 ▼

A vortex induced vibration suppressor and method is disclosed. The apparatus includes a body that is a flexible member of a polymeric (eg. polyurethane) construction. A plurality of helical vanes on the body extend longitudinally along and helically about the body. A longitudinal slot enables the body to be spread apart for placing the body upon a riser, pipe or pipeline. Adhesive and/or bolted connections optionally enable the body to be secured to the pipe, pipeline or riser.

1. A vortex induced vibration suppression apparatus comprising; a) an elongated one piece body of flexible polymeric material, the body having a wall surrounding a continuous, open ended bore; b) the one piece body including a plurality of helical vanes on the body extending along the length thereof each vane tracking a helical path; c) a riser pipe that carries the body, the riser pipe occupying the bore; d) a slot that extends through the wall; and e) wherein the slot does not transversely cut across one or more of the helical paths. 2. The vortex induced vibration suppression apparatus of claim 1 wherein the slot extends along one of the vanes. 3. The vortex induced vibration suppression apparatus of claim 1 wherein there is a removable connection that holds the body together. 4. The vortex induced vibration suppression apparatus of claim 3 wherein the removable connection is comprised of a plurality of spaced apart bolted connections. 5. The vortex induced vibration suppression apparatus of claim 1 wherein the body is of a polyurethane material. 6. The vortex induced vibration suppression apparatus of claim 1 wherein the body is between 50 and 95 Shore A durometer. 7. The vortex induced vibration suppression apparatus of claim 1 wherein the body is between 50 and 75 Shore D durometer. 8. A vortex induced vibration suppression apparatus comprising; a) an elongated one piece body of flexible polymeric material, the body having a wall surrounding a continuous, open ended bore; b) a plurality of helical vanes on the body extending along the length thereof; and c) a riser pipe that carries the body, the riser pipe occupying the bore; d) a longitudinal slot that extends through the wall, enabling the body to be separated to afford access to the bore; and e) wherein the slot separates one of the vanes into first and second longitudinally extending vane sections. 9. The vortex induced vibration suppression apparatus of claim 8 wherein there is a removable connection that holds the vane sections together at the slot. 10. A vortex induced vibration suppression apparatus comprising; a) an elongated body of flexible polymeric material, the body having a wall surrounding a continuous, open ended bore; b) a plurality of helical vanes on the body extending along the length thereof; c) a longitudinal slot that extends through the wall, enabling the body to be separated to afford access to the bore; and d) a spacer that is removably attachable to the body, the spacer including a rounded outer surface that enables the spacer and body to roll and the spacer having a bore shaped to fit the elongated body and its helical vanes.
