The riser of claim 6 further comprising at least one annular recess with a strap disposed therein, wherein the recess is circumferentially disposed about the exterior surface of the assembly body at an axial position displaced from the positions of the first and second projections and displaced from the position of the plurality of wave-energizable apparatuses, the strap securing the identification assembly to the riser body. 8. The riser of claim 1 wherein the plurality of wave-energizable apparatuses are each retained within a recess in a shield, wherein each shield is disposed between the interior and exterior surfaces of the assembly body. 9. The riser of claim 1 further comprising at least one energizing recess in the exterior surface of assembly body adjacent to one of the plurality of wave-energizable apparatuses for directing energy for energizing the adjacent wave-energizable apparatus. 10. The riser of claim 9 wherein the exterior surface of the assembly body includes two annular projections encircling the assembly body and projecting radially therefrom, wherein the at least one energizing recess is disposed at an axial position between the two annular projections, andwherein the plurality of wave-energizable apparatuses are disposed at an axial position between the two annular projections. 11. The riser of claim 10 wherein the two annular projections comprise a flexible material. 12. The riser of claim 1 wherein the plurality of wave-energizable apparatuses includes information regarding the riser, wherein the information includes information regarding at least one of: riser design information; riser identity information; riser use information; riser installation information; riser test information; riser quality control information; riser observation information. 13. The riser of claim 1 wherein at least two of the plurality of wave-energizable apparatuses comprise radio frequency identification apparatuses. 14. The riser of claim 1 wherein the assembly body comprises a heat-resistant non-conducting fabric material with the plurality of wave-energizable apparatuses disposed therein. 15. The riser of claim 14 wherein the fabric material comprises at least two layers of material and the plurality of wave-energizable apparatuses are disposed therein and are free from contact with the riser body. 16. The riser of claim 14 wherein the fabric material comprises heat-shrink material. 17. The riser of claim 14 wherein at least two of the plurality of wave-energizable apparatuses comprise radio frequency identification apparatuses. 18. A subsea riser comprising a tubular subsea riser body having an interior surface, an exterior surface, and two spaced-apart ends,an identification assembly on the riser body,the identification assembly having an assembly body and a plurality of wave-energizable apparatuses in the assembly body,the assembly body having an interior surface, an exterior surface, and a channel formed by the interior surface, wherein a part of the riser body exterior surface is positioned within the channel,the assembly body extending around and releasably secured on the riser body,each wave-energizable apparatus being positioned within the assembly body and circumferentially spaced about the riser body,the assembly body having two ends, the two ends connected together,the exterior surface of the assembly body having at least one annular recess for a strap,a strap disposed within the at least one annular recess, the strap securing the identification assembly to the riser body, andthe assembly body having at least one annular projection projecting radially from the exterior surface of the assembly body and encircling the assembly body. 19. A subsea riser identification assembly comprising an assembly body securable around the body of a tubular subsea riser, the assembly body having an exterior surface,a plurality of wave-energizable apparatuses within the assembly body, the plurality of wave-energizable apparatuses including information about the riser,at least one annular projection encircling the assembly body and axially spaced from the axial position of the plurality of wave-energizable apparatuses,at least one annular recess, the recess circumferentially disposed about the exterior surface of the assembly body and axially spaced from the at least one annular projection and axially spaced from the plurality of wave-energizable apparatuses, anda strap disposed within the at least one annular recess, the strap configured to secure the identification assembly to the riser body,wherein the assembly body is circumferentially extendable around the riser body and comprises two ends connectable together. 20.
