1. A vortex-induced vibration (VIV) suppression apparatus comprising: at least one body having a wall dimensioned to at least partly envelope a tubular member in an interior area of the body;at least one fin protruding outward from an exterior surface of the wall; andat least one stand-off member positioned along an interior surface of the wall for spacing the body away from the tubular member, the stand-off member having a protruding portion formed by the interior surface of the wall and an indention portion formed by the exterior surface of the wall. 2. The VIV suppression apparatus of claim 1, wherein the stand-off member is formed by molding the protruding portion into the wall of the body. 3. The VIV suppression apparatus of claim 1, further comprising a filling element dimensioned to be positioned within the indention portion. 4. The VIV suppression apparatus of claim 3, wherein the filling element in the indention portion makes the exterior surface of the wall even at the indention portion. 5. The VIV suppression apparatus of claim 3, wherein the filling element is bonded to the indention portion. 6. The VIV suppression apparatus of claim 3, wherein the filling element is held in place by a band placed over the filling element. 7. The VIV suppression apparatus of claim 3, wherein the filling element comprises a compressible material capable of regaining an original shape. 8. The VIV suppression apparatus of claim 1, wherein the stand-off member runs along a circumferential direction of the body. 9. The VIV suppression apparatus of claim 1, wherein the stand-off member runs parallel to the fin. 10. The VIV suppression apparatus of claim 1, wherein the stand-off member runs along a longitudinal direction of the body. 11. The VIV suppression apparatus of claim 1, wherein the indention portion is dimensioned to accommodate a band in the indention portion for securing the VIV suppression apparatus to the tubular member. 12. The VIV suppression apparatus of claim 1, wherein the stand-off member stops at the fin. 13. The VIV suppression apparatus of claim 1, wherein the fin is formed during a molding process of the body. 14. The VIV suppression apparatus of claim 1, wherein the body comprises at least two modular pieces that fit together to form the body.
