... and reducing the axial motion and stress of a pipe. Using the 3-D nonlinear pipe code, 3DNLPIPE, the previous analysis (Cheng and Chung, 1996, 1997) showed design and operation principles following which arrangements of the axial vibration dampers at proper positions along the pipe, even without the joints...

Paper presented at the First ISOPE Ocean Mining Symposium, November 21–22, 1995
Paper Number: ISOPE-M-95-005
... ABSTRACT: Previously, a very long vertical pipe was modeled and used for the simulation of its dynamic behavior for lifting manganese nodules or crusts from 800 to 6,00G-m deep seafloor. Recently, a pipe with elastic (flexible) joints was introduced (Cheng and Chung, 1995; Chung, Cheng...
