moved downwardly with respect to rig floor 12 due to the weight of wellbore tubular string 24 directions such as upwardly downwardly outwardly and the like are intended to provide easy understanding of the invention with respect to the attached figures and should not be construed in any way as limiting the invention it will be understood that various relative positions of the components may be used during transportation assembly and the like compression platform 20 is preferably but not necessarily circular and preferably is guided by a corresponding cylindrical interior of shock table body 16 compression platform 20 defines bore 22 therein for receiving wellbore tubular string 24 therethrough body 16 preferably has a lower support surface 26 which also defines a bore 28 therethrough for receiving wellbore tubular string 24 compressible section 31 is contained within body 16 and lower support surface 26 compressible section 31 may comprise cylinders such as independent elastomer cylinders or other types of compressible cylinders to provide a spring like effect compressible section 31 engages compression platform 20 and is compressed as compression platform 20 moves downwardly within body 16 in a presently preferred embodiment compression section 31 be designed to provide a constant compression rate for decreasing dynamic forces however if desired a two stage compression rate for decreasing dynamic forces.
