Structural Damping Test For The Bp Shah Deniz Risers

Abstract

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractA pluck and decay, structural damping test was conducted on a 1/3 scale steel riser section in air, in an attempt to quantify the damping coefficients of single pipe and multi-pipe riser systems, and to understand the damping mechanisms involved. The test rig consisted of a vertically cantilevered pipe, fixed at the base and with provisions to add inner pipes to turn into concentric multi-pipe configurations. The results of this test program are probably the first large scale damping data applicable to steel riser systems.
