Structural Damping Test for the BP Shah Deniz Risers

摘要

A pluck and decay, structural damping test was conducted onrna 1/3 scale steel riser section in air, in an attempt to quantifyrnthe damping coefficients of single pipe and multi-pipe riserrnsystems, and to understand the damping mechanisms involved.rnThe test rig consisted of a vertically cantilevered pipe, fixed atrnthe base and with provisions to add inner pipes to turn intornconcentric multi-pipe configurations. The results of this testrnprogram are probably the first large scale damping datarnapplicable to steel riser systems.
