Paper presented at the First ISOPE Ocean Mining Symposium, November 21–22, 1995
Paper Number: ISOPE-M-95-012
... ABSTRACT: In order to reduce the longitudinal vibration of the pipe string in mining manganese nodules from deepsea bottoms, the investigation of the shape effects of various buffers attached to the string reported that the resonance amplitude of the buffer whose shape caused a larger drag...
