1. An apparatus comprising: an inflexible body having a cylindrical shape and dimensioned to surround an underlying structure capable of experiencing a vortex induced vibration, the body having a first section and a second section, the first section having a first edge and a second edge parallel to a longitudinal axis of the body and the second section has a first edge and a second edge parallel to the longitudinal axis of the body, and the first edge of the first section is attached to the first edge of the second section by a hinge, and the second edge of the first section and the second edge of the second section are separable from one another such that the body is operable to be positioned around an underlying structure and the body is free to rotate around an underlying structure;at least four substantially straight and inflexible blade members, wherein at least two of the substantially straight and inflexible blade members extend from a portion of the first section adjacent an underlying tubular and at least two of the substantially straight and inflexible blade members extend from a portion of the second section adjacent an underlying structure, wherein a length dimension of each of the blade members is parallel to the longitudinal axis of the body and the blade members are substantially evenly circumferentially spaced around the body, and wherein each of the blade members are a single, integrally formed unit dimensioned to suppress the vortex induced vibration of the structure when the body is positioned around the structure; andan interlocking assembly for holding the second edge of the first section and the second edge of the second section in a closed configuration around an underlying tubular, wherein the interlocking assembly comprises a first interlocking member formed by one of the blade members extending from the first section and a second interlocking member formed by one of the blade members extending from the second section, wherein the first interlocking member and the second interlocking member are capable of interlocking with one another to secure the first section to the second section in the closed configuration. 2. The apparatus of claim 1 wherein at least one of the blade members comprises a slot dimensioned to receive a band member for securing the first section and the second section around the structure. 3. The apparatus of claim 1 wherein at least one of the blade members comprises a substantially triangular shape. 4. The apparatus of claim 1 wherein the first interlocking member comprises a first substantially hollow triangular structure extending from the second edge of the first section and the second interlocking member comprises a second substantially hollow triangular structure extending from the second edge of the second section, wherein the second substantially hollow triangular structure is dimensioned to fit within the first substantially hollow triangular structure. 5. The apparatus of claim 1 wherein the first section and the second section are dimensioned to cover less than an entire circumference of the structure. 6. The apparatus of claim 1 wherein a channel is formed along an interior surface of the body, the channel dimensioned to receive a collar positioned around the structure so as to restrain vertical movement of the body about the structure. 7. The apparatus of claim 6 wherein a recess is formed around the structure, wherein the recess is dimensioned to receive the collar so as to prevent vertical movement of the collar about the structure. 8. An apparatus comprising: a cylindrical body dimensioned to surround a tubular capable of experiencing a vortex induced vibration (VIV), the cylindrical body having a first section, a second section, a third section, and a fourth section capable of being separated and positioned around a tubular; andat least two blade members that are approximately 90 degrees apart extend from each of the first section, the second section, the third section and the fourth section, and wherein each of the first section, the second section, the third section and the fourth section have at least one of the blade members extending substantially perpendicular to an end of the section that is parallel to a longitudinal axis of the body and that interfaces with another section, and wherein the blade members are directly attached to one another when the cylindrical body is positioned around a tubular, and the blade members having a length dimension parallel to a longitudinal axis of the body and dimensioned to suppress a vortex induced vibration of a tubular when the cylindrical body is positioned around a tubular. 9. The apparatus of claim 8 wherein the blade member comprises a slot dimensioned to receive a band member for securing the first section and the second section around the structure. 10. The apparatus of claim 8 further comprising a first interlocking member attached to the first section and a second interlocking member attached to the second section, wherein the first interlocking member and the second interlocking member are capable of interlocking with one another to secure the first section to the second section around the structure. 11. The apparatus of claim 10 wherein the first interlocking member and the second interlocking member are enclosed within the blade member. 12. The apparatus of claim 8 wherein the first section and the second section, the third section and the fourth section are dimensioned to cover less than an entire circumference of the structure. 13. The apparatus of claim 8 wherein a channel is formed along an interior surface of the cylindrical body, the channel dimensioned to receive a collar positioned around the structure so as to restrain vertical movement of the cylindrical body about the structure. 14. A method of suppressing vortex induced vibration (VIV) about a structure comprising: positioning a plurality of VIV suppression devices around a structure, each of the VIV suppression devices comprising a cylindrical body member having at least four separable sections operable to encircle the structure and each of the sections having at least two substantially straight blade members having a length dimension parallel to a longitudinal axis of the body member, the blade members being substantially evenly spaced in a circumferential direction around the structure and directly connected to an outer surface of a portion of the cylindrical body member adjacent the structure and having a rectangular cross-sectional shape with the length dimension extending outward from the outer surface of the cylindrical body member, the cross-section being taken perpendicular to a length of the blade member and wherein the plurality of VIV suppression devices cover less than 70% of a section of the structure. 15. The method of suppressing VIV of claim 14 wherein positioning comprises: positioning the body member around the structure; andinserting a strap through the blade member and around the body member. 16. The method of suppression VIV of claim 14 wherein positioning comprises: positioning the body member around the structure; andinserting a collar positioned around the structure within a channel formed along an interior surface of the body member.
